Hello,
I would like to make a prerender camera that loop over the rendering of
its son's geometries until an event happens and then display the result
as a texture with the main camera..
mainloop(){
while(condition){
tex=prerender_camera.draw() //render to texture using fbo
}
maincamera.draw() //render the main scene using texture tex
}
(The condition depends on the post draw opengl state : an occlusion
query.. )
I have try a few tricks without success
Can you help me for this?.
