Set uniform and animate uniform variables
I am using Qt3D with plain C++. I can't figure out how to access uniform variables of custom materials with custom shaders.
``` waveAnimation = new QPropertyAnimation(m_custom_material); waveAnimation->setTargetObject(m_custom_material); waveAnimation->setPropertyName("height"); waveAnimation->setDuration(80); waveAnimation->setStartValue(QVariant::fromValue(0.f)); waveAnimation->setEndValue(QVariant::fromValue(40.f)); waveAnimation->setLoopCount(-1); waveAnimation->start();
I found a class names QShaderData but the documentation was useless for me and I didn't achieve anything with try and error. It would be awesome if some could give me a hint ...
Alright solved it
Hi and welcome to devnet,
How did you solve it ?
You can access the uniforms with the parameter classes. So for example:
auto boneId = new Qt3DRender::QParameter(); boneId->setName("uBoneId"); boneId->setValue(QVariant(1)); customMaterial->addParameter(boneId);
