Volume Renderer

This page is under construction.

Introduction

The volumetric display of large datasets is a challenging task for medical imaging and visualization because of high memory requirements set by 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 rendering is shown in the figure below.

System Requirements

For system requirements, refer to MIPAV system requirements - GPU computing page.
