Drishti Description

Drishti is a simple, easy to use application specially designed to offer you a volume renderer. Drishti stands for vision or insight in Sanskrit, an Indian language. Drishti has been developed keeping in mind the end-use : visualizing tomography data, electron-microscopy data, etc. Understanding the data set is important and conveying that understanding to the research community or a lay person is equally important. Drishti is aiming for both. The central idea about Drishti is that the scientists should be able to use it for exploring volumetric datasets as well as use it in presentations. Main features: Data Sets: Large volumes (10243 regularly explored) Two same sized volumes together Volumetric time-series Loads image stacks - including DICOM images Classification / Segmentation: Two-dimensional transfer functions Transfer function sets for various purposes Region growing using user provided seeds Animation: Transfer function animation Sub volume animation Overlapping subvolume possible Each subvolume can have its own transfer function set Time-series animation Camera path Clip plane animation Streamline animation Vector Data Sets: Interactive Streamline generation and rendering Rendering and Shading: User defined glsl-shader scripts for rendering and shadowing User controlled quality of rendering to suit GPU capability User controlled lighting - control lighting with transfer functions Self shadowing and Subsurface Scattering for volumetric objects. Shadows using FrameBufferObject when ever possible Reverts to RenderToTexture if not. Works on Mac and Linux Back Lighting Different transfer functions can be blended from back to front Emissive Color Tools: Inbuilt help Extract data from netCDF files Graphical interface for downscaling volumes Cropping and scaling for image stacks Cropping and scaling for RAW volumes Place markers directly on volume data Volume masks Volume estimation Enclosing surfaces Tensor visualization with superellipsoids Network (Graph) visualization Distance measurements Legend display Caption Editor Slices Clip planes Screen Lens Stereo viewing Polhemus tracker enabled for VR setup Preset camera positions Display of actual voxel values User defined triangular mesh vSaving Movies VizNotes facility : Provides a journal like facility which can store images along with text in an xml or html file.
