bezier tweening
Feb 1st, 2010, 10:38am  
has anyone seen examples doing bezier tweening using the bezier methods (bezier, bezierPoint, bezierTangent, etc..)? ive seen some using as3 but wanted to see if there was something in java... what i wanted to do is make a method similar to toxis spline2d and 3d methods which takes a list of points and makes the control points so that a curved path is drawn through them...

Hi ekenei,

http://en.wikipedia.org/wiki/B%C3%A9zier_curve
look at how bezier works on wikipedia, see the Constructing Bézier curves section.

also

that page may interest you cause it shows a bezier example in opengl
here is the link http://gritche.perso.libertysurf.fr/OpenGL/Bezier.html

ill keep searching

also, if you want some 3D bezier, i think you need to know more about NURBS. anyways, if i find you something really helpfull, ill post it.

thanks bloom. it took me a day or two... but i found how to do it using different interpolation types! so ill be posting some new changes to the tween library with a path tweening class/method which has 3-4 different modes and takes an array of points . im also going to release the 2d and 3d path classes as part of a core library im making which will be required to the path tweening functions...
