hello people,
i need some help with maths.
i need to rotate ( or move) a mesh in a shader according to camera plane as shown below.
i know how to rotate them along objext xyz axis but still confused about transforming the object axis to camera plane axis.
what is the matrix i must apply to the vertex V so it will rotate (or move) only along camera plane x and y ?
any help much appreciated.
thanks millions.
