Mics. types

type PGorillaFogSettings = pointer to TGorillaFogSettings;
type PRenderContext = pointer to TRenderContext;

TRenderPassMethod

enum TRenderPassMethod = ( RenderListToFBO, RectToFBO ) ;

The render pass method defines what is going to be rendered and where to.

Remarks

RenderListToFBO - will render all objects in renderlist with the provided render pass material. The output will be written to the FBO of your renderpass.

RectToFBO - will render on basis of the latest context FBO or on a attached renderpass output. The output will be written to the FBO of your renderpass.

TRenderPassRenderingProc

enum TRenderPassRenderingProc = ( DefaultRendering, ListRendering ) ;

Especially render passes may need different rendering techniques. So you can choose between: default and list rendering Default rendering uses multiple steps for rendering opaque and translucent elements and combining those afterwards. While list rendering is a simple rendering of all elements in renderlist. No post-processing renderpass will be needed, but this may lead to problems with transparency.
