Hello,
I try to multiply a vector by a matrix. The look like the following lines:
osg::Matrix matrix = osg::Matrix(...);
osg::Vec4 vector = osg::Vec4(...);
osg::Vec4 result = matrix * vector;
Now, it doesn't work. But when I try to invert the matrix and the vector
it works. Is the order transpose in terms of multiplications? For
example I would calculate the projection pipeline like the following line:
result = projectionMatrix * viewMatrix * vertex
But in OSG I must write:
result = vertex * viewMatrix * projectionMatrix
But why?
Cheers,
Martin
