Stable versions now available for download at google code.

Drishti interface and engine has been rewritten using QT with an aim towards presenting a better user experience.

Ancient version

Drishti-0.1.8 is still available.

Features

Drishti comes with 5 modules - Renderer, Prithvi, Import, Paint, Composite.

Graphics Hardware Requirements

Only the Renderer and Prithvi module needs high-end graphics cards, the others can do without one. Development of Renderer and Prithvi has being done on NVIDIA Quadro FX 1000. Both the modules should work on any NVIDIA card from FX 5200 and above. The programs should also work on any GPU supporting OpenGL 2.0 feature set (NVIDIA/ATI/3DLabs/...).


Import

Import utility converts the volume files from users' own format into the format that Drishti 3d Renderer understands - i.e. .pvl.nc (NetCDF format).


Paint

Paint utility is helpful in generating/modifying the masking information for volumes.


Composite

Composite utility is helpful in touching up/modifying the already generated images.
