Hello opensourcedev members.
I'm trying to create a version of snowstorm that will render in stereo. The
device I'm working on requires that the screen be split two side by side
viewports and each viewport must render a parallel camera translated by x units.
I have the two viewports working but I cannot seem to sort out how to translate
the camera. I figure the best place to do it is in pipeline.cpp. below is part
of my code (I set up the viewports back in llviewerdisplay.cpp before calling
renderGeom)
I'm not the best opengl programmer. Can anyone assist me or point me in the
right direction?
Thanks!
Kip
void LLPipeline::renderGeom(LLCamera& camera, BOOL forceVBOUpdate, int
LEFTRIGHT)
{
glh::matrix4f saved_proj = glh_get_current_projection();
glh::matrix4f saved_view = glh_get_current_modelview();
if (LEFTRIGHT==0) {//set up left projection matrix
gGL.matrixMode(LLRender::MM_PROJECTION);
gGL.loadIdentity();
saved_proj.set_translate(glh::vec3f(2.f, 2.f, 0.f));//or some fixed
value
glh_set_current_projection(saved_proj);
}
if (LEFTRIGHT==1){
//do nothing to the right eye for now
}
...
}
