Announcing a library that extends toxiclibscore, to allow direct export of mesh objects to PovRAY mesh2

in Library and Tool Development • 1 year ago

The library is available for testing/download here, it is the povmesh.zip library that you wan't to download if you'd like to export TriangleMesh or WETriangleMesh to povray as a mesh2 object (the povwriter.zip library is a more general tool but allows for raytracing from the processing ide). You should probably install the toxicilibs complete to work with this library, but you could get away with toxiclibscore and toxiclibs_p5 but you should also install volumeutils (for its examples). I had been looking for some time for a way of exporting meshes from processing to PovRAY, and rather than start from scratch I've built the functionality on top of the toxiclibscore. The povmesh library, should be somewhat future proof (it was actually complied against a development version of toxiclibs-21 see my blog) unlike my povwriter library that won't run on processing-2.0 ( relies on PGraphics3D which is disappearing).

I have just uploaded a new version of this library which has the following features:-

It no longer conflicts with toxiclibscore (this is important for processing 2.0)
Enhancement, now supports export of an array of toxcilibs meshes to PovRAY mesh2 objects
Enhancement, now has a built in texture generator including Metal, Glass and simple Phong
The original no texture option (RAW) is retained for flexibilty

The requirements and download details as above. New example included is Karstens AlignMesh example, which was the primary driver to support an array of meshes, choose GLASS (transparency) or METAL (opaque) texture options to return a sequence of rainbow colors.

I've further updated this library to support, the assigning different textures to each mesh. As a result the library has been somewhat re-factored. The main differences to the user interface are:-

User needs to supply a File rather than a PrintWriter
Texture declarations are now saved to a separate file "my_texture.inc"
This file should be included before the "geometry.inc" file

As part of the re-factoring I make use of EnumSet, and other enum features which could be of interest to others contemplating using enum switches, and other features. For download see next post.

I have now put the source code of my povmesh library up on github, so you could clone it if you wish:-
I have started the wiki here, which include links to the regular library.zip download (includes src and examples). Tested on linux but should work on Mac and Windows. MeshAlign example features rainbow glass textures.

I' ve just updated my povmesh library to support processing-2.0.

New feature is the ability to use a built in mesh to vbo converter to convert the mesh into a PShape. For purposes of viewing the mesh object I have also included a ArcBall utility (although currently the exported mesh does not reflect the arcball orientation, but I might add this later if I create an ini file writer). Get the library here, read about it here, and a worked example on my blog.
