Detailed Description

Associates a Renderable object to an Effect and Transform.

An Actor can associate one Renderable for each LOD (level of detail) using the lods() function. The rendering order of an Actor is defined by its rendering rank, and block, see setRenderRank() and setRenderBlock() for the details.

Note:

The same Renderable can be bound to more than one Actor at the same time
The same Effect can be bound to more than one Actor at the same time
The same Transform can be bound to more than one Actor at the same time

Remarks:

An Actor must always have a Renderable and Effect bound. If no Transform is specified the Renderable will be rendered as if it had an identity matrix transformation.

Uniforms

The Uniforms defined in the Actor and the ones defined in the Shader must not overlap, that is, an Actor must not define Uniforms that are also present in the Shader's Uniform and vice versa.
