Dear visitor:

This package is no longer maintained. Its usable contents have long ago migrated to Meshing and MeshIO. The remaining bit of code related to mesh simplification had not yet found its way into another package at the time of this writing, but I don't believe it ever worked correctly, anyway. Still, it might serve as a starting point for a correct implementation. After all, I based it on a correct C++ implementation that I had created previously.

Sincerely, Tracy Wadleigh, original author.

Meshes.jl

This package is designed to make it easy to work with polygon mesh data. It is a primarily a meta-package for Meshing, MeshIO, and GeometryTypes. In addition, it is a great (and recommended) place for experimental development that is not yet congruent with the GeometryTypes type heirarchy.

The current release series corresponds to v0.2.x. The pre-GeometryTypes, et. al. version, v0.1.x, is still supported by @sjkelly.

Data Types

Meshes does not define many datatypes, but rather it uses those defined by GeometryTypes where possible.

Functionality

Meshing

This functionality is derived from the Meshing package. Full documentation is available there. In combination with GeometryTypes it is easy to mesh implicit functions.

using Meshes
using GeometryTypes

s = SignedDistanceField(HyperRectangle(Vec(0,0,0.),Vec(1,1,1.))) do v
           sqrt(sum(dot(v,v))) - 1 # sphere
       end
m = HomogenousMesh(s) # uses Marching Tetrahedra from Meshing.jl
save("eighth_sphere.ply",m)

Files

Meshes v0.2.0 and up depends on the Julia FileIO framework in order to load files. This is re-exported from FileIO.

using Meshes
m = load("my3dmodel.obj")
save("my3dmodel_now_a.ply", m)

History

This package started with an exclusive focus on Mesh geometry. For the first year of existence it worked exclusively for computational geometry purposes. In early 2015 an effort started to generalize for compatibilty with display libraries such as OpenGL. This meant redesigning types and operations. Ultimately it was broken up into other packages to facilitate collaboration. Most notably Meshing, MeshIO, and GeometryTypes contain a significant portion of the original code. We plan to support this package as a meta-package for domain focused usability and extensions.
