Title: Get modelViewMatrix from object
Post by: kkl on November 16, 2014, 12:50:53 pm

Hi Egon,

Is there anyway to get modelViewMatrix from object? I need it for multiple sub-meshes location and direction (crowd animation with hardware skinning), so I can animate the submesh by using only one object to reduce drawcall.

Translate the matrix returned by getWorldTransformation() by the negated camera position and multiply the resulting matrix with the camera's rotation matrix.
