Re: [JAVA3D] appearance problem

All the capabilities must be set *before* the object is compiled or made live. After that, if you have set the correct capabilities, you can change what ever you want. Cheers, Florin -Original Message- From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED] Behalf Of Madeti, Hen

[JAVA3D] Mapping textures on the inner surface of a sphere

I want to be able to map a texture to the uppermost hemisphere of the inside of a sphere. It's actually a picture of the sky and I'm using a sphere rather than putting it straight on to the background (so that it's not fixed when I move around as is the case when using the background). Being lazy,

Re: [JAVA3D] Mapping textures on the inner surface of a sphere

You have to use the flag GENERATE_NORMALS_INWARD when you create your sphere.

Re: [JAVA3D] Mapping textures on the inner surface of a sphere

Hi Michael, thanks for your message but that's not the problem. I am using the GENERATE_NORMALS_INWARD flag. I can successfully map the texture to the inside of the sphere. My problem is that I only want to map it to the upper hemisphere and not the whole sphere. Cheers, -Paul =

Re: [JAVA3D] appearance problem

Hi Florin and Micheal, thanks for your feedback. I am having problems managing the appearnance dynamically. I have two shape3d's. I wish to turn one shape3d invisible. I plan to do this by setting the rendering attributes to invisible. When i set the capabilities and apply new appearance to one

Re: [JAVA3D] appearance problem

Just a quick thought - Do you have separate Appearance instances for the two shapes? What you are describing would happen if they were in fact sharing the same Appearance instance. Lewis. -Original Message- From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED] On Behalf Of Madet

[JAVA3D] Pics up of Xj3D running on SGI Onyx

A couple of weeks ago I went over to one of our clients at North Dakota State University. The new release of Java3D for IRIX had just been released, so one of the things I did while there was to test out Xj3D on their Onyx/Powerwall combo. It worked with barely any changes (actually, just makefile

Re: [JAVA3D] appearance problem

If you wish to make one Shape3D invisible, I suggest you use a Switch node rather than changing the Appearance. I assume you are setting the transparency attributes to make it invisible. I have had all kinds of problems with transparency, so I would not suggest using it to make objects invisib

just look at Sphere source code at line 100 and change for loop from going to 4 quadrants to 2 ... hack - i agree - but fast Silvère Martin-Michiellot wrote: At 11:03 14/10/2003 +0100, you wrote: Hi Michael, thanks for your message but that's not the problem. I am using the GENERATE_NORMALS_INWAR
