Public Functions
Detailed Description
Warning: This utility class is only functional when running with the default backend of the Qt Quick scenegraph.
The vertex color material will give each vertex in a geometry a color. Pixels between vertices will be linearly interpolated. The colors can contain transparency.
The geometry to be rendered with vertex color must have the following layout. Attribute position 0 must contain vertices. Attribute position 1 must contain colors, a tuple of 4 values with RGBA layout. Both floats in the range of 0 to 1 and unsigned bytes in the range 0 to 255 are valid for the color values.
Note: The rendering pipeline expects pixels with premultiplied alpha.
QSGGeometry::defaultAttributes_ColoredPoint2D() can be used to construct an attribute set that is compatible with this material.
The vertex color material respects both current opacity and current matrix when updating it's rendering state.
