Render to smaller texture then take that to screen quad

Depth Sorted Ray Marching PostProccess

Thanks to a little help from @Evgeni_Popov with my math and depth calculations, we were able to create a depth sorted post effect that will allow raymarched scenes to be rendered with your normal scene. https://playground.babylonjs.com/#6Z7SIZ#16 Lots of work to go into it still, but here eventually I plan on passing all of BJS standard material stuff to the ray marched surfaces and you will be able to hopefully not tell the difference for general purposes. -TODO: Volumetric Absorption Ref…

Just look up Pryme8 and Ray marching on the forum and playground search, I’ve got quite a few playgrounds and different marching setups.

There are procedural texture examples, render target examples, post process examples. I’ve done multiples of each you will just have to do some code diving. You might have to rollback what version of BJS you are on too for some of them to work.
