Hi everyone. I doing some test in blender. I need to identify the object not visible from the camera view though it exists in the scene. I have tried bvh1.overlap(bvh2) and https://stackoverflow.com/questions/57463072/how-do-i-know-if-an-object-is-inside-the-view-frustum-of-a-camera-in-blender-bp To check whether the object is overlapping or inside the frustum. Even I tried the mesh.ray_cast from small cube to camera location using the given link: https://blenderartists.org/t/how-to-use-ray-cast/702131/3
when I am doing ray_cast from small_cube to camera I get True. Please help me out and make me understand what I am missing or doing wrong.
