Hi Tirumalesh, The best you can do is do the cutting visually down on the GPU using osg::ClipPlane/osg::ClipNode, see the osgclip example.
The OSG itself its a geometry toolkit, it just has a few basic geometry operations, but its primarily a scene graph for rendering. I'd recommend looking for other toolkits for geometry work. Robert. On 10/19/06, TIRUMALESH CHINTAMANI <[EMAIL PROTECTED]> wrote:
Hi all, I am working on to generate some Geometry shapes by cutting a Object for example a cube to get rectangle,triangle etc.. And there is no way i can construct geometry shapes using osg and also told by Mr.Robert Message: 23 Date: Tue, 17 Oct 2006 09:53:36 +0100 From: "Robert Osfield" <[EMAIL PROTECTED] > Subject: Re: [osg-users] regarding generating geometry shapes To: "osg users" <[email protected] > Message-ID: < [EMAIL PROTECTED]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi Tirumalesh, It sounds like you after constructive solid geometry operations. The OSG doesn't have these, with its focus being rendering rather than modelling. Robert But is it possible, when i use a plane to cut...i mean not physically cutting..just when it passes thru a solid object..i can grab the intersection points of a plane with solid(Ex.Cube) and then using these intersection points, draw a subgraph object on to the scene? Plese pass on some suggestions/ideas regarding this problem. Thank you regards Tirumalesh Chintamani _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
