Re: [osg-users] How to compute the coordinates of specific point ?
Well thank you Shayne, I understand now, my problem is supposed to be much simplier than handling a *collision detection. *so don't bother yourself with my code snippet, it is just newbie attempt have a nice day* ** * *--* *Mohamed ALJI* Élève ingénieur en Informatique troisième année à l'ENSEIRB-MATMECA (Institut Polytechnique de Bordeaux - IPB) Webmaster bénévole de l'association L'eau du désert: www.l-eau-du-desert.com ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] How to compute the coordinates of specific point ?
okey, having loaded a 3d model like this image [image: Aqua-Table-by-Zaha-Hadid-for-Established-Sons-1.jpg] I would like to find a way to compute the bottom point of this object ?

Do you have a code snippet you can show us on how you're currently using this model for collision detection? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=37156#37156 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi, sorry for sending a one-liner and being so blunt... I think you will get more help if you read up a bit on transformations and then ask your question again with more detail provided. rgds jp On 24/02/11 11:48, Mr Alji wrote: Thank you for answering, not really what I am looking for but it already helped ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.
