Comments
The camera object is used along with the viewport to project the vector image into a 2D plane.
LVectorBase::SetCamera and LVectorBase::GetCamera are the functions used for manipulating the camera object.
The camera can be used with either 2D or 3D vector images.
pVECTORCAMERA is a pointer to a VECTORCAMERA object.
