Cogl.Pipeline.prototype.set_shininess

function set_shininess(shininess: Number(gfloat)): void {
    // Gjs wrapper for cogl_pipeline_set_shininess()
}
  

Sets the shininess of the pipeline, in the standard OpenGL lighting model, which determines the size of the specular highlights. A higher shininess will produce smaller highlights which makes the object appear more shiny.

The default value is 0.0
