/**
|
||||
* The aim of this mesh material is to use information from a post processing pass in the diffuse color pass.
|
||||
* This material is based on the MeshPhysicalMaterial.
|
||||
*
|
||||
* In the current state, only the information of a screen space AO pass can be used in the material.
|
||||
* Actually, the output of any screen space AO (SSAO, GTAO) can be used,
|
||||
* as it is only necessary to provide the AO in one color channel of a texture,
|
||||
* however the AO pass must be rendered prior to the color pass,
|
||||
* which makes the post-processing pass somewhat of a pre-processing pass.
|
||||
* Fot this purpose a new map (`aoPassMap`) is added to the material.
|
||||
* The value of the map is used the same way as the `aoMap` value.
|
||||
*
|
||||
* Motivation to use the outputs AO pass directly in the material:
|
||||
* The incident light of a fragment is composed of ambient light, direct light and indirect light
|
||||
* Ambient Occlusion only occludes ambient light and environment light, but not direct light.
|
||||
* Direct light is only occluded by geometry that casts shadows.
|
||||
* And of course the emitted light should not be darkened by ambient occlusion either.
|
||||
* This cannot be achieved if the AO post processing pass is simply blended with the diffuse render pass.
|
||||
*
|
||||
* Further extension work might be to use the output of an SSR pass or an HBIL pass from a previous frame.
|
||||
* This would then create the possibility of SSR and IR depending on material properties such as `roughness`, `metalness` and `reflectivity`.
