The volumetric display of large datasets is a challenging task for medical imaging and visualization because of very demanding memory requirements set by the Java Virtual Machine.
MIPAV volume renderer uses a Java3D scene graph-based framework that allows us to implement both the 3D texture-based and raycast-based volume renderers. An image scene graph approach used for volume rendering in MIPAV is shown in the figure on your left.
Main article: MIPAV system requirements - GPU computing
To run Volume Renderer MIPAV uses GPU computing. It requires that an NVIDIA video card and the proper video card driver to be installed on your computer:
Note: if the GPU Computing Enabled option is grayed out in the MIPAV Options - Other dialog box, that means that either a video card driver or a video card needs an upgrade, or they both need it.

Before starting to use Volume Renderer on a regular basis, it is important to make sure that i) your computer has enough memory to run it and ii) a video card and a video card driver are properly installed. For system requirements, refer to the MIPAV system requirements - GPU computing page.
However, even if all system requirements are met, it makes sense to run a simple test (explained below) on Volume Renderer. If steps 2-5 of that test go smoothly, you can use Volume Renderer for your research.
If any of the above steps fail, do the following:
