Features completed:

  • Point cloud renderer
  • Gaussian splat renderer

Feedback:

  • There were some weird snags I got caught on. Some were my own fault, but some were real funky.
    • Firefox seems to run the point cloud renderer alright, but doesn't like the sorting algorithm or some other part of the splat renderer pipeline. I didn't figure out exactly where it was, but I was stuck thinking I implemented something wrong for some time.
    • I tried developing the project on my laptop running MacOS, but it just seemed to crash my whole desktop environment. The point cloud renderer seems to work like Firefox, but somewhere along the splat renderer pipeline it just seems to freeze up.
    • Quaternions are evil, got stuck for a bit on the order of components stored in them
    • Something really simple: there are no safeguards on writing buffers of the wrong type from the host to the device. I was stuck on weird splat sizing for a while until I realized the array I made on the host side for render settings was for Uint32 instead of Float32.
  • Maybe the codebases for this and homework 4 could be made more similar. Not necessary per se but would be nice
