Member Function Documentation

virtual const char* osg::BufferData::className

(

)

const [inline, virtual]

return the name of the object's class type.

Must be defined by derived classes.

Implements osg::Object.

Reimplemented in osg::DrawElementsUInt, osg::DrawElementsUShort, osg::DrawElementsUByte, osg::DrawArrayLengths, osg::DrawArrays, osg::PrimitiveSet, osg::Image, osg::Array, osg::ImageSequence, and osg::ImageStream.

void osg::BufferData::dirty

(

)

[inline]

Dirty the primitive, which increments the modified count, to force buffer objects to update.

If a ModifiedCallback is attached to this BufferData then the callback is called prior to the bufferObject's dirty is called.

virtual const char* osg::BufferData::libraryName

(

)

const [inline, virtual]

return the name of the object's library.

void osg::BufferData::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.

virtual void osg::BufferData::resizeGLObjectBuffers

(

unsigned int

maxSize

)

[virtual]

Resize any per context GLObject buffers to specified size.
