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.
注意： 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 .

添加 参数 to the effect. It sends an update to the backend. The 参数 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 参数 from the effect.
Removes a technique t from the effect.
Returns the list of techniques used by the effect.
