Detailed Description

class HUtilityAntialiasing

The HUtilityAntialiasing class contains a set of function for software based image antialiasing.

This class provides support for rendering an antialiased scene. This is achieved by rendering the scene to an image that is large then the extents of the view on the screen.

Public Functions

~HUtilityAntialiasing()

bool GetShowState(): Returns Whether antialiased picture is currently displayed

bool CreateImage()

Creates Antialiased Image in memory buffer

Returns:	A boolean indicating success or failure

void Show(int factor = 4)

Create and Display antialiased image

Parameters:	factor – oversampling factor

void Hide(): Hide antialiased picture
