[GLSL] getting the camera's position.
Author
How can i get the camera's position in World Space if i have the view matrix in GLSL?
I think it should be the last column of the inverted view matrix.
The view matrix transforms from world space to camera space. What you're looking to do is to transform 0,0,0 in camera space into world space, so that explains the inversion.
