Detailed Description

The Effect type combines a set of techniques and parameters used by those techniques to produce a rendering effect for a material.

An Effect instance should be shared among several Material instances when possible.

A Parameter defined on a Effect overrides parameter (of the same name) defined in Technique and RenderPass, but are overridden by parameter in RenderPassFilter, TechniqueFilter and Material.

Effect {
    id: effect

    technique: [
        Technique {
            id: gl3Technique
            graphicsApiFilter {
                api: GraphicsApiFilter.OpenGL
                profile: GraphicsApiFilter.CoreProfile
                majorVersion: 3
                minorVersion: 1
            }
            renderPasses: [
                RenderPass {
                    id: gl3Pass
                    shaderProgram: ShaderProgram {
                        ...
                    }
                }
            ]
        }
    ]
