Instantiates:: QShaderProgram
Detailed Description▲
ShaderProgram class encapsulates a shader program. A shader program consists of several different shaders, such as vertex and fragment shaders.
Qt3D will automatically populate a set of default uniforms if they are encountered during the shader instrospection phase.
