About Renderer Objects

A renderer object (or, more briefly, a renderer ) is a type of QuickDraw 3D object that you can use to render a model--that is, to create an image from a view and a model. A renderer controls various aspects of the model and the resulting image, including:

the kinds of geometric objects the renderer can draw without decomposing them into simpler objects
the parts of objects to be drawn (for example, only the edges or filled faces)
the types of lights that are available and the illumination model to be applied
the types of shaders that are available and kinds of interpolation that can be performed

To render an image of a model, you first need to create an instance of a renderer object. To do that, you'll need to know which types of renderers are available. QuickDraw 3D provides routines that you can use to get information about the available renderers and their capabilities. Once you've decided which renderer you want to use, you then create an instance of that renderer and attach it to a view. You can do this in several, ways, by calling Q3Renderer_NewFromType and then Q3View_SetRenderer , or by calling the function Q3View_SetRendererByType .
