	One of the major challenges in instrument control is to provide a fast and scientifically correct representation of the data collected by the detector through the data acquisition system. Despite the availability nowadays of a large number of excellent libraries for off-line data plotting, the real-time 2D and 3D data rendering still suffers of performance issues related namely to the amount of information to be displayed. The current paper describes new methods of image generation (rendering) based on JOGL library used for data acquisition at the Institut Laue-Langevin (ILL) on instruments that require either high image resolution or large number of images rendered at the same time. These new methods involve the definition of data buffers and the usage of the GPU memory, technique known as Vertex Buffer Object (VBO). Implementation of different modes of rendering, on-screen and off-screen, will be also detailed.
