How mvp matrices value are applied in Qt3D Example https://doc.qt.io/qt-5/qt3d-simplecustommaterial-example.html

How mvp (Model view projection) matrices are set in the code as mentioned in the above link code.

Vertex shader:
void main()
{
// Transform position, normal, and tangent to world coords
worldPosition = vec3(modelMatrix * vec4(vertexPosition, 1.0));

// Calculate vertex position in clip coordinates
gl_Position = mvp * vec4(worldPosition, 1.0);

}
