ruby-processing and GLTexture
Oct 19th, 2009, 1:43pm  
Hi, i am trying to use the GLTexture library for processing (can't post link) with ruby-processing but i just can't get it right. Is it even possible?
I have tried dropping the jar in the library catalog of ruby processing and importing it via a billion different combinations of load_library, load_java_library, import and require but no luck.
Plz help, i'm going crazy Smiley

Hi Mart.

It's certainly possible to use the GLTexture library from Ruby-Processing. Here's a ported version of Andreas' Basic Use example. If you drop it in the BasicUse folder in the GLTexture examples (so that it has access to its data folder), this sketch will run just fine:

The part that probably tripped you up is needing to explicitly import the GLTexture classes that you're going to use -- a necessary aspect of JRuby's current Java integration.

Cheers,

update: Managed to load GLTexture lib by putting the gltexture.jar  in a catalog named gltexture in library. Thanks Jeremy
