void mir::compositor::GLRenderer::tessellate ( std::vector< graphics::GLPrimitive > &  primitives, graphics::Renderable const &  renderable  ) const

virtual

tessellate defines the list of triangles that will be used to render the surface.

By default it just returns 4 vertices for a rectangle. However you can override its behaviour to tessellate more finely and deform freely for effects like wobbly windows.

Parameters

[in,out]	primitives	The list of rendering primitives to be grown and/or modified.
[in]	renderable	The renderable surface being tessellated.

Note

The cohesion of this function to GLRenderer is quite loose and it does not strictly need to reside here. However it seems a good choice under GLRenderer while this remains the only OpenGL-specific class in the display server, and tessellation is very much OpenGL-specific.
