[JAVA3D] 3D on OpenGL

I know, this is probably a stupid question, but still I have to ask it. Is there a way to generate "nice looking" 3D images using Java without having a client-side DLL or SO or whatever extension? I want to send 3D images from my webserver to a client on the internet and as you can imagine, most

[JAVA3D] Mixing OpenGL display lists and Java3D.

Dear all. I have a legacy system 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 the information? Best Regards Magnus

[JAVA3D] Not related question

Hi there, this time it's me to ask something unrelated to Java3D. I want the browser (where my java3d applet is embeded in) to change the page, when the user clicked on a specific object. How can the applet communicate back to the browser? If this is not possible directly, can I use Java Script

Re: [JAVA3D] Bill board transparency, alpha test based...

Wow, I've been fighting depth-sorted transparencies and hadn't thought about this method. I do have some objects that are partially transparent, but the vast majority are just masks. I am now setting my rendering attributes to display if GREATER than 0.5, but the masking doesn't seem to be worki

Re: [JAVA3D] Bill board transparency, alpha test based...

I feel like such a dope. Yep, I got it to work. Only set the RenderingAttributes, not TransparencyAttributes. Just a bug in my code. Range-ordering works, billboarding, lighting. Very nice. What ticks me off more is that I have been fighting for 2 weeks to get range-ordered transparencies go

[JAVA3D] Java3D bloats memory?

I started loading a big VRML97 scene into J3DFly, I discovered that whenever I minimize the application the memory consumption goes to about 50-70 megabytes. But when I maximize it again and moves around a couple of minutes, it quickly reaches 120 megabytes. If I once again minimize J3DFly it inst

Re: [JAVA3D] is this a YUP bug or is it just the code?

If you look a the code you will recognize that the volume data will be put as textures on planes parallel to the x-y, y-z and x-z planes. Depending on your viewpoint the textures will be showed along the x, y, or z axes using the planes parallel to the y-z, x-z or x-y planes respectively. The chan

[JAVA3D] Transparency Faq

In 3d programming there are several different types of blending and transparency which you can use, all with different effects and all with different strengths and weaknesses. Using the alpha channel as a mask is the most efficient since this is done during rasterization and is a simple test which

Re: [JAVA3D] 3D on OpenGL

Dennis, If you want your 3D scenes to move around then you are going to need some respectable CPU power, the DLLs make best use of this. However, if you are going to distribute static 3D scenes then you can do what we did and render your scene to a BufferedImage and use Servlets to distribute t
