[osg-users] Matrix multiplication order

[Florian GOLESTIN]

Hi everyone !

I don't get why in GLSL you transform a vertex like this:


Code:
vec4 result = matrix * vertex;



While in OSG I have to do it in the reverse order :


Code:
osg::Vec4 result = vertex * matrix;



Is it due to the Matrices major mode that are different from OpenGL and OpenSceneGraph ?

Thanks for demystifying me!
