[JAVA3D] Rotation about a target

Hello all, I am new to Java and graphic programming, and am trying to rotate the ViewPlatform around a lookat point. I have the correct Matrix4d setup for rotation about the X, Y and Z axis but don't know how to use it in Java3D? The steps I take are: 1) Construct the Matrix4d and initialize i

Hello. I am currently doing something very similar to you (i also have to read vertices from files) and i am using the java.io.StreamTokenizer class to read from files. I hope this helps. - Original Message - From: Sachin Myneni <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday

Re: [JAVA3D] Possible bug

Hello. Thank you for the "hint".     I say this a possible bug because the Sun´s j3d tutorial says that when vertex color is specified the material color is not used.     When you say that without specifying a material the vertex color is mapped correctly, that is true, but that only happens

I am hoping that someone at Sun can help me out... I have developed a program using purely Java3D code. It runs just fine on my machine as either an applet or application. It also runs as on my web page as expected when viewed from my computer. If I then try running it from another computer (a

Re: [JAVA3D] Reading values of type double from a file

Binary data is the fastest way. Class Java.IO.DataOutputStream & java.io.DataInputStream are the best classes to use to store data into your own proprietary format. To share your data with other apps, .3ds file format is one of the most widely used but, complex for beginners. The .obj text format

Re: [JAVA3D] Resetting scene after mouse behaviors

If you move all mouse behaviors into one separate transformGroup then you could use Transform3D t = new Transform3D(); t.set(1, new Vector3d(0.0, 0.0, 0.0)); .setTransform(t); to reset it At 07:36 PM 3/21/00 -0600, you wrote: >Hello, >Is there a way to reset a scene after someon

Re: [JAVA3D] Always Satellite Animation

Hello Olivier, Either: 1) use the unix utility f2c to convert the fortran to C. Some Fortran compilers actually convert to C as a first step of compilation anyway, so it wouldn't be a big problem; or 2) You need a C wrapper to call the Fortran. Basically, compile the Fortran and C separately (

Hi Everyone, I have recently joined this mailing list (and infact recently started using JAVA). I am developing a software which involves a HUGE number of vertices. These vertices are divided into groups. That is, each set represents a plane. Each of these planes have to be transfo

Thanks to all who help me with my problem. The only thing i had to do was install Mesa 3.1 If anyone wants to install Java3d on linux these are the steps: - install jdk (tar xzvf ...) - install java3d (same directory as jdk) (tar xzvf ...) - install Mesa 3.1 (tar xzvf...) (make [linux-386-elf] )

do you mean does Java3D runs on a MacIntosh G4 ? IMHO not yet. Apple hasn't implemented Java3D yet. As Java3D is a system dependend API you cannot run Java3D apps on a system that just supports Java runtime 1.2X. Gernot "BRASSEL Tim (NQ)" <[EMAIL PROTE
