Built using Kitware's VES library, KiwiViewer is a free, open-source visualization app for exploring scientific and medical datasets. KiwiViewer opens a variety of file formats including obj, stl, ply, vtk, vtp, vtu, vti, mha, g, and pdb. Datasets can be opened from the SD card or DropBox, or downloaded from a URL. Scenes consisting of multiple datasets can be loaded into KiwiViewer using a simple comma-separated-value file format.
