Member Function Documentation

createShadowMaps()

void PBRDemo::createShadowMaps ( ShadowMode  mode )

private

Create shadow maps for the current scene, for a given mode.

Parameters

mode	the shadow type to prepare for when creating the shadow maps

draw()

void PBRDemo::draw ( )

overridevirtual

Draw call.

Implements Application.

physics()

void PBRDemo::physics ( double  fullTime, double  frameTime  )

overridevirtual
