I have an interesting problem. My computer at work loads and applies textures correctly, but my computer at home does not. All I get there are white objects no matter the type of file loaded (jpg, png, dds, etc.) Both computers have the same NetBeans project, the same java (1.6) and jogl (1.1.1 rc2) versions, and the same texture files. Any ideas on what might be the issue? If more info is needed about the situation, just let me know. Thanks.
for sure the computer’s loading as fast as it can. but any of those computers should load properly the textures, whatever be the configuration.
In fact, one programmer must pay much attention to the loading processes as they have to be monitored by one or more instances, i.e. the MediTracker is one of those monitors. Moreover it has to be checked for the heap space available on each configuration, which can vary from 0 to Gigabytes. Thus the harddisk-space should be used to cache the datas, such as textures or binaries. once checked these 2-3 rules, it can be assumed that the memory is managed, such a statement is a.k.a Virtual Memory Space, isn’t it?
Java has more and more enhancements about VMS stored in the Java Management Beans i[/i]and usual Referencesi [/i]packages. You may be interested in that. :
It might be related to how you’re producing texture coordinates for your objects. If you’re using JOGL’s built-in TextureIO classes they may be switching to using GL_ARB_texture_rectangle behind the scenes. See the javadoc for Texture.getImageTexCoords() and Texture.getSubImageTexCoords().
Do they have the same graphics cards or drivers? I installed Ghost Recon on an old machine and everything came out as white (ie no textures). I installed a much newer graphics card and the textures worked fine. This could be your issue.
Yeah. I tried this last night by moving the project to my other computer at the house, and things worked fine. I checked the date on the video drivers for the first home computer and found they were rather old. Unfortunately when I tried to update them, the ATI site said I had to get them from the computer manufacturer. (The computer is a Sony VAIO.) Even the driver from Sony is a good 2 years old. I think am may just develop on my home desktop for now since I am in the process of building a new computer.
So long story short, it is most likely the video drivers being out of date if not just the video card itself being too old. Sigh.
