Hi, I''m using this function to check wheter my ray intersect with my mesh.. Do you think it works, cause I can never make it work ?? I mean, if I have my ray based on the world coordinate and then the mesh is still on its local coordinates right ?? Do I need to transform my ray first ?? or what ? How do I make it worked ??

How do you get m_matLocal, cause usually I use matIdentity for the local for the mesh.

hi yanuart,

m_matLocal just refers to the object''s current world transformation/matrix, just replaced m_matLocal with the matrix you used to to transform your object at world space,
