Project 6: Mauricio Mutai

• Repo Link
• Features:
  • Compute shader (shaders/compute.comp)
    • Updates blades by applying forces (wind, gravity, recovery)
    • Multiple wind forces available, selected via #define
    • Orientation culling
    • View-frustum culling
    • Distance culling
    • Wind direction can be used to determine blade's final color
  • Grass pipeline stages
    • Vertex shader (shaders/grass.vert)
    • Tessellation control shader (shaders/grass.tesc)
      • Dynamically tessellates blades to varying levels of detail depending on distance from camera
    • Tessellation evaluation shader (shaders/grass.tese)
    • Fragment shader (shaders/grass.frag)
      • Two coloring modes, depending on which one was chosen in compute shader
        • Wind as color (no shading)
        • Lambert shading, with blades having constant green albedo color
  • Added NUM_BLADES as push constant for compute shader
  • Figured out how to read VkBuffer by copying it back into CPU memory
• Feedback: I struggled a lot to understand the Vulkan pipeline at first. I think more comments in the code explaining how things connect to each other would've helped.
