Hi,

I am the beginer of open scene graph, beacause I only want to simulate the parabolic traject of a rugby ball, I do not want to spend many time to learn this complex library. Can some one tell me the most simple way to creat a model of ellipsoid to represent the rugby ball. Thank you very much.


Thank you!

Cheers,
simon

Perhaps OSG is not the best tool for the job, then. OSG is a scene graph library, not a modelling tool or a full 3D environment to simulate stuff in.

You do not "create" a ball in OSG, It doesn't have anything like "draw me an ellipsoid/box/sphere ..." However, it can draw arbitrary meshes. Typically you would make a ball model in something like Blender, 3DS Max or Maya and export the mesh in some format that OSG can read, either the native .osg or some other (.obj, COLLADA, .3ds, etc.).

I suggest that you have a look at some of the tutorials if you want to use OSG for your task - they show how to load models and interact with them.

Regards,

Jan

you might want to find something like a ready 3D model,
say searching in google "rugby ballĀ  model blender" would produce something like http://www.blendswap.com/blends/misc-objects/rugby-ball/ and some more

then, when you grab both blender and a model, you might export this from blender either using osg export pluginĀ  or as 3ds or obj file

then the only thing would be to load the model as a Node.

regards
Sergey
