Hi Yura
Hi,
I have a transform matrix and I want to apply it in shader. I pass it into
uniform and set gl_Position =
gl_ModelViewProjectionMatrix*my_transfrom_matrix*gl_Vertex.
If I set translate only, everything is ok. If I set translate and scale -
translate multiplies by scale and transform is wrong (object is too far if
scale>1.0). If I apply this transform not using shader (by SetMatrix)
everything is ok. What I am doing wrong?
Matrix multiplication is not cummutative in every case.
Try
gl_Position = gl_ModelViewMatrix * matrix * gl_ProjectionMatrix *
gl_Vertex.
Cheers
Sebastian
Thank you!
