unsigned int osg::BufferObject::addBufferData

(

BufferData *

bd

)

virtual const char* osg::BufferObject::className

(

)

const [inline, virtual]

return the name of the object's class type. Must be defined by derived classes.

Implements osg::Object.

unsigned int osg::BufferObject::computeRequiredBufferSize

(

)

const

static void osg::BufferObject::deleteBufferObject	(	unsigned int	contextID,
		GLuint	globj
	)		[static]

deprecated, provided for backwards compatibility.

BufferData* osg::BufferObject::getBufferData

(

unsigned int

index

)

[inline]

const BufferData* osg::BufferObject::getBufferData

(

unsigned int

index

)

const [inline]

bool osg::BufferObject::getCopyDataAndReleaseGLBufferObject

(

)

const [inline]

Get whether the BufferObject should use a GLBufferObject just for copying the BufferData and release it immmediately.

GLBufferObject* osg::BufferObject::getGLBufferObject

(

unsigned int

contextID

)

const [inline]

unsigned int osg::BufferObject::getNumBufferData

(

)

const [inline]

GLBufferObject* osg::BufferObject::getOrCreateGLBufferObject

(

unsigned int

const [inline]

Get the type of usage the buffer object has been set up for.

virtual bool osg::BufferObject::isSameKindAs

(

const Object *

obj

)

const [inline, virtual]

Reimplemented from osg::Object.

References NULL.

virtual const char* osg::BufferObject::libraryName

(

)

const [inline, virtual]

return the name of the object's library. Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.

Implements osg::Object.

void osg::BufferObject::releaseGLObjects

(

State *

state = 0

)

const [virtual]

If State is non-zero, this function releases OpenGL objects for the specified graphics context. Otherwise, releases OpenGL objects for all graphics contexts.

Reimplemented from osg::Object.

void osg::BufferObject::removeBufferData

(

unsigned int

index

)

void osg::BufferObject::removeBufferData

(

BufferData *

bd

)

virtual void osg::BufferObject::resizeGLObjectBuffers

(

unsigned int

maxSize

)

[virtual]

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::Object.

Reimplemented in osg::PixelDataBufferObject.

void osg::BufferObject::setBufferData	(	unsigned int	index,
		BufferData *	bd
	)

void osg::BufferObject::setCopyDataAndReleaseGLBufferObject

(

bool

copyAndRelease

)

[inline]

Set whether the BufferObject should use a GLBufferObject just for copying the BufferData and release it immmediately so that it may be reused.

void osg::BufferObject::setGLBufferObject	(	unsigned int	contextID,
		GLBufferObject *	glbo
	)		[inline]

void osg::BufferObject::setTarget

(

GLenum

target

)

[inline]

void osg::BufferObject::setUsage

(

GLenum

usage

)

[inline]

Set what type of usage the buffer object will have. Options are: GL_STREAM_DRAW, GL_STREAM_READ, GL_STREAM_COPY, GL_STATIC_DRAW, GL_STATIC_READ, GL_STATIC_COPY, GL_DYNAMIC_DRAW, GL_DYNAMIC_READ, or GL_DYNAMIC_COPY.
