[JAVA3D] quad array = blue screen?!?!

2002-06-22 Thread Zaki Alam
I just switched from using a large TriangleArray to a QuadArray and I'm getting blue-screened on WinXP/j3d 1.3b1/direct3d8.1/nvidia gforce2mx (latest drivers). I'm aware that older direct3d versions don't support quadarrays, but I assumed that I'd just get software rendering. ... works fine unde

[JAVA3D] Multiple Display System Using Linux, J3D, and Multiple PCs

Hi,   I am trying to set up a system using several networked PCs running Linux, each with their own OpenGL graphics accelerator.  I have searched near and far for such an example, but have been unsuccessful.  Anyone using such a system?  How are the displays coordinated over the network?  Ha

Our primary trick is to use GIFs so that we can use four times as many textures as otherwise. Also trying to make sure we use as small as possible of textures (and letting them tile or stretch). Multitexturing is certainly a good trick. Dynamically loading textures as you travel to different are

Wow, so how do you avoid having your scenes look repetituve and bland? Multitexturing? I thought that would be worse than what I'm doing. - Original Message - From: "John Wright" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, June 22, 2002 1:03 PM Subject: Re: [JAVA3D] Perf

The file sizes mean essentially nothing. Take the dimensions and multiply them then multiply for color depth (i.e. we use a lot of 256 color GIFs specifically to keep our textures small). Most likely when you load the PNG and JPG files they become 32 bit images inside Java. Most likely I'd say

The file size on disk is under 2 meg for all my textures (these are in the compressed formats of png and jpg) I did not use 32 bit color, and I assume the system keeps the textures uncompressed. How can I figure out how much vid memory is used? Is there a utility that can access the system and

Chad, If you don't think you have "too much textures" take the time to calculate out just how much memory they are all taking. You might surprise yourself. A single "full color" (32 bit color) 512x512 image takes 1 Meg. Slam just a few dozen of those around and you're seriously straining even
