Category: New IO Format Group: None Status: Open Priority: 5 Private: No Submitted By: Robert Lancashire (rjlanc) Assigned to: Nobody/Anonymous (nobody) Summary: Collada 3D format Initial Comment: Sun's Project Wonderland is an Open Source project to create an immersive on-line environment that can be used for meetings or teaching purposes etc. Modules can be imported into the on-line worlds in KMZ/DAE Collada formats. These 3D formats are Open Source arrangements that have been incorporated into many 3D packages and support textures/surfaces etc. Since these Collada formats seem to be the XML replacement to VRML, it would be useful to have Jmol export in this format. Details of the schema are available from www.collada.org ---------------------------------------------------------------------- >Comment By: Robert Lancashire (rjlanc) Date: 2009-06-05 16:14 Message: Angel, we too have struggled to come to grips with the 500+ pages of their manual !! We have looked at Blender (blender.org) and Google Sketchup for software to generate 3D data and found some "simple" example files in the Google 3D warehouse. The free Sketchup does not export a Collada file but if you upload to their warehouse they convert it overnight. Look for propanone or benzene for example. The manual suggests it is possible to have a sphere and cylinder but all the sample files I've found contain hundreds of vertex data points instead. This may be OK for JVXL but for a simple molecule with 10 atoms having to generate thousands of data points would be a real pain.... For VRML you define a macro to generate these I gather but for Collada you have to write them all out it seems! ---------------------------------------------------------------------- Comment By: Angel Herraez (aherraez) Date: 2009-06-05 15:21 Message: Robert, as I did some work on the existing implementation of VRML export, and played a bit with X3D export, I'd be rather interested on this. However, the official doc does not give me enough clues as to what the format must be (it's way too complex). We need to focus on the minimal framework of the DAE file format and on the specs for spheres and cylinders. Also, I'd need a simple DAE viewer for testing. I've tried ColladaLoader but it does not run in my system (seems to be due to need of OpenGL which by PCs don't support). I found SwirlViewer which seem to work, but I have been unable to write a test DAE file that displays in it. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=379136&aid=2800827&group_id=23629 ------------------------------------------------------------------------------ OpenSolaris 2009.06 is a cutting edge operating system for enterprises looking to deploy the next generation of Solaris that includes the latest innovations from Sun and the OpenSource community.
