osg.Drawable¶

class osg.Drawable¶

Represents:	c++ class
Wraps:	osg::Drawable
Bases:	osg.Node

Methods:

:asGeometry()¶

Return type:	osg.Geometry

:getOrCreateStateSet()¶

Return type:	osg.StateSet

:getStateSet()¶

Return type:	osg.StateSet

:setStateSet(osg.StateSet ss)¶

Parameters:	ss (osg.StateSet) –

:removeStateSet()¶

:setUseDisplayList(bool b)¶

Parameters:	b (bool) – When set to true, force the draw method to use OpenGL Display List for rendering. If false, rendering directly. If the display list has not been compiled already, the next call to draw will automatically create the display list.

:getUseDisplayList()¶

Return whether OpenGL display lists are being used for rendering.

Return type:	bool

:setUseVertexBufferObjects(bool b)¶

Parameters:	b (bool) – When set to true, ignore the osg.Drawable.setUseDisplayList() settings, and hints to the drawImplementation() method to use OpenGL vertex buffer objects for rendering.

:getUseVertexBufferObjects()¶

Return whether OpenGL vertex buffer objects should be used when supported by OpenGL driver.

Return type:	bool

:setUseVertexArrayObject(bool b)¶

Set whether to use a local VertexArrayObject for this Drawable.

Parameters:	b (bool) –

:getUseVertexArrayObject()¶

Return whether to use a local VertexArrayObject for this Drawable.

Return type:	bool

:dirtyDisplayList()¶

Deprecated, use osg.Drawable.dirtyGLObjects() instead.

:dirtyGLObjects()¶

Force a recompile on next osg.Drawable.draw() of any OpenGL objects associated with this geoset.

:getGLObjectSizeHint()¶

Return the estimated size of GLObjects (display lists/vertex buffer objects) that are associated with this drawable. This size is used a hint for reuse of deleted display lists/vertex buffer objects.

Return type:	unsigned

:getNumParents()¶

Return type:	unsigned

:getParent(unsigned i)¶

Parameters:	i (unsigned) –
Return type:	osg.Node

:getInitialBound()¶

Get the initial bounding volume to use when computing the overall bounding volume.

Return type:	osg.BoundingBox

:setInitialBound(osg.BoundingBox bound)¶

Set the initial bounding volume to use when computing the overall bounding volume.

Parameters:	bound (osg.BoundingBox) –

:getBoundingBox()¶

Get BoundingBox of Drawable. If the BoundingBox is not up to date then its updated via an internal call to osg.Drawable.computeBound().

Return type:	osg.BoundingBox

:computeBoundingBox()¶

Compute the bounding box around Drawables’s geometry.

Return type:	osg.BoundingBox

:setShape(osg.Shape shape)¶

Set the Shape of the Drawable. The shape can be used to speed up collision detection or as a guide for procedural geometry generation.

Parameters:	shape (osg.Shape) –

:getShape()¶

Get the Shape of the Drawable

Return type:	osg.Shape
