G-Buffer layout

...........................................................................
|

: : Red : Green : Blue : Alpha :
|
|
:........................:...........:.........:............:.............:
|
|
: G-Buffer 0 (RGB10_A2) : Normal : Roughness : Material ID :
|
|
: G-Buffer 1 (RGBA8) : Base Color : Metallic :
|
|
: G-Buffer 2 (RGBA8) : Material specific params : Occlusion :
|
|
: G-Buffer 3 (R11G11B10) : Emission : - :

:........................:............:.........:...........:.............:

|
|
Notes:
|
|
- Two 10-bit channels is enough for normals, as long as we are using
|
|
octahedron normal encoding.
|
|
- Since the Material ID is stored in 2 bits, we can only have 4 different
|
|
material types. The maximum value (3 or 1.0) is reserved for the standard
|
|
PBR metallic-roughness material.
|
|
- In 'Material specific params' fancier materials can use up to 24 bits
|
|
to encode any information they might need (e.g. a clearcoat layer needs
|
|
to store the clearcoat amount and roughness).
|
|
- Materials that are very different from the standard should write
|
|
whatever they need in the G-Buffer without adhering to this layout and use
|
|
the stencil buffer and a separate render pass.

Auto exposure using a luminance histogram
|
|
Based on the article by Alex Tardif:
|
|
https://www.alextardif.com/HistogramLuminance.html
|
|
|
|
Instead of using a compute shader, we run two fragment shaders. The first
|
|
calculates a partial histogram of the rows of the input HDR texture, and
|
|
the second aggregates them together to obtain a single histogram.
|
|
|
|
The last step, which calculates the average scene luminance from the
|
|
histogram, is identical even though it is implemented as a fragment shader.
|
|
|
|
This technique will find the average luminance after multiplication by the
|
|
albedo. This is not correct, but the alternative (keeping a luminance
|
|
texture) is too expensive and not worth the trouble.
