Project 3: Vismay Churiwala

[vismaychuriwala]

Link to my Repo

Core Features Completed

• Shading kernel with BSDF evaluation (diffuse, perfect specular surfaces)
• Stream compacted path termination
• Sorting by material type
• Stochastic sampled antialiasing

Extended Features Completed

• Visual Improvements
  • Added support for refractive materials, and configurable strength of refraction, relection, diffusion of a material, tinted refraction added.
  • Depth-of-Field lens effect with configurable depth-of-field and lens radius.
• Mesh Improvements
  • Support for loading OBJ meshes along with corresponding .mtl files.
  • Bounding box culling per mesh (AABB).
  • Triangle Intersection test using the Möller–Trumbore algorithm.
• Performance Improvements
  • Added code to compute intersection parameters t in parallel per Geom object in a separate kernel (highly concurrent but very high memory usage, I will add block reductions for t_min in the future).

README Completion Checklist

• Cover image in readme does not use Cornell Box
• Descriptions, screenshots, debug images, side-by-side comparisons of features implemented
• Analysis
• Scenes and meshes included or linked
• Third-party library changes or compilation changes documented
• Bloopers (optional)

analysis and descriptions to follow soon.

Late Days Used

Too many - I had been sick for 2 weeks and I asked for an extension on Ed, professor told me to submit it when I could. I finished the core code requirements within 3 late days - but I didn't want to have a minimum project. I have tried added features and make a good readme after the deadline. Sorry for the delay - I've been working on the next assignment in parallel.

Project feedback

I liked the project, but I think the extra features have too little weightage when it comes to points. Features that took me multiple days are weighed 2 points. And these features are ones that make a massive difference in the capabilities of the project like mesh loading. I would've appreciated weightage proportional to time taken.
