Project 4: David Grosman

[davidgrosman]

• Project Link
• dgrosman
• Completed Features (and bells and whistle for cow):
  • Vertex shading. (_vertexTransformAndAssembly in rasterize.cu)
  • Primitive assembly with support for triangles read from buffers of index and vertex data. (_primitiveAssembly in rasterize.cu)
  • Rasterization. (_rasterize in rasterize.cu)
  • Fragment shading. Using Blinn-Phong with ambient, diffuse and specular light effects. (render in rasterize.cu)
  • A depth buffer to store and depth test fragments.
  • Fragment-to-depth-buffer writing (with atomics for race avoidance).
  • Toon Shading by Post processing the fragment buffer divided into "tiles" and using Sobel Filter.
  • Backface culling, optimized using thrust's stream compaction.
  • UV texture mapping with bilinear texture filtering and perspective correct texture coordinates.
  • Support for rasterizing additional primitives:
    • Lines or line strips (Press W to toggle between model drawing and wireframe mode).
    • Points (Press P to toggle between model drawing and point-cloud mode).
• Note: You must include "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\lib\x64\cudadevrt.lib;" in your Project Properties' Linker Input's Additional Dependencies field to get the Project running. This is because I am using thrust::remove_if() for my back-face culling phase. (And I couldn't figure out in which CMakeList file to specify it in)
