News / Version 0.83 beta 2 has been released!
« on: January 26, 2003, 12:43:20 am »
I updated beta2 with a new jpct.jar that fixes an accuracy flaw in the SoftGLRenderer...but no new version number for that one.

Support / Wireframe or border rendering?
« on: January 25, 2003, 05:51:48 pm »
Hmmm...i have to think about this when i have a little more time, but i think that i understand what you are trying to achieve. Just one question: Would it help to draw the border into a texture, i.e. does the texture cover the polygon and ONLY the polygon that should show the outlines? I guess it doesn't, but i had to ask...that would make things easier.

Ok, i've added it to the latest release. Hope it helps.

I've added a 3DS loader, some more options to the Primitives-class and made some minor fixes and improvements.

Support / JAW-file format specifications
« on: January 21, 2003, 11:34:45 pm »
Finally, i decided to add support for the 3DS format to the next beta. I already have an alpha version of the loader running and it's working quite well so far.

Support / JAW-file format specifications
« on: January 21, 2003, 06:33:54 pm »
Good question...one should think that it's easy to find some specifications at least for ASC, because it is a quite popular format (It's an ASCII export format of older versions of 3DStudio). But i have to admit, that i couldn't find any...the thing is that ASC is easy to understand by looking at an ASC-file in a text editor. jPCT's ASC loader doesn't use all the information an ASC-file offers. What's used is the vertex list (x,y,z and u and v if given) and the face list. A single file may contain a number of vertex and face lists. That's all...should be quite simple to understand by studying such a file.
I included an example file in an archive here: http://www.jpct.net/download/asc_and_jaw.zip
JAW is an outdated format of a discontinued engine that i'm using for historical reasons. It's basically a stripped down version of ASC which contains only one large vertex- and face list. It's still supported, because i own some simple JAW-objects myself that i would like to use and it may be handy as a quick-and-dirty format that your own applications may write.
I know that this is not very satisfying...some more advanced loaders for other formats would be nice, but i'm currently doing other things with the engine. (To be honest, i'm still waiting for someone to write them for me, because i don't have fun writing loaders... :lol: ...just kidding...but it would be nice though).

0.83 beta 1 is out and hopefully fixes this flaw as well as some others.

News / Version 0.83 beta 1 has been released!
« on: January 20, 2003, 11:50:34 pm »
This version is the first version of jPCT that offers hardware acceleration as an option (via OpenGL and using LWJGL). Adding OpenGL support required to do a lot of changes in some parts of the programming, so i decided to release this version as beta 1 and not as a regular release. The documentation reflects the changes but some parts will most likely need further work...anyway, here is 0.83 beta 1!!
I replaced the terrain example applet with a terrain application that makes use of the new OpenGL support (can be run in software as well).
The OpenGL support should be transparent to code written for older versions of jPCT, i.e. if you're not interested in OpenGL support but in the other features and fixes this version offers, just replace your old version of jPCT with the new one...it should work as usual without changes. If it doesn't, please let me know... :wink:
set- and getCamera() in the Camera.class are deprecated now. They have been replaced by set- and getPosition().
Edit: A slightly updated version has been uploaded that fixes a problem with drivers that return a refresh-rate of 0 Hz.

Quick question for Helge... I can't find a way to cast shadows.No, there isn't. You'll have to do it the "texture-way". I thought about shadows some weeks ago, but i ran into some problems (virtual ones...i didn't really implement something) with the software rasterizer. That, and they would be veeery slow in software. Maybe the upcoming support for OpenGL will make me re-evaluate this decision...but for now: No support for casting shadows, sorry.
It's not a big problem (because I can always burn them onto my textures :wink: ), but... is there a way to do it using the engine?

The same example using the new OpenGL support (not yet released!):

News / jPCT is going OpenGL...
« on: January 14, 2003, 12:25:20 am »
Update: The OpenGL version is showing nice progress, Here is a screenshot of the terrain example converted to OpenGL (i.e. converted to an application...there's really not much more required to make it use OGL).
Some features of the software renderer like 2D blitting won't be supported by the first version of the OpenGL renderer. Anyway, the release date of the new version is...when it's done!
Edit: At least 2D blitting from textures WILL be supported...

jPCT tries to hide the 3D specific stuff from the user as much as possible while maintaining an easy to use API. I hope that it not only tries this but achieves it to a degree. If it doesn't...feel free to ask...

News / jPCT is going OpenGL...
« on: January 09, 2003, 01:17:33 am »
...i finally started to implement support for hardware accelerated rendering in jPCT (via OpenGL using LWJGL). It looks promising so far but there's still a long way to go until both renderers (software and OpenGL) will behave as similar as possible (that's quite difficult to achieve, because the software renderer is capable of some things OpenGL simply can't do...overbright lighting is one of them for example).
Anyway, here are two shots of the demo. The first one is rendered using the good old software renderer and the second one uses OpenGL (still very unoptimized).
Edit: I removed the poll from this thread. jPCT supports OpenGL nowm so the poll was rather outdated.
Edit: jPCT will remain Java1.1 compatible (the OpenGL renderer won't...) as it loads the renderers on demand, so don't worry...
