QgsMaterialSettingsRenderingTechnique
Material rendering techniques 3.
@ Points
Point based rendering, requires point data.
@ Triangles
Triangle based rendering (default)
@ TrianglesFromModel
Triangle based rendering, using a model object source.
@ Lines
Line based rendering, requires line data.
@ TrianglesDataDefined
Triangle based rendering with possibility of datadefined color.
@ InstancedPoints
Instanced based rendering, requiring triangles and point data.
@ TrianglesWithFixedTexture
Triangle based rendering, using a fixed, non-user-configurable texture (e.g. for terrain rendering)
