small tool is designed for fast generating 3D tetrahedral/vox mesh out
of the complex input surface geometry (in obj format). For many
graphics/simulation research, obtaining the high quality volumetric
mesh is a quite headache especially for complex structural models. This
piece of small tool generates the tetrahedron based on the voxlization
of the input obj based on the idea of Squashing
Cubes with much easiler implementation. Each vox is
then divided into 6 tetrahedrons and the output is .ele/.node file
which are one of the standard output of Tetgen.
the obj, please scale the mesh before do any further selection to
normalize the input obj into 1 by 1 by 1 standard cube. Pressing 'S' to
enter selection mode and select region with right button of your mouse.
When the selection is done, press 'add to new component' to generate
the tetrahedral mesh corresponding to your selection or 'add to
component' to combine to the last generated component. You may also
save your working status and continue later. A more elegant version is
going to be out shortly. [Binary]
