WnCC - Seasons of Code

Seasons of Code is a programme launched by WnCC along the lines of the Google Summer of Code. It provides one with an opprtunity to learn and participate in a variety of interesting projects under the mentorship of the very best in our institute.

Monte Carlo Path Tracing Renderer

Monte Carlo Path Tracing Renderer

--- This internship involves the implementation of a Monte Carlo Path Tracer. ### Monte Carlo Path Tracing Renderer In this project, you will implement a Monte Carlo Path Tracer. A path tracer is a kind of renderer in computer graphics. A renderer is responsible for generating the image or the graphics that you see on your screen. Even this text that you are reading is displayed via a font renderer. Path tracers are often used for photorealistic rendering, which means generating an image indistinguishable from a photograph. At the end of the project, you can expect to have a code capable of producing such images. As a primer, you should read Andrew Glassner's [Introduction to Ray Tracing]( ### Pre-requisites - At least two years of experience with CPP, awareness of gcc and make - A basic course on DSA ### Tentative Project Timeline I expect about 100 hours of work spread over ten weeks. |Week Number | Tasks to be Completed| |--- | --- | |**Week 1** |Read the book| |**Week 2** |Write an XML parser. This is the submodule that reads the scene.| |**Week 3** |Write the skeleton of the graphics pipeline. This involves implementing coordinate transformations| |**Week 4** |Implement the Ray and Object class. Most of the Path Tracing routine can be summarised as measuring intersection of instances of Ray class with instances of the Object class.| |**Week 5** |Implement Direct Lighting and Whitted Ray Tracing| |**Week 6** |Implement Recursive Rays to capture higher order light paths| |**Week 7** |Debugging buffer & Implement Jittering and Supersampling| |**Week 8** |Monte Carlo enters. Learn Sampling. Implement Diffuse Sampling and Area lights. Effects like soft shadows and colour bleeding start to appear| |**Week 9** |Debugging Buffer| |**Week 10**|Documentation, Generating Scenes, Videos ### Secondary Learning Goals Apart from learning about path tracers and rendering, you can expect to learn about the following: - Monte Carlo Sampling - Basics of ImageMagick - OpenMP Parallelization. ### Repositories The project will be done in groups of two. We will consider minor variations in the raytracers, Swati ([swati-rt]( and Revati ([revati-rt](
