Member Function Documentation

◆ getAbstractGeometry()

virtual const Core::Geometry::AbstractGeometry& Ra::Engine::Data::Displayable::getAbstractGeometry ( ) const
pure virtual

Returns the underlying AbstractGeometry, which is in fact a TriangleMesh

See also
getTriangleMesh
Todo:
not sure the displayable must have an abstract geometry ...

Implemented in Ra::Engine::Data::VolumeObject, Ra::Engine::Data::CoreGeometryDisplayable< T >, and Ra::Engine::Data::CoreGeometryDisplayable< Core::Geometry::PointCloud >.

◆ render()

virtual void Ra::Engine::Data::Displayable::render ( const ShaderProgram *  prog)
pure virtual

Draw the mesh. Prog is used to set VertexAttribBinding, but it has to be already binded

Implemented in Ra::Engine::Data::VolumeObject, Ra::Engine::Data::MultiIndexedGeometry< T >, Ra::Engine::Data::IndexedGeometry< T >, Ra::Engine::Data::IndexedGeometry< Core::Geometry::TriangleMesh >, Ra::Engine::Data::IndexedGeometry< Core::Geometry::LineMesh >, and Ra::Engine::Data::PointCloud.

◆ updateGL()

virtual void Ra::Engine::Data::Displayable::updateGL ( )
pure virtual

This function is called at the start of the rendering. It will update the necessary openGL buffers.

Implemented in Ra::Engine::Data::AttribArrayDisplayable, Ra::Engine::Data::VolumeObject, Ra::Engine::Data::CoreGeometryDisplayable< T >, and Ra::Engine::Data::CoreGeometryDisplayable< Core::Geometry::PointCloud >.
