- So now that we've seen some renders and some side-by-sides…of the Path Tracer versus the VCM Integrator,…let's take a look at a few diagrams,…just to kind of really illustrate…what's happening behind the scenes.…Like how is the renderer doing this?…Why is the VCM doing certain things…better than the Path Tracer, etc., etc.?…So let's do some just simple diagrams…to see how the light is passing…through our three dimensional scene.…Now, on the left here, we have an eye,…that's your eye, the viewer.…
And there's a 3D scene depicted behind the grid…of all the dots as the light is bouncing through the scene.…And where it says, "Pixels," that's basically…our two-dimensional representation of our objects.…So in our case, it's a monitor.…If you're doing a painting,…it would be a piece of paper or a canvas.…So that's pixels on a screen,…and it's throwing camera rays, so where the eye is,…if you could replace that with the camera,…it's throwing camera rays into the scene.…And every time it hits that dot there,…it's bouncing off of an object.…
