Younger brother my plan is three student at hkust, contact Unity is almost one year, and the recent research about Ray tracing and Ray marching, achieved the effect of a few simple, in Unity is to achieve after treatment, and in the vertex shader almost nothing,

My question:

CG language will be eliminated? CG language into the rasterizer manner, does not apply to light track way?

Ray tracing and Ray marching in Unity can only be done with post-processing?

In the framework of ray tracing, texture mapping and illumination calculation process is what?

For example I want to do Ray marching cloud volume, can only use post-processing? Find a few cloud volume not particles is improved version of the IQ bosses, the horizon as if also reference IQ bosses, that, I have a idea, set up a camera, give some bottom cloud model object layer, through the depth map, FBM GouChengYun form, such as is possible, please? I want to replace Ray marching,,, although is still a post-processing way


I was an amateur rookie, there are a lot of questions, know little, a lot of things might be misunderstanding, hope bosses understanding, looking forward to bosses to solve!
