Member Function Documentation

◆ computeShadowVolumeInformationCPU()

void H3D::ShadowTransform::computeShadowVolumeInformationCPU	(	const LightDataStruct &	light_data,
		Matrix4f	accumulated_fwd,
		bool	render_caps,
		std::vector< Vec4d > &	coord
	)

virtual

Override to compute the shadow volume information of this object for light used in shadow caster single buffer mode.

Parameters

light_data	A struct containing information about the light that is creating the shadows.
accumulated_fwd	The accumulated forward matrix.
render_caps	determines if one should draw end caps to the volume or if it is ok to leave it open.
coord	contains the coords.

Implements H3D::H3DShadowObjectNode.

◆ renderShadowGPU()

void H3D::ShadowTransform::renderShadowGPU	(	const LightDataStruct &	light_data,
		Matrix4f	accumulated_fwd,
		bool	render_caps
	)

virtual

Override to do implement shadows using a geometry shader.

Parameters

light_data	A struct containing information about the light that is creating the shadows.
accumulated_fwd	The accumulated forward matrix.
render_caps	determines if one should draw end caps to the volume or if it is ok to leave it open.

Implements H3D::H3DShadowObjectNode.

◆ update()

void H3D::ShadowTransform::update ( )

virtual

Traverse into the ShadowTransform and through into any shadow volumes, preparing them for rendering.

This is called by shadow caster
