How to get the world coordinates in post progress？

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…

This is kinda the same idea, you might be able to covert parts of it.

Otherwise you can make all the meshes switch over to a shader that displays their world position, and then pass that as a texture buffer to the postpass.

there are a few other ways to do it to.
