CSE 287 Project - Raytracing Instructions: ● Your project must be an interactive program that responds to the keystrokes, as outlined in the keystroke document. ● Videos illustrate the behavior. of the project: ○ Video A ○ 0:00 Introduction 0:30 Lights 1:57 Shadows 2:15 Spotlight 3:25 Tie light to camera/world 5:05 Transparency 5:45 Shapes and textures ○ Video B ○ 0:00 Resizing 0:30 Reflections 1:28 Anti-aliasing ○ Video C ■ 0:00 Two viewports ● You may not talk with students from who have taken this course in previous semesters; you are expected to complete this project on your own. It is also worth noting that there are subtle differences between this semester’s code base and previous semesters. In addition, we may run scripts to detect unnatural similarities between all student submissions. ● You may not use glViewport or any other gl or glu functions. We never talked about these and you should not be using them. Of course, you may use glm functions. (70) REQUIRED FEATURES 1. (38) Lighting, shading, and shadows. The lighting/shading of your scene must include: a. (15) One positional light and the correct implementation of the equations to render the objects with a realistic appearance. Backfaces must be rendered. b. (2) Attenuation that can be turned on/off via keystrokes. c. (6) Spotlight. The spotlight will not illuminate any intersection points that fall outside the light’s cone. If outside the cone, the light considers the intersection point as black; otherwise, the intersection point is rendered like a regular positional light. (Note: spotlights often have a different approach for rendering the interior of the cone. Our class will simply render the interior of the cone in the normal fashion.) d. (15) Shadows. Implement shadows by checking shadow feelers for each surface intersection. If the shadow feeling intersects with another surface before the shadow feeler reaches the light source, that particular light should provide only ambient contribution. 2. (8) Objects. Your scene must include, at a minimum, the following objects, each with their own material common properties (e.g., gold): a. Cylinder with closed ends and aligned with Y axis. b. Cylinder with open ends and aligned with X axis. c. Cone d. Sphere e. Plane 3. (8) Textures. The Y-oriented cylinder must have its sides (the top and bottom must be solid but can appear as any material) textured with the any recognizable PPM file that you choose. Do this by merging the texel value and lighted value (using the underlying, lighted, material property) at a 50-50 proportions. 4. (8) Transparency. At least one object in your scene should be transparent. The position of the transparent object must be placed on a timer to illustrate that the display is correct, given its relative position to opaque objects. That is, the transparent object must move in front of and then behind opaque objects. 5. (8) Resizing. The display must not display skewed images when the window is resized. (30) CHOOSE ANY TWO ADDITIONAL FEATURES - 15 EACH 1. Light tied to world or camera. When the light’s position is (10, 10, 10), it is typically thought of as being at (10, 10, 10) in the global world coordinate system. However, it is sometimes useful to have the light’s position relative to the camera’s frame. Keystrokes should allow the user to switch between these two modes. Further, the keystrokes that alter the spotlight’s position and direction should respond accurately. 2. Reflections. Add inter-object reflections by tracing a reflection ray to the closest surface intersection for each view ray. Once generated, the reflection ray can be traced in exactly the same way as the viewing rays. The best way to accomplish this is by calling the traceIndividualRay method recursively and adding what it returns to the total color for the pixel. To do this, it is necessary to keep the recursion from being infinite. This can be accomplished by adding an additional parameter -- depth -- to the traceIndividualRay method. This parameter can be decremented prior to each recursive call. The recursion would stop when the value is less than or equal to zero. 3. Viewports. The scene will be rendered from two different vantage points. The two images will occupy the left and right halves of the screen respectively. The two camera positions must be chosen in a way to allow the user to obviously see that the two images come from the same scene, yet different enough to allow the user to discern that the images come from two different vantage points. 4. Anti-aliasing. Because of the discrete nature of raster image representation, rendered images will include aliasing artifacts. These artifacts create a jagged or stair stepped in objects that should appear smooth. In ray tracing applications, anti-aliasing can be performed by tracing multiple rays per pixel. Your approach should subdivide each pixel into the, say, 3x3 grid, casting one ray per subpixel. The resulting color should then be the average color of the 9 rays (for a 3x3). A 3x3 will provide a more refined image than a 2x2 or 1x1 grids. You must provide a report (PDF file) that contains: ● An itemized list of the functionalities that work and those that do not. ● Screenshots of your program’s display should be inserted into your report. The image should annotated to highlight the functionalities that were completed. This might include, for example, images of the scene with and without antialiasing. ● If you do not provide a report, missing items, or is inaccurate, 15 points will be automatically deducted from your overall score. Your report should not be misleading or deceitful.本团队核心人员组成主要包括硅谷工程师、BAT一线工程师，精通德英语！我们主要业务范围是代做编程大作业、课程设计等等。我们的方向领域：window编程 数值算法 AI人工智能 金融统计 计量分析 大数据 网络编程 WEB编程 通讯编程 游戏编程多媒体linux 外挂编程 程序API图像处理 嵌入式/单片机 数据库编程 控制台 进程与线程 网络安全 汇编语言 硬件编程 软件设计 工程标准规等。其中代写编程、代写程序、代写留学生程序作业语言或工具包括但不限于以下范围:C/C++/C#代写Java代写IT代写Python代写辅导编程作业Matlab代写Haskell代写Processing代写Linux环境搭建Rust代写Data Structure Assginment 数据结构代写MIPS代写Machine Learning 作业 代写Oracle/SQL/PostgreSQL/Pig 数据库代写/代做/辅导Web开发、网站开发、网站作业ASP.NET网站开发Finance Insurace Statistics统计、回归、迭代Prolog代写Computer Computational method代做因为专业，所以值得信赖。如有需要，请加QQ：99515681 或邮箱：99515681@qq.com 微信：codehelp
