If the ShaderEffectSource is defined to be an image, + it is directly uploaded as a texture. The texture(s) containing the source pixelcontent are then bound to graphics + pipeline texture units. Finally a textured mesh is passed to the vertex- and fragmentshaders which + then produce the final output for the ShaderEffectItem. It is possible to alter the mesh structure by defining + the amount vertices it contains, but currently it is not possible to import complex 3D-models to be used as the mesh. + + It is possible to define one or more ShaderEffectItems to be a ShaderEffectSource for other ShaderEffectItems, but ShaderEffectItem + should never be declared as a child element of its source item(s) because it would cause circular loop in the painting. + + A standard set of vertex attributes are provided for the shaders: + + \list + \o qt_Vertex - The primary position of the vertex. + \o qt_MultiTexCoord0 - The texture co-ordinate at each vertex for texture unit 0. + \endlist + + Additionally following uniforms are available for shaders: + + \list + \o qt_Opacity - Effective opacity of the item. + \o qt_ModelViewProjectionMatrix - current 4x4 transformation matrix of the item. + \endlist + + Furthermore, it is possible to utilize automatic QML propertybinding into vertex- and fragment shader + uniforms.
