%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% ProjectMesh2Image: adaptor for type check and other pre-processing 
%
% FaceM: the nx3 matrix to hold the vertex indices
% VertexM: the mx3 matrix to hold the 3D vertex coordinates
% CamParamSA: the cell array of camera parameters
%				each cell contains a camera structure with these fields:
%		tcV: 3x1 vector, the translation vector
%		RcM: 3x3 matrix, the rotation matrix
%		fcV: 2x1 vector, the focal length in x and y direction
%		ccV: 2x1 vector, the camera center
%		imSizeV: 2x1 vector, the image size of the current camera
% channelModFactor: the factor to create distinctive face color, usually 2 or 4
% ScreenSizeV: the maximum size of the screen needed, (note the the rendered image size
%				can be smaller, but no bigger)
% zoomFactor: non zero to zoom the rendered image, must be integer
% ZNearFarV: the closest and furthest distance to generate the view frustum
