Hi All,
Inside the channel draw call back function, I am
making some calls to read the current projection and
viewing matrices. I get different results from
glGetFloatv() and the pfGet$_Mat() functions; the
values of the returned matrices are different. Does
anyone know why? I thought these two functions are
equilvalent!?
Code fragment:
...
pfDraw();
// GL
GLfloat projMatD[16];
GLfloat modelViewMatD[16];
glGetFloatv(GL_PROJECTION_MATRIX, projMatD);
glGetFloatv(GL_MODELVIEW_MATRIX, modelViewMatD);
// PF
pfMatrix ViewMat;
pfMatrix ProjMat;
pfGetViewMat(ViewMat);
pfGetProjMat(ProjMat);
...
=====
Thanks,
faculaganymede
