Project: QGIS
Version: 3.16
Further improvements for material handling were introduced, and a Gooch shading model was added. This improves the QgsAbstractMaterialSettings API, by:
- Adding icon support for registered material types (for use in the material selector combo box).
- Adds support for handling different rendering techniques to QgsAbstractMaterialSettings. Now material classes can indicate which rendering techniques they support (e.g. Triangles, Lines, InstancedPoints, etc.), and the material is only offered when it's compatible with the required technique.
- The technique handling in the gooch material widget was improved to avoid showing settings that have no effect in a particular context (e.g. hiding all but the ambient color choice for simple 2D line symbols).
- A new material, "Gooch", was added. This material gives a CAD style 3D render, where the shading is not dependent on appropriate lighting setup in a scene and where the 3D details are always visible, regardless of the lighting choice.
