This method contains the OpenGL rendering code for the shadowmap. This code is called internally by CHAI3D. Do not call this method directly.

Parameters

a_options Rendering options.

bool chai3d::cShadowMap::updateMap	(	cWorld *	a_world,
		const cVector3d &	a_lightPos,
		const cVector3d &	a_lightLookat,
		const cVector3d &	a_lightUp,
		const double	a_lightFieldViewAngle,
		const double	a_distanceNear,
		const double	a_distanceFar,
		const double	a_mirrorH,
		const double	a_mirrorV
	)

This method creates a shadow map by providing a world and view point information.

Parameters

a_world	World in which to create shadow
a_lightPos	Position of eye.
a_lightLookat	Eye lookat position
a_lightUp	Eye orientation (up vector).
a_lightFieldViewAngle	Field of view of light source
a_distanceNear	Distance to near clipping plane.
a_distanceFar	Distance to far clipping plane.
a_mirrorH	Scale factor for horizontal mirroring (-1.0 or 1.0)
a_mirrorV	Scale factor for vertical mirroring (-1.0 or 1.0)

Returns: true if shadow map was created successfully. false otherwise.
