default

Member Function Documentation

◆ ambient()

QColor QgsPhongTexturedMaterialSettings::ambient ( ) const

inline

Definition at line 59 of file qgsphongtexturedmaterialsettings.h.

◆ averageColor()

QColor QgsPhongTexturedMaterialSettings::averageColor ( ) const

overridevirtual

Returns an approximate color representing the blended material color.

Decompose an average color into Phong material components, and sets the material's colors accordingly.

Sets ambient and specular colors from the input color. This also sets the shininess parameter based on the metallic value.

Parameters
