View Full Version : Disney Explains Its Powerful New Hyperion Rendering Engine

Last year, FXGuide published a fantastically comprehensive look at Disney’s new rendering engine, but Disney itself has now released a great filmstrip-style video that explains its renderer (and rendering in general) in layperson’s terms:

that's pretty basic and not specific to it's renderer at all....thats the basics of all PT renders....and to the first point.....all rendering originates from the camera, even raytraced

The difference between the 2 is RT will fire secondary rays to each lightsource after the camera ray intersects an object, thereby can only calculate direct lighting...having to use non physically based methods to calculate indirect (ambient occlusion, final gather ect)

where by the brute force nature of a PT render calculating the entire path.... all lighting is taken into effect.

But Disneys render has a lot more going on separating it from a normal pathtracer

I believe photon mapping and bidirectional path tracing fires from the light source as well as the camera in hopes that the intersection of the two converges on a solution faster. But that is neither here or there.

This will be very good later for Disney VR if it ever happens
But look how many engineers worked on the implement, they
got all the gelt to throw at it.
