Assignment代写：2D Mesh

下面为大家整理一篇优秀的assignment代写范文- 2D Mesh，供大家参考学习，这篇论文讨论了二维网格。二维游戏中的经典布局方式莫过于二维网格布局。在二维网格布局的基础上，还可以实现基于网格的碰撞检测，算法实现简单，且效果较好。

In this assignment, we will work with a 2D mesh or graph of vertices, edges, and triangles. At the vertices we store colors loaded from an image in .ppm format. The goal of this assignment is to reduce the total size of the mesh, but still provide a reasonable approximation of the original image. The images below show meshes with approximately 80,000 triangles, 10,000 triangles, and 1,000 triangles (from left to right), displayed with and without the edges between the triangles drawn with white lines.

To perform this simplication, we will use a standard mesh processing operation, the edge collapse, which is illustrated below. First, we identify an edge in the mesh that should be removed (drawn in blue). Next, we locate the two triangles on either side of that edge (drawn in light blue) and remove these triangles from the mesh. Finally, we locate all triangles using exactly one of the two endpoints of the edge and change that endpoint coordinate to the midpoint of the collapsed edge. Note: We reuse one of the endpoints of the collapsed edge, while the other is deleted. After the edge collapse is nished, the mesh has 1 fewer vertex, 2 fewer triangles, and 3 fewer edges (the blue edge and 2 green edges are removed). Note that if the edge to be collapsed is on the boundary of the image/mesh, the collapse will result in a mesh with 1 fewer vertex, 1 fewer triangle, and 2 fewer edges.

In performing an edge collapse, a local area of the mesh is modied. Triangles change area and edge change length. In the diagrams above we see that the green edges (the edges that were touching one of the endpoints of the collapsed edge) change length. The orange edges (which share a vertex with one or more of the green edges) do not change length; however, their status as legal or illegal may change. After performing an edge collapse, you should recalculate both the length and the legal/illegal status of the green & orange edges.

英文论文目录写作讲解

英文论文中的目录，就是相当于导读图。一般来说，论文中的目录会放在篇首，以便读者一眼就能看到，下面就给大家讲解一下英文论文目录的写作。

为读者选读论文中的某个分论点时提供方便。长篇论文，除中心论点外，还有许多分论点。当读者需要进一步了解某个分论点时，就可以依靠目录而节省时间。

目录一般放置在论文正文的前面，因而是论文的导读图。要使目录真正起到导读图的作用，必须注意：准确。

目录必须与全文的纲目相一致。也就是说，本文的标题、分标题与目录存在着一一对应的关系。

http://www.51due.net/online-tutoring/writing-skills/sample32581.html

清楚无误。目录应逐一标注该行目录在正文中的页码。标注页码必须清楚无误。完整。目录既然是论文的导读图，因而必然要求具有完整性。也就是要求文章的各项内容，都应在目录中反映出来，不得遗漏。

目录有两种基本类型：用文字表示的目录。用数码表示的目录。这种目录较少见。但长篇大论，便于读者阅读，也有采用这种方式的。

内容提要是全文内容的缩影。在这里，勾画出全文的整体面目；提出主要论点、揭示论文的研究成果、简要叙述全文的框架结构。

内容提要是正文的附属部分，一般放置在论文的篇首。写作内容提要的目的在于：

为了使指导老师在未审阅论文全文时，先对文章的主要内容有个大体上的了解，知道研究所取得的主要成果，研究的主要逻辑顺序。

因此，内容提要应把论文的主要观点提示出来，便于读者一看就能了解论文内容的要点。

以上就是关于英文论文目录的写作讲解，希望能够帮到大家。

Paper代写：The similarities and differences between Mark Twain and Huckleberry Finn

下面为大家整理一篇优秀的paper代写范文- The similarities and differences between Mark Twain and Huckleberry Finn，供大家参考学习，这篇论文讨论了马克·吐温和哈克贝利·费恩的异同。马克·吐温是美国非常著名的作家，他是在密西西比河的河边长大的。他的小说《哈克贝利·费恩历险记》也是世界文学的一大成功之作，人们也发现，马克·吐温和小说主人公之间有着惊人的相似之处。除了马克·吐温早期经历外，两者的故事背景都是发生在密西西比河。

Mark Twain, whose name has always finds its way onto the list of the America’s top 50 writers on the history, was born and raised up by the river side of the Mississippi. Also set by the Mississippi River, his novel Adventures of Huckleberry Fin was a great success of the world literature. There was a remarkable resemblance between the author himself and the main character of the novel Huckleberry, which made people fall into confusion—“was huckleberry actually Mark himself?” or “was Mark trying to write a biography in somebody else’s name?”. However, when people were making efforts trying to get answers of those problems, they would encounter one elements inevitably, which is the base of the background of the story and also where the author had spent his early years, the Mississippi River. To trace back to the origin of the work, people may ask, what if Mark Twin was not born and raised up by he river of Mississippi? Would he still work out such a masterpiece? And my answer to this question is no. From my point of view, it was his life with Mississippi that provided the inspiration and the base to form up such a novel. What’s more, the situation of people’s life around the Mississippi River enabled Mark to look into people inner desire at that time, giving him the strength to fight for the equality for people with black skin. For him, Mississippi didn’t only stand for a river, but also for a life that people should do something for it. Thus, without Mississippi, I think Mark Twin wouldn’t have such a work.

Firstly, Mississippi was the background for both the author and the novel. Mark Twain was born in the vill of Hannibal, Missouri. He was not enjoying his childhood as his father died when he was 12 years old, which made him reluctantly dropped out of the school and went to his brother, who was working as an editor and the young Mark served as an apprentice in order to make a living. By the time of the early 1850s, Mark happened to enjoy the prosperity of the shipping industry on the Mississippi River, at which time he spared every effort to learn how to drive and began a new life as a helmsman. During this period, he drove to many place on the treacherous Mississippi, where he acquired the ability to fight against the dangerous current and see through the every surface of the nature. He then changed his original name of Samuel Langhorne Clemens into the famous one of Mark Twain, which is a term or slang among the helmsman meaning “the leadsman's cry for a measured river depth of two fathoms (12 feet), which was safe water for a steamboat.”(Clemens, Samuel L, 1917) He was so familiar with this river that he regarded the Mississippi River as his hometown without hesitation.

http://www.51due.net/writing/research-paper/sample32579.html

Besides Mark’s early experience, his novel too shared the same place as the background of the story. In the book, affectionate and exhaustive words were used to describe the scenes of the river, and the whole book even was filled with native slangs that made people recognize it as somehow rude. What’s more, the main character Huckleberry was also a helmsman who knew well about the Mississippi. The author used much of his own shipping knowledge to plot the story, making the novel a convincing story that fit the time and truth, which was one of the success the novel had made.(Cornish, F. H, & M. Twain, 1982) Considering the basic elements of book was contribute by Mark’s early experience over the river, and the unescapable truth that such details and skills of the native staffs were more than hard to make up on one’s imagination, it is quite difficult for people to deny the contribution of author’s personal experience to the novel, that is to say, if Mark Twain was not born by the Mississippi River, he couldn’t make up such a literately precise and vivd story of Huckleberry.

Secondly, the life over the Mississippi River made Mark twain who he was and stimulates the born of the book. To see from the history, the escape from the society into the wild due to the abomination of the frightfulness and hypocrisy of the society has been one of the most common themes of the novel in the 19th century. Similarities were found in those books as most of them regarded the human and nature as an organic whole where human was one essential part, but the form of the society, especially the industrial revolution, undoubtedly set human and the nature apart, turning the species losing its initial quality of kindness, purity and peace. The commercialization of the modern society was recognized as the reason why people were turning selfish, cruel and reckless with greed. Thus, the people who were thought had not completely lost their hearts were dying to get back to the nature, to embrace the though and origin of the wild. They struggled to give up and get rid of what they had as a man who lived in society. From this point of view, to return to the wild meant to return to oneself. And Mark had also tried to conduct this theme in the book of Adventures of Huckleberry Fin.

The story of the novel began with the escape of the main character, a white teenager whose name was Huckleberry Fin, and the whole story was about how he managed to ship along the great Mississippi and finally went to his destiny. Though the young and obstinate Huckleberry was adopted by a widow who was tremendously attempting to cultivate him, his situation couldn’t be changed considering his surroundings—his alcoholic father who used violence upon him as well as abused him frequently, his step mother who was trying to confine him by the name of traditional education. He had foreseen his future if he keeping being nude and do nothing to fight against it, which made he had no choice but to go on the way to escape. On depicting how Huck desperate for freedom, Mark shed a little light on how he hated the being of society. He recorded the backwardness of the villas on the Mississippi in the 1840s to 1850s, documented the dilapidated scenes of the farmland, the severe contradiction between the rich and the poor, the cruel racial oppression, which were all true at the time. it is clear to see that Mark was trying to hold the time before the industrial revolution, when the country life was still happy and peaceful. Himself was hoping to run away, but somehow he couldn’t do such a thing. So that he wrote it into a novel. That is to say, if he hasn’t experience all of those which he was not willing to experience, he might not have wanted to escape the society, making the novel never a possibility.

Last but not the least, Mark Twain’s early experience by the river side encouraged him to fight for the human rights of black people. By the time when the Adventures of Huckleberry Fin was published , The Emancipation Proclamation has already been put into effort for decades, which is to say, Mark Twain was actually raised up under the effectiveness of The Emancipation Proclamation. But the truth turned out to be, the status of black people wasn’t improved in the southern areas. The situation got even worse as there emerged organizations for example the infamous 3K group that tortured black people and murders happened frequently. After seeing all the slaughters that happened near him it is not difficult to imagine Mark Twain’s anger and pessimistic toward the temporary society.

Later Mark Twain changed his anger into words and spread them in the story Huckleberry. He spared much space for the escape of a black slave whose name was Jim. Jim was facing the most dark institution at the time being, the slavery, he was unable to fight but only to escape. Along with the help of Huck, this two teenagers began their epic journey among the watershed of Mississippi. Through the eyes the two kind teenagers the author reviewed the social civilization of the regions. Sadly, the result turned out to be negative. He regarded the civilization of commercialization to be corrupt and depressive. (Jackson, R, 2002) Also, in Adventures of Huckleberry Fin, civilization seemed to be the everything that stopped people from loving, sharing and being kind. There were no freedom and dependence to mention in such society, even the dignity of one’s was treated as merchandise. The dark pace of society stimulated Mark Twain to fight, not solely with book to publish, but also to walk onto the stage of history to voice for the black people. Thus people may say it was by the River of Mississippi where Mark Twain was enlightened with the awareness to fight against the racialism. Without it, he wouldn’t have made such a success in the literature world, nor would he promote human right for black people.

It is clear that Huckleberry showed up initially in The Adventures of Tom Sawyer, where the author was holding a quite ambiguous attitude towards the modern civilization and the society. (Bennett, J, 1974) Actually Huckleberry was not to have his own adventure written into novel, but as Mark Twain gradually went into the maturity of his thoughts of fighting against the society and racialism, his story was then created. it is not difficult to see his effort on promoting the idea of returning to the nature and to eliminate racialism to the whole world.

There are theories that adversity makes a talented person, and Mark Twain might be a typical model to prove that. His early experience of living in a corrupt atmosphere motivated him to pounder over the social issue and inspired him to write down his dream. He realized the responsibility he should shoulder instead of solely running away from it. However, he still wished he had not lived in this society, thus he made up his consolation, huckleberry, a kind, brave young white man who was desperate for freedom as well as willing to give a hand to black people. The story of Huckleberry is also what he had dreamed for his youth. It was based on his youth but was given a better future.

As a conclusion, if Mark Twain was not born and raised up by the Mississippi River, the whole story of Adventures of Huckleberry Fin would be totally different or even not be created, what’s more, the situation of black people would be quite different form now without his great effort in the history. Mississippi was not only the background for both the author and the book, but also the place that enabled the author to have the thought of writing such a book. He created fun stories and plots that revealed the truth appearance of both the backward American society and the corrupt social customs. What’s more, it is the symbol for the author to fight against inequality at that time. He used the book as a weapon. Though Huckleberry was different from Mark Twain himself, he attached all his hope onto Huckleberry. He is his consolation, a escape form the reality and his daydream.

Paper代写：The experience of studying in the United States

下面为大家整理一篇优秀的paper代写范文- The experience of studying in the United States，供大家参考学习，这篇论文讨论了美国留学的经历。作者在去美国留学后，改变了很多。在学校，作者在意的不只是自己的成绩，更开始关心他人，社会问题，这些都让作者感觉到自己是这个大家庭的一份子，并能感觉到生活的爱与美好。而在学习方面，作者也学会了自我学习，不再依靠furor的辅导，而是学会自己探索问题，寻找各种办法解决不明白的事情。总的来说，留学美国之后，作者成长了许多。

I went to the high school in the United States. The life and study here, exerts a profound influence on my perception of religion, changes my learning method and attitude, and at last nurture my self-reliance.

The religious atmosphere of Catholic girls school exerts a lot of influence on me when I was pursuing higher education in the United States. I came to the United States in 2015 and went to Maria Regina High School. It is because that I expect to understand the different religious culture. Although I am a Muslim, I was still well integrated in this religious school. For the first time, I have enrolled at Catholic girls school, and experienced some change gradually. After three years of study here, I find that although the world's two largest religions have their own very unique features, there are some commonness between those two religions. The life at school taught me to care more about others, and social issues, such as war and peace, arms, human trafficking, abortion, the death penalty, to understand poverty, to help the poor etc. And this schooling allows me to be more caring. This is what many practitioners of Muslims in China advocate. It gets me to realize some common cores of both religions. And more importantly, a more tolerant and inclusive attitude is gradually formed.

http://www.51due.net/writing/research-paper/sample32578.html

In terms of learning, I began to form the habit of self-learning, and no longer relied on tutor's counseling only. And in school, I did not care my own achievements or final result merely. On the contrary, I learned to explore problems by my own , and find a variety of ways to solve things. This helps me to get a better way to learn. And the testing in the form of GPA makes me have a more serious attitude towards learning. I had to rely on tutoring in the home country in the past. There was no sense of self-learning, under the domestic fixed examination system. I feel that all the pursuit is just for the exam results. Now, I begin to seriously treat the assignments, and stress the accumulation of knowledge in a slow and peaceful way, rather than focusing only on the pursuit of the final score. Knowledge I acquire now can really be absorbed. In addition, my knowledge help to shape my correct views on the world. Now, I am good at solving problems, and curious about the unknown world. This is really an important improvement of learning for me.

I have made another great improvement after I came to the United States: I grew up a lot and learned the self-reliance. When a person carrying a large baggage from Beijing to sit 13 hours of aircraft to New York, he or she must know what the word “self-reliance” means. When I came to the U. S. at first, ordering food at McDonald's was a huge challenge for me. And when foreigners greet me, such as saying “how is it going”, I did not knowhow to react because in the country where I came from, I have been learning “how are you”. Now I am familiar with the American environment. I feel good when I am traveling alone in the United States, and like to go to different states to experience different cultures. I feel that I am part of this new big family, and can feel the love of life and goodness of people around me. I feel more personally how developed the United States is, and how advanced education industry is. This free country is a dream country for me.

Years at Catholic girls school make me full of enthusiasm, sincere, and sympathetic emotions for life. Learning experience here also makes me like to challenge adversity. I am determined to make a bigger contribution to the society by applying to study in higher institution.

Essay代写：Student writing

下面为大家整理一篇优秀的essay代写范文- Student writing，供大家参考学习，这篇论文讨论了学生的写作情况。大多数中国学生在大一的时候都有学术论文作业，但他们对如何组织学术论文却没有深刻的理解，他们的论文总是混乱的。其中原因可能是学生缺乏写作经验，而且他们并没有把提纲写好。为此，老师在平常的教学中，就比较注重写作的基础教学。

The term of teacher denotes acommunication bridge that is able to teach or spread knowledge to students, especially in schools. It is accustomed to calla professor or teacher as a “bridge” in the academic services. A commonly accepted idea is that the teachers need to define the teaching purposes, and methods in accordance with their teaching philosophy. Teaching philosophy plays an important role in the teaching activities for higher efficiency. However, once without the clearly goals and the methods, the teaching philosophy will be condemned. The issue of unclear elements of teaching philosophy has to be clarified due to their ubiquity.

The Goals for the ENG 107 Class

Most of Chinese students in ENG 107 First-Year Composition, do not have a deep understanding of how to organize the academic paper. On the other hand, their papers are always chaotic due to the organization, even though they have enough elements for their papers that teachers want. The reason I think is the students are short of writing experience, and they did not work the writing outline that come from the professor very well.

http://www.51due.net/writing/essay/sample32575.html

Thus, the most important mission for me to support these students is to teach them how to organize their paper. Moreover, I am trying my best to teach them how to make a clear guideline by themselves.

My approach to teaching has been inflinfluenced by my overcome of obstacle of writing problems found in most Chinese students enrolled in ENG 107 First-Year Composition. When some students see the essay topics, most of them have a blank mind, and have nothing to say and write. There is little planning of the whole essay. It is a step that is often ignored(Magher). And in the regular writing training, even if the essay is written, it is rarely for them to carefully modify and explain the main argument of essay. Students in the usual writing ignored the importance of a clear guideline and organization of the writing. Thus, a rigid translation of their mother tongue makes the words blunt, and semantic incoherent. In their article, they lack the ability to express and argue personal views and ideas in a reasonable way, and are writing articles only in a narrative manner, with the lack of personal views and emotional expression. This phenomenon is widespread, posing a challenge to the improvement of students’ writing ability . Therefore, in the daily teaching process, I must pay attention to basics of teaching of writing. Before writing the essay, it is primary to writing out the outline with clear argument and thesis. It is “a main idea or thesis which is a short summary of the central idea” (“Learn about the benefits of essay outlining for students and teachers”). It is to help train students to use the language of the orderly thinking, and help students improve their ability to master the language. At the same time, the order of writing outlines at first, and then writing essays is in line with the principle of the teaching of writing; from the simple to complex content. This step by step training principles in English writing can effectively promote the internalization of language knowledge and improve the correct use of English language.

Conclusion

Teaching philosophy is closely related to the teaching purposes, and methods. During the teaching, there was an obstacle of writing problems found in most Chinese students enrolled in ENG 107 First-Year Composition. Under my teaching philosophy of being acommunication bridge, I set my teaching goals as a deep understanding of the academic paper and teaching methods as a training of how to make a clear guideline by themselves before the writing. With this teaching practices, I learned that a guideline can help students express and argue personal views and ideas in a reasonable way and the importance of teaching step by step .
