About rigid transformation matrix?

[K-M-Ibrahim-Khalilullah]

Thanks for your good repo. Would provide the notation of your 4x4 rigid transformation matrix? It will easier to understand, what they are? or any other link?

It seems like rigid_transformation() does the following:

• Convert a 3D view frustum in the camera coordinate from Cartesian coordinates into Homogenous coordinates
• Perform transformation
• Convert the homogenous coordinates back into Cartesian coordinates

Henceforth, get_view_frustum() extract the view frustum for each frame by utilizing its depth and intrinsic and pose.
