virtual void clearInstance()
This function clears the content of the buffer, it frees the memory if the mode was COPY.
SoCpuBufferObject()
Default constructor.
SoCpuBufferObject(void *buffer, size_t size)
Constructor that takes an existing block of CPU memory.
void setBuffer(void *buffer, size_t size)
Request that the buffer object manage an existing block of memory.
virtual SoBufferObject * createInstance() const
Create a new buffer with the same properties as the current one.
