WebDescription. tform = rotm2tform (rotm) converts the rotation matrix rotm into a homogeneous transformation matrix tform. The input rotation matrix must be in the … Homogeneous coordinates are ubiquitous in computer graphics because they allow common vector operations such as translation, rotation, scaling and perspective projection to be represented as a matrix by which the vector is multiplied. By the chain rule, any sequence of such operations can be multiplied out into a single matrix, allowing simple and efficient processing. By contrast, using Cartesian coordinates, translations and perspective projection cannot be expressed as ma… cadshare ltd
