Drishti (from Sanskrit दृष्टि dr̥ṣţi, meaning "vision" or "insight") is a multi-platform, open-source volume-exploration and presentation tool.

"[citation needed] The Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia has used Drishti for a number of purposes, such as volumetric visualisation of various computer-tomography datasets.

The Australian National University (ANU) Physics Department, along with the author of the software, has used it for (amongst other things) the analysis of immiscible flow in massive 3D systems.

Drishti provides a number of features that would otherwise require several proprietary volume visualisation programs or that are simply not available together in other software:
