Shader effects
For importing shaders into 3D scenes, Qt Quick 3D has its own framework. Shader effects enable the full, raw power of a graphics processing unit to be directly utilized via vertex and fragment shaders. Too many shader effects can result in increased power consumption and sometimes slow performance, but when used sparingly and carefully, a shader can allow complex and visually appealing effects to be applied to a visual object.
Both shaders are bound to the vertexShader and fragmentShader properties. Every shader's code requires a main(){…} function, which is executed by the GPU. A variable with the prefix qt_ is provided by Qt. To understand the variables in shader code, have a look at the OpenGL API reference document.
When working with ShaderEffect or subclassing QSGMaterialShader in QML applications using Qt Quick, the application must provide a baked shader pack in the form of a .qsb file. The Qt Shader Tools module includes a command-line tool...
