For one - scene graph (including nested graphs), there is one unique QSGMaterialShader - instance which encapsulates the QOpenGLShaderProgram the scene graph uses - to render that material, such as a shader to flat coloring of geometry. - Each QSGGeometryNode can have a unique QSGMaterial containing the - how the shader should be configured when drawing that node, such as - the actual color to used to render the geometry. - - An instance of QSGMaterialShader is never created explicitely by the user, - it will be created on demand by the scene graph through - QSGMaterial::createShader(). The scene graph will make sure that there - is only one instance of each shader implementation through a scene graph. - - The source code returned from vertexShader() is used to control what the - material does with the vertiex data that comes in from the geometry. - The source code returned from the fragmentShader() is used to control - what how the material should fill each individual pixel in the geometry. - The vertex and fragment source code is queried once during initialization, - changing what is returned from these functions later will not have - any effect. - - The activate() function is called by the scene graph when a shader is - is starting to be used. The deactivate function is called by the scene - graph when the shader is no longer going to be used. While active, - the scene graph may make one or more calls to updateState() which - will update the state of the shader for each individual geometry to - render. - - The attributeNames() returns the name of the attributes used in the - vertexShader().
