This question majorly resides in the camera simulation study. In the Ray Tracing method, the rays are generated from the camera origin to each pixel in the image matrix. Extending these rays, intersection with the triangles (3D Mesh) is computed and corresponding RGB values are stored in the respective pixels.
My question is if in a particular IFOV of a camera more than one triangle resides in that GIFOV, how the RGB values are computed? Say 3 triangles share the same pixel for a particular GIFOV then, how these 3 RGB values are integrated, and what is the final RGB value to be stored for that pixel?.
Basic principle is to use a weighted combination of all the relevant values to generate the single pixel. Actual algorithm can differ from one application to another.
