The QEffect class combines a set of techniques and parameters used by those techniques to produce a rendering effect for a material.
An QEffect instance should be shared among several QMaterial instances when possible.
Note: QEffect node can not be disabled.
QEffect *effect = new QEffect(); // Create technique, render pass and shader QTechnique *gl3Technique = new QTechnique(); QRenderPass *gl3Pass = new QRenderPass(); QShaderProgram *glShader = new QShaderProgram(); // Set the shader on the render pass gl3Pass->setShaderProgram(glShader); // Add the pass to the technique gl3Technique->addRenderPass(gl3Pass); // Set the targeted GL version for the technique gl3Technique->graphicsApiFilter()->setApi(QGraphicsApiFilter::OpenGL); gl3Technique->graphicsApiFilter()->setMajorVersion(3); gl3Technique->graphicsApiFilter()->setMinorVersion(1); gl3Technique->graphicsApiFilter()->setProfile(QGraphicsApiFilter::CoreProfile); // Add the technique to the effect effect->addTechnique(gl3Technique);
A QParameter defined on a QEffect overrides parameter (of the same name) defined in QTechnique and QRenderPass, but are overridden by parameter in QRenderPassFilter, QTechniqueFilter and QMaterial.
See also QMaterial, QTechnique, and QParameter.
Adds parameter to the effect. It sends an update to the backend. The parameter will be used to set a corresponding uniform value in the shader used by this effect.
Adds a new technique t to the effect. It sends an update to the backend.
Returns the list of parameters used by the effect.
Removes a parameter parameter from the effect.
Removes a technique t from the effect.
Returns the list of techniques used by the effect.
