outward_normal

Open jiro-26 opened this issue 1 year ago • 4 comments

In the function outward_normal in render.py, when method == 'finite_differences' the gradient is calculated by tetrahedron algorithm. This is suitable for SDF, but how about Occupancy Function? Is there any theoritical background that it is suitable for Occupancy Function too under some conditions? (for example, if the tetrahedron is small enough and the Occupancy Function is implemented on MLP?) Or, this outward_normal is not recommended to use for Occupancy Function?
