The Mesh Viewer is an easy to use lightweight application to display triangular meshes from a variety of file formats. It uses the OpenGL API to render the models. The program was born under the need for quickly displaying reconstructed triangulated meshes. The Mesh Viewer based on an idea and an early elementary implementation from Craig Robertson. The current version was developed by Helmut Cantzler. Triangular meshes can be displayed texture mapped (optional with bilinear filtering), solid or as a skeleton (full or just the front lines). The surface normals of the triangles can be displayed optionally. Features (from a different data file) like edges and points can be displayed into the mesh. Loaded models can be rotated, translated and scaled (all done with the mouse). The model is lighted by multiple light sources. Viewpoints can be saved. Screenshots of the model can be taken (as BMP, JPEG, PNG and so on). WWW: http://www.dai.ed.ac.uk/homes/helmutc/mesh_viewer/
