Detailed Description¶
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 severalQMaterial
instances when possible.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 an Effect is overridden by aQParameter

QEffect
([parent=None])¶ - Parameters
parent –
QNode
-
PySide2.Qt3DRender.Qt3DRender.QEffect.
addParameter
(parameter)¶ - Parameters
parameter –
QParameter
Adds
parameter
to the effect. It sends a QPropertyNodeAddedChange to the backend. Theparameter

addTechnique
(t)¶ - Parameters
t –
QTechnique
Adds a new technique
t
to the effect. It sends a QPropertyNodeAddedChange to the backend.
