Re: [JAVA3D] making an object(s) "disappear"

Hi, You can also add RenderingAttributes to the Appearance of the objects (using the setRenderingAttributes method of Appearance), then use the setVisible method of RenderingAttributes to show/hide the objects. Mona Wong wrote: > Hi: > > I'm sure this must be documented somewhere but I

[JAVA3D] FW: [JAVA3D] making an object(s) "disappear"

You can do No.1 or No.3 No.2 could work but is not a good idea speciall if there are other objects behind it. then chaning the color to background color wont help No.3 will work if u have the object(s) in your branch group u have to Detach the BranchGroup and remove the objects then Attach the

[JAVA3D] making an object(s) "disappear"

Hi: I'm sure this must be documented somewhere but I have not been able to find the answer, especially with j3d.org down ... I have several 3d objects in my canvas and I want to allow the user to turn off display of any object(s) s/he chooses. I can see several ways of doing thi

Dan, Yup... my code works FINE with only a single link to the SG. My code was used successfully for a project last year. Can you tell me what is wrong with this code: TransformGroup bushes = new TransformGroup(); Vector3f translate = new Vector3f(); Transform3D T3D = ne

Re: [JAVA3D] Oriented Shape3Ds in Shared Groups

Dan, Bringing my OrientedShape3D code into your example works just fine. What concerns me (and makes this difficult to test) is that you are using a dramatically different way of moving the viewing platform. You use: rotate.setTransformGroup(viewingPlatform.getMultiTransformGroup().getTransform

Re: [JAVA3D] Calling OpenGL in native code.

We currently do not allow applications to make low level api calls directly. The only way to "decompile" an OpenGL display list is to render it in feedback mode. We are looking at some ways to gain access to low level API contexts in Java 3D 1.4 Your best bet is to find a way for the native cod

Re: [JAVA3D] Java3D Version at runtime

You need to make sure that at least one of the classes has been loaded from the package before you call getPackage. Check out the PackageInfo example program (in /demo/java3d/PackageInfo). Btw, in version 1.3, we are adding explicit version info. See VirtualUniverse.getProperties(). -- Kevin R

Re: [JAVA3D] Object Tansparancy

I'm not sure I totally understand the effect you are after, but I'll take a stab. You are making the objects totally transparent, but you want the texture on the object to show up, and expecting the texture to be completely opaque. The texture REPLACE mode can be a little deceiving. Reading fro

[JAVA3D] Calling OpenGL in native code.

Dear all. I am uncertain if this ever made it to the list so I am rephrasing it and posting it again. I have native code which manipulates OpenGL display lists. Is there a way to incorporate a display list into any of the Java3D objects? Or is there a way to decompile the display list and use t

hello. i'm making transparent 3D objects in 3D space using texture . what i did was - set the material transparant, and set the texture opaque. The result was, the object is opaque to the background, but transparent to the other objects. the background is hidden behind the object, but i can se
