We need to look at it in details to see how it could <br>match the MORSE abstractions.<br><br>We plan anyhow to use a standard, ASCII based file format for MORSE <br>simulation assets, and Collada is today the best option.<font class="Apple-style-span" color="#006312"><font class="Apple-style-span" color="#144FAE"><br></font></font></div></blockquote><div><br></div><div>Collada is very mature (and accepted) and supports already many of the things required for robotics. </div><div>Once definitions have been found and approved, we could aim for inclusion in a newer revision of the standard. </div><div>Until then the 'technique' keyword is a good mechanism that preserves compatibility with the standard. </div><br><blockquote type="cite"><div>Very good. Do you plan to port it to Blender 2.5? API have changed a lot </div></blockquote><blockquote type="cite"></blockquote><blockquote type="cite"><div>and Blender 2.4x isn't supported anymore: it would be a pity to loose <br>all the good work you did!<br></div></blockquote><div><br></div><div>Currently, I still cannot estimate how much work it is to port the scripts to Blender 2.5 as it has </div><div>been released very recently and I haven't found the time to look into it deeply. </div><div>I hope that it will be possible, and that it can become an independent component that </div><div>can be integrated into OpenCollada or Blender itself eventually. </div><div>The biggest problem to expect probably is geometry and material data - that part uses still large parts of the </div><div>original import export scripts. The kinematics/armatures part has been completely rewritten. </div><br><blockquote type="cite"><div>Where can we get the source code? do you use VCS that allow easy <br>contribution like git or mercurial? (via Github or Bitbucket?)<br></div></blockquote><div><br></div><div>Being hosted on Sourceforge, you should use SVN to get the latest version </div><div><span class="Apple-style-span" style="font-family: Consolas, 'Deja Vu Sans Mono', 'Bitstream Vera Sans Mono', monospace; font-size: 11px; line-height: 13px; white-space: pre; "><br></span></div><div><span class="Apple-style-span" style="font-family: Consolas, 'Deja Vu Sans Mono', 'Bitstream Vera Sans Mono', monospace; font-size: 11px; line-height: 13px; white-space: pre; ">svn co <a href="https://opengrasp/">https://opengrasp</a>.</span><span class="Apple-style-span" style="font-family: Consolas, 'Deja Vu Sans Mono', 'Bitstream Vera Sans Mono', monospace; font-size: 11px; line-height: 13px; white-space: pre; "><span class="highlighted" style="background-color: rgb(251, 229, 78); ">svn</span></span><span class="Apple-style-span" style="font-family: Consolas, 'Deja Vu Sans Mono', 'Bitstream Vera Sans Mono', monospace; font-size: 11px; line-height: 13px; white-space: pre; ">.sourceforge.net/svnroot/opengrasp/trunk opengrasp</span></div><div><br></div><div>and there is also a mailing-list available at:</div><div><br></div><div><a href="https://lists.sourceforge.net/lists/listinfo/opengrasp-users">https://lists.sourceforge.net/lists/listinfo/opengrasp-users</a></div><div><br></div><blockquote type="cite"><div><blockquote type="cite">* Blender Robot Editor plug-in</blockquote><blockquote type="cite"><br></blockquote><blockquote type="cite">This feature aims to facilitate the creation of robot models for scientific applications. Blender is difficult to master, and the available mechanisms for the definition of kinematics lack a robotics focus. This plug-in lets one build up a kinematic tree and connect it to the geometries in a way that is more familiar to robotic scientists. Together with the powerful modeling capabilities and the various option for importing geometries that blender offers, this plug-in helps to easily create robot models usable in Simulation.<br></blockquote><blockquote type="cite">the import and export of COLLADA v1.5 is currently tightly coupled with this plug-in. Currently, it runs only on blender 2.48/2.49.<br></blockquote><br>This sounds very interesting as well. On the website, it's a bit <br>difficult to understand how it work. Cold you put some videos to better <br>understand?<br></div></blockquote><div><br></div>There is a (little outdated) tutorial in the wiki (<a href="http://sourceforge.net/apps/mediawiki/opengrasp/index.php?title=Create_a_Collada_1.5_model">http://sourceforge.net/apps/mediawiki/opengrasp/index.php?title=Create_a_Collada_1.5_model</a>)</div><div>But I do have a video tutorial from a presentation that I can upload soon (after having added some voice).</div><div><br><blockquote type="cite"><div>And same question: do you plan to port it to Blender 2.5 ?<br></div></blockquote><div><br></div><div>Yes, this would be very helpful indeed. But I fear that this could turn out much more complicated. I have heard that designing plugin guis changed a lot. </div><br><blockquote type="cite"><div><blockquote type="cite">It's important that you are aware that this a work still on development and in a beta state. You are more than welcome to download, test , use it, and contribute to its development. We will still be pushing on its development and the feedback from users and collaborators can be of interest for all of us.<br></blockquote><blockquote type="cite"><br></blockquote><blockquote type="cite">Of course, we are open to establish future collaborations.<br></blockquote><br>It's definitely something we would support!<br>Maybe we should organize an "OpenGrasp/OpenRave - MORSE" event to <br>present the work we did on both side, and see where we can cooperate <br>(definition of standards, libraries of assets, ...)<br></div></blockquote><div><br></div><div>Sounds great! This definitively would be very interesting and helpful.</div><div><br></div><div>Best regards and happy Easter!</div><div><br></div><div>Stefan</div><br></div><br><div>
