Member Data Documentation

◆ ignore_volume

std::function<bool(const DS &, volume_descriptor)> GraphicsSceneOptionsWithVolumes::ignore_volume

std::function that returns true if the given volume must be ignored, false otherwise.

Returns false by default.

◆ is_volume_colored

std::function<bool(const DS &, volume_descriptor)> GraphicsSceneOptionsWithVolumes::is_volume_colored

std::function that returns true if the given volume is colored, false otherwise.

For non colored volumes, this is the role of the user of a graphic scene to decide which color must be used (cf. for example Basic_viewer, faces_mono_color). Returns false by default.

◆ is_volume_wireframe

std::function<bool(const DS &, volume_descriptor)> GraphicsSceneOptionsWithVolumes::is_volume_wireframe

std::function that returns true if the given volume is in wireframe, false otherwise.

Returns false by default.

◆ volume_color

std::function<CGAL::IO::Color(const DS &, volume_descriptor)> GraphicsSceneOptionsWithVolumes::volume_color

std::function that returns the color of the given volume, i.e.

the color of all the faces of this volume. nullptr by default.
