What is the difference between your lite and full models

lizhan17 commented 1 day ago

test still colmap just follow original 3dgs implementation and early version of our codes. model is stored in ply and .pt file

lite and full model difers at mlp rendering. lite mode (no mlp) still can have good results and speed is also fast (even for 8k) . full model is for acchiving high quality results. Although we found with mlp fused in cuda, its speed is also very fast. (not fast at extreme high resolution). Remember mlp is per pixel rendering. while gs splatting is per tile splatting.
