A render mode dictionary specifies how the surfaces of a 3D model are rendered. Different render modes reveal different aspects of the model, from photorealistic shading to wireframe outlines.

The AC entry names the auxiliary colour applied to edges, vertices, or backfaces depending on the render mode. The FC entry names the face colour mode, controlling how face colours are determined.

The O entry specifies the opacity of the model surfaces. The CV entry holds the colour value used for certain render modes such as solid or transparent solid that require a uniform colour.
