What is the camera transform?

The camera transformation is the transformation matrix that can be used to position and orient an object or a model in the scene that represents the camera.

Which matrix is used to convert world coordinates to camera coordinates?

The world coordinate system is a left-handed coordinate system, this is important because the PROJECTION matrix in OpenGL assumes a right-handed coordinate system. The matrix [R T] is a 3x4 transform which maps world coordinates to camera coordinates.

How do you convert camera space to world space?

The space in which points are defined with respect to the camera coordinate system. To convert points from world to camera space, we need to multiply points in world space by the inverse of the camera-to-world matrix.

What is a projection transformation?

projection transformation. [data conversion] The mathematical conversion of a map from one projected coordinate system to another, generally used to integrate maps from two or more projected coordinate systems into a GIS.
