v0.1.6

What's new

The python interface for tile_bounds has been abstracted away, and instead project and rasterize take in a block_width parameter controlling the tile size as well as the CUDA block size. CUDA was refactored to allow dynamic block sizes, which enables ND rasterization speedups by taking better advantage of shared memory.

v0.1.5

What's new?

• Improved pytorch implementation of project_gaussians inside _torch_impl.py
• Screen space blur compensation for rasterizing tiny gaussians from Mip-Splatting
• Bugfixes

v0.1.4

What's Changed

Fix a major bug in rasterization since version 0.1.0. (Issue and PR)

v0.1.3

What's changed

• Alpha rendering and supervision with return_alpha flag in rasterize.py
• Fix bug with 0 gaussians in view

v0.1.2.1

What's Changed

• Fixing latent issue with single intersection
• API update: Function.apply() will be deprecated soon. It's recommend to directly call the python functions. The full list of updates:
  • ProjectGaussians.apply -> project_gaussians
  • RasterizeGaussians.apply / NDRasterizeGaussians.apply -> rasterize_gaussians
  • BinAndSortGaussians.apply -> bin_and_sort_gaussians
  • ComputeCumulativeIntersects.apply -> compute_cumulative_intersects
  • ComputeCov2dBounds.apply -> compute_cov2d_bounds
  • GetTileBinEdges.apply -> get_tile_bin_edges
  • MapGaussiansToIntersects.apply -> map_gaussian_to_intersects
  • SphericalHarmonics.apply -> spherical_harmonics

v0.1.1

A few small fixes:

• Build might stuck if Ninja got interrupted with a lock file uncleaned.
• Assert in ND Rasterization.

v0.1.0

Highlights

Support ND features for Gaussians.
