v1.0.0

A Major Update to V1.0.0

• Comparing to the official implementation, gsplat enables up to 4x less training memory footprint, and up to 2x less training time on Mip-NeRF 360 captures, and potential more on larger scenes.

• Support extremely large scene rendering, which is magnitudes faster than the official CUDA backend diff-gaussian-rasterization.

• Extra features, including batch rasterization, N-D feature rendering (faster), depth rendering, sparse gradient etc.

Full Changelog: v0.1.6...v0.1.7

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)
