[JAVA3D] Strange Quat4f-behavior!?

2004-02-27 Thread Michael Pfeiffer
Hi, following code-snipped delivers a strange result: System.out.println(Math.toDegrees((new Quat4d(0,Math.toRadians(148),0,1.0)).y)); Instead of 148 the value of y is equal to 57.29577951308232. What happened here? And how can I get the value of 148 out of this quaternion? Michael -- http://www

The result is right. when you create a Quartenion the values are normalized among x,y,z and w. There are some alghoritms in the web to convert a Quaternion to Euler angles (X,Y,Z), but be careful . Some algorithms fails to map the 4D quaternion values to 3D Euler at specific ranges. Of course I a

Hello dude I am a new programmer in J3D. Actually I am busy trying to use file loaders I have some 3D studio image files and I would like to use them in J3D animation. Does anyone can send me a nice example about using loaders for 3D shapes. I'll appreciate any help. Greetings -Original Mess

"The one" example you're looking for doesn't exists. It depends on the loader you use. There is a standard loader interface but not all loaders use it. Some loaders are listed at http://java3d.virtualworlds.de/loader.php On Fri, 27 Feb 2004 17:08:10 +0100, Ghislain DZOU <[EMAIL PROTECTED]> wrote:
