Web8 de mar. de 2016 · A perspective projection defines a 3D area that projects out from the location of the camera along four boundary rays. The rays form a viewing frustum as shown in the image to the right. The frustum includes a front and back clipping plane that is parallel to the X-Y plane. Any models inside this viewing frustum will be rendered. WebThe perspective projection doesn’t actually create the 3D effect; for that, we need to do something called the perspective divide.
