[HELP/Guide] - Some Trivial Questions #14

Hello @yzslab @KaziiBotashev, need little help with following question:

How I can create a ply file for 3D planar image with 3D gaussians and assign view dependent color to them, so that I can view 3D planar image in SIBR viewer and observe view dependent effect when I rotate it?

  1. how to get final color of particular gaussian given there are gaussians at the back of that gaussian?

  2. Consider I want to replace 0 and 1 in binary image with "two particular gaussians on planar surface/object and associated view dependent colors" from two different ply files to generate 3D planar image. Difficulty is there are many gaussians at the back of this particular gaussian, how I can select these particular gaussians and their final color (alpha blending) from ply file and place them in the place of 0 and 1 in binary image to produce view dependent effect in created 3D planar image? Is it possible? Any other solution?

  3. How I can achieve same for rgb image?
