Detailed Description

This object represent a general class of pixel buffer objects, which are capable of allocating buffer object (memory) on the GPU. The memory can then be used either for CPU-GPU pixel transfer or directly for GPU-GPU transfer, without CPU intervention.

Member Function Documentation

virtual void osg::PixelDataBufferObject::bindBufferInReadMode ( State state)
virtual

Bind the buffer in read mode, which means that data can be downloaded from the buffer (note: GL_PIXEL_UNPACK_BUFFER_ARB)

virtual void osg::PixelDataBufferObject::bindBufferInWriteMode ( State state)
virtual

Bind the buffer in write mode, which means following OpenGL instructions will write data into the buffer (note: GL_PIXEL_PACK_BUFFER_ARB)

virtual void osg::PixelDataBufferObject::compileBuffer ( State state) const
virtual

Compile the buffer (reallocate the memory if buffer is dirty)

unsigned int osg::PixelDataBufferObject::getDataSize ( ) const
inline

Get data size of the used buffer.

Definition at line 692 of file BufferObject.h.

Mode osg::PixelDataBufferObject::getMode ( unsigned int  contextID) const
inline

Definition at line 721 of file BufferObject.h.

osg::PixelDataBufferObject::META_Object ( osg  ,
PixelDataBufferObject   
)
virtual void osg::PixelDataBufferObject::resizeGLObjectBuffers ( unsigned int  maxSize)
virtual

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::BufferObject.

void osg::PixelDataBufferObject::setDataSize ( unsigned int  size)
inline

Set new size of the buffer object. This will reallocate the memory on the next compile.

Definition at line 689 of file BufferObject.h.

virtual void osg::PixelDataBufferObject::unbindBuffer ( unsigned int  contextID) const
virtual

Unbind the buffer.
