PLY file render problems #63

Hello, I have a PLY file with you steps but I'm not sure how to render it with RGB color. The file contains properties like f_dc_1, f_dc_2, and so on. I'm not sure how to use these properties to render the point cloud with color

Thank you for your question! The properties such as f_dc_1, f_dc_2, etc., are spherical harmonics attributes of the 3DGS point cloud. These attributes enable view-dependent rendering when the same point is observed from multiple viewpoints. They are not directly RGB colors but are used to model and render the point cloud under varying viewing conditions.
