Hi, I see the 3D Gaussians in your project page, several ellipsoids. So how to visualize the density and scale?

XPandora commented 2 months ago

You may use the SIBR viewer provided by the Gaussian Splatting repo to view static Gaussians.

To visualize Gaussian dynamics, we modify the original rendering code (diff-gaussian-rasterization) to do that. The basic idea is to only render the foremost kernels.

@XPandora Hi, can you please provide the modified diff-gaussian-rasterization code, or describe exactly what was modified?

XPandora commented 2 weeks ago

Hi, sorry, I recently reinstalled my computer's system and no longer have the modified code available. However, from what I recall, the primary modification was related to function. The main change was to adjust the alpha calculation so that the foremost Gaussian kernels would occlude those behind them.
