Member Function Documentation

◆ availableDrawModes()

DrawModes::DrawMode ACG::SceneGraph::BoxesNode::availableDrawModes ( ) const
inlineoverridevirtual

Return a list of available draw modes for this node: should be OR'ed from the items of the enum DrawModeIDs.

Reimplemented from ACG::SceneGraph::BaseNode.

Definition at line 70 of file BoxesNode.hh.

◆ boundingBox()

void ACG::SceneGraph::BoxesNode::boundingBox ( Vec3d ,
Vec3d  
)
overridevirtual

Compute the bounding box of this node and update the values _bbMin and _bbMax accordingly. Do not initialize _bbMin and _bbMax since they may already store values of previous nodes' bounding box computation.

Reimplemented from ACG::SceneGraph::BaseNode.

Definition at line 103 of file BoxesNode.cc.

◆ getRenderObjects()

void ACG::SceneGraph::BoxesNode::getRenderObjects ( IRenderer _renderer,
GLState _state,
const DrawModes::DrawMode _drawMode,
const ACG::SceneGraph::Material _mat 
)
overridevirtual

Deferred draw call with shader based renderer.

The renderer calls this function to collect the geometry that should be rendered from the nodes.

Add any renderable geometry to the renderer via _renderer->addRenderObject()

The material is fetched from the last active material node and may be used to setup Renderobjects, but may as well be ignored.

Note
You should not draw anything yourself in this function.
Parameters
_rendererThe renderer which will be used. Add your geometry into this class
_stateThe current GL State when this object is called
_drawModeThe active draw mode
_matCurrent material

Reimplemented from ACG::SceneGraph::BaseNode.
