In mid 2016, a number of contributors discussed another workaround to use Canvas textures in conjunction with effects/shaders: simply, by allowing an arbitrary Canvas to be registered as a '''material''' via SGMaterialLib, e.g. using an API in the form of <code>myCanvas.registerMaterial(name: "myCanvasMaterial");</code> | |||
Equally, materials would make it possible to easily use arbitrary effects and shaders per Canvas element: | |||
<syntaxhighlight lang="cpp"> | |||
Effect *effect = 0; | |||
SGMaterialCache* matcache = matlib->generateMatCache(b.get_center()); | |||
SGMaterial* mat = matcache->find( "myCanvasMaterial" ); | |||
delete matcache; | |||
if ( mat != NULL ) { | |||
// set OSG State | |||
effect = mat->get_effect(); | |||
} else { | |||
SG_LOG( SG_TERRAIN, SG_ALERT, "Ack! unknown use material name = myCanvasMaterial"); | |||
} | |||
</syntaxhighlight> | |||
