This change adds support for the KHR_materials_dispersion glTF extension, which introduces a dispersion property for refractive materials.
The dispersion property controls the angular separation of colors transmitting through a refractive object, allowing for more realistic rendering of materials like glass and diamonds.
Changes include:
- Added a dispersion property to the material definition.
- Updated the shaders to incorporate the dispersion effect in the refraction calculations.
- Added a new test case for dispersion.
- Updated the material documentation to include the new dispersion property.
The new `linearFog` material property, when set to `true` enables a
simplified fog calculation. The fog equation becomes linear which is
unrealistic, but more efficient to compute. In some situations with
a shallow fog range, it doesn't make a huge difference visually.
In this mode, height falloff and in-scattering are ignored.
The linear equation slope is calculated from the regular parameters to
match the slope of the real equation at a camera height. If
`heightFalloff` is disabled, set to 0, the `density` parameter
exactly corresponds to the slope of the equation in [1/m] units.
- Move directories into more descriptive organization
- src_mdbook, src_markdeep, src_raw
- mdbook will be generated from mdbook
- markdeep will be generated to html
- raw will be copied without modification
- Add script that will run on a succesful commit to main. This
script will update /docs and commit the changes.
