TODO

• Account for the fact that a larger minor axis "hardens" splat edges
  • Maybe shift the alpha gradient, or incorporate into shader
• Rework SplatBinder system to collect all splat objects in the scene and combine their buffers
• Write shader to calculate Gaussians at runtime
  • Texture lookups are slow on mobile
• Write shader that prevents pixel overdraw
  • Applies cumulative alpha,while drawing back to front, and writes to the Z-buffer after a certain threshold
• Optimize CalculateAxes.hlsl
• Allow splat data buffers to be accessible by other VFX Graphs
• Support SOGS format
• Add exception reporting and handling for incomplete splat data
• Add support for other PLY data types and endianness
• Add support for ASCII PLY data
• Fix the header parsing logic in SplatImporter.cs
• Add more thorough checks in SplatDataBinder.cs

DONE

• Rewrite SH Array to use interleaved RGB rather than contiguous data per channel
• Switch to using ByteAddressBuffers instead of loops in CalculateSH.hlsl
  • Used StructuredBuffer<float3> instead

NOTES

• Does VFX Graph calculate the Update and Render blocks before applying Z-test?
