Re: [osg-users] Question about osgAnimation Bezier curves

Hi arjdan, You are making mistakes on the computation of the ControlPoint In the ControlPoint Out of the Bezier Curve. Assume you have several points (knots) and that your path will pass throw some points V(i), the Vec3 CubicBezier Keyframe are calculated as follow : the p is your V(i), but

Re: [osg-users] Question about osgAnimation Bezier curves

Hi, I've these points: v[0] = osg::Vec3d( -19, 0, -60); v[1] = osg::Vec3d( -20, 0, -102); v[2] = osg::Vec3d( -22, 0, -145); v[3] = osg::Vec3d( 20, 0, -142); v[4] = osg::Vec3d( 63, 0, -139); v[5] = osg::Vec3d( 145, 0, -138); Points v[1],

Re: [osg-users] Question about osgAnimation Bezier curves

Ok, thank you, I've understood how cubic bezier works. I've another question: I notice that the ball stops when it reachs every point. Is there a simple way to make a continuous animations, without stops? -- Read this topic online here:

Re: [osg-users] Question about osgAnimation Bezier curves

Hi, p is point i is control point in o is control point out You maybe interested to look in file include/osgAnimation/BezierCubic and include/osgAnimation/Interpolator It's where the bezier code are located Cheers, Cedric On Mon, 2010-07-05 at 09:35 +, daniele argiolas wrote: What are p,

[osg-users] Question about osgAnimation Bezier curves

Hi, I try to understand and modify osg example osganimationmakepath. I want to realize a simple path like the figure. I've the keyframes keys-push_back(osgAnimation::Vec3CubicBezierKeyframe(0, osgAnimation::Vec3CubicBezier(v[0],v[1],v[1])
