Detailed Description

Constructor & Destructor Documentation

GUI_PrimitiveHook::GUI_PrimitiveHook ( const char *  hook_name,
GUI_RenderMask  mask = GUI_RENDER_MASK_ALL 

Only one primitive hook will ever be created. Each hook requires a name for identification and error reporting. A hook can target all renderers, a subset, or a specific renderer.

Member Function Documentation

virtual GR_Primitive* GUI_PrimitiveHook::createPrimitive ( const GT_PrimitiveHandle gt_prim,
const GEO_Primitive geo_prim,
const GR_RenderInfo info,
const char *  cache_name,
GR_PrimAcceptResult processed 

Create a new primitive based on the GT or GEO prim. The info and cache_name should be passed to the GR_Primitive constructor. 'processed' should indicate that the primitive is consumed (GR_PROCESSED), or processed but available for further hooks or internal Houdini processing (GR_PROCESSED_NON_EXCLUSIVE). GR_NOT_PROCESSED should only be returned if a GR_Primitive was not created. Hooks with GUI_HOOK_FLAG_PRIM_FILTER do not call this method.

Reimplemented in HDK_Sample::GR_PrimTetraHook.

virtual GT_PrimitiveHandle GUI_PrimitiveHook::filterPrimitive ( const GT_PrimitiveHandle gt_prm,
const GEO_Primitive geo_prm,
const GR_RenderInfo info,
GR_PrimAcceptResult processed 

For hooks with GUI_HOOK_FLAG_PRIM_FILTER, this method is called instead of createPrimitive.

const char* GUI_PrimitiveHook::getName ( ) const
