...The process goes through the list of triangles that make up the surface and, for each triangle, forms a tetrahedron with an external point. The program uses the origin (0,0,0). The volume of the tetrahedron is then calculated. Tetrahedrons with back facing triangles are added and those with forward facing triangles are subtracted yielding the object volume. A detailed description of the process is presented in the ObjectVolumeTutorial.doc document as well as program logic and results. A key component in the program is a subroutine that calculates the volume of a tetrahedron. ...

GIMP Plug-In set for 360° panoramas =================================== This plugin set contain 4 plugins helpful in 360° equirectangular panorama creation: * fill_zenith_nadir - fills transparent areas on the top and the bottom of the generated panorama with a gradient that smoothly connects to the neighbour pixels * panorama_to_zenith_nadir - converts panorama to editable form of zenith and nadir areas.

Take a 2D flat photo... and turn it into a w3D "wiggle stereogram"! INSTANTLY! Wiggle stereograms use animation to switch between the left and right view of a stereogram. Here we create a nice animation that slides back and forth, for a smooth wiggle 3D ("w3D") effect. First the image is broken down into planes. Each plane is given a depth distance. The image belonging to each plane is horizontally compressed enough that the "shadows" cast by the image belonging to the planes in front of it cover the "holes" in the plane. The whole thing is then animated in a gentle see-saw fashion to get the wiggle effect. ...
