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_dataA struct containing information about the light that is creating the shadows.
accumulated_fwdThe accumulated forward matrix.
render_capsdetermines if one should draw end caps to the volume or if it is ok to leave it open.
coordcontains 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_dataA struct containing information about the light that is creating the shadows.
accumulated_fwdThe accumulated forward matrix.
render_capsdetermines 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

Reimplemented from H3D::H3DShadowObjectNode.
