virtual bool setSize(size_t size)
Sets the size in bytes of the buffer object.
BufferAccessNature getAccessNature() const
Returns the current buffer access nature hint for this buffer object.
BufferAccessFrequency getAccessFrequency() const
Returns the current buffer access frequency hint for this buffer object.
virtual SoBufferObject * createInstance() const
Create a new buffer with the same properties as the current one.
BufferAccessFrequency
Available values for hints on how frequently the application will be changing the buffer's data.
@ STATIC
The application will set the data once.
virtual void clearInstance()
This function clears the content of the buffer, it frees the memory if the mode was COPY.
SoGpuBufferObject(BufferAccessFrequency accessFrequency=STATIC, BufferAccessNature accessNature=SHARED)
Constructor.
BufferAccessNature
Available values for hints on the nature of the application's access to the buffer.
@ SHARED
The application will be writing data to the buffer, but will not read it.
