PostProcessEffectsControl

class HPS.PostProcessEffectsControl : public HPS.Control 

The HPS.PostProcessEffectsControl class is a smart pointer that is tied to a database object. This object is effective only for the shader-based driver interfaces such as DirectX and OpenGL2. Ambient occlusion, bloom, silhouette edges, and depth of field are all enabled through this control. Default values for the various fields of HPS.PostProcessEffectsControl can be found here.

Public Functions

override void Dispose ()

override HPS.Type ObjectType ()

This function returns the type the object, as declared (if the object is derived, this does not give the true type of the derived object).

Return: The declared type of the object in question, which may differ from the true, underlying type.

PostProcessEffectsControl (HPS.PostProcessEffectsControl in_that): Initializes a control tied to the same object as in_that.

PostProcessEffectsControl (HPS.WindowKey in_seg): Initializes a control tied to the window segment in_seg.

HPS.PostProcessEffectsControl SetAmbientOcclusion (bool in_state)

Ambient occlusion is a general term for shading that varies when nearby objects (occluders) would prevent some portion of ambient light from reaching a surface. This applies a filter that looks for small valleys in the depth buffer results, and slightly darkens these areas.

Note

Ambient occlusion uses the depth buffer that is generated when we render opaque geometry to approximate ambient occlusion. Drawing of transparent geometry is always deferred until after all opaque geometry is drawn, and doesn’t write any depth information to the depth buffer. Thus, transparent geometry will effectively not exist for ambient occlusion calculations, and will therefore be unaffected by them. This also means that if all geometry in a scene is transparent, ambient occlusion is effectively disabled.

Param in_state: Whether ambient occlusion should be used.
Return: A reference to this object.
