3D library for X
A new 3D graphics library was released yesterday. It aims for GL compatibility in the future. I've compiled it and the demos at ~trowley/work/tmp/tagl. - Tim Rowley trowley at geom.umn.edu ---------------------------CUT HERE-------------------------------- TAGL 1.0 ======== TAGL is a portable library wich offers similar functionalities as SGI-GL. It will become compatible with GL in the future. Requirement: ============ o A Unix system with X11R5 and MIT XSHM extension. (tested under Linux and SunOS) o Can be easily ported to whatever system wich has linear memory and a 8bpp (I think it takes 1/4h to port it, that what it took for svgalib under Linux). Features: ========= o Double buffering o Polygon clipping o Polygon drawing, filling and shading (Gouraud) o Dithering o Z-Buffer o Built-in font (it will use X11 fonts in the future) o Basic io (Keyboard and mouse) o Schumaker convex grape rendering o Simple lighting model o Depth cueing o Zooming o Simple 3D transform o Fast integer fixed point math o Built in sine and cosine tables Sample programs: ================ o testgl: basic test of the library, rotate 3d objects as convex grapes, test ZBuffer. o mars: something that will become similar to the mars demo (to mars's author: excuse me to have given the same name as your demo to such a thing, but it's only a small test of the library, it will become something that looks like your demo later on ...) o rotate: rotate objects in off format and Aegis 3DG1 format. test rendering methods, ZBuffer, mouse input and built-in font. sample off files come from avalon.chinalake.navy.mil (18.104.22.168) and 3DG1 files have been modelled by a friend of mine, Jean Balcaen. (Thanx a lot, Jean !!) 3DG1 have not always their normal vectors set properly, so lighting may look strange on these files. ( about which key does what, h toggles help screen, some functions are not in the help screen, so look at the source code - I don't have enough time to write sample programs man pages - It will come later on with tagl 2.0 distrib ) Distribution: ============= sunsite.unc.edu Author: ======= Bruno Levy e-mail : levyb at loria.fr (it will change after the hollyday) snail-mail: 6 bis rue du General Frere - 54500 Vandoeuvre - France Performance: ============ More than 1000 faces/s with Gouraud and ZBuffer in 640x480 on a 486 dx 33 running Linux. (almost the same on a sun10) ( to have 640x480, make clean; make hires ) X-SHM: ====== X-SHM support has been mainly inspired by mpeg_play Bugs: ===== Standard X support (without SHM) does not work for the moment. (It can't run on a TX, it must be on a workstation). Future developpement: ===================== o All this stuff will become C++ classes (very soon, work in process). o A complete fixed point math library will be embedded. o GL compatibility is for soon. o The texture mapping function is ready, but not embedded yet in the library. (It was, but I had a head crash on my HDD, I was lucky not to loose the entire library !!!). Starting up with TAGL: ====================== gunzip tagl-1.0.tar.gz tar xf tagl-1.0.tar cd tagl make (for 320x200), or make hires (for 640x480) rotate.exe -geo geo/one_of_the_geom_files rotate.exe -3DG1 3dg1/one_of_the_3dg1_files '!' key toggles opaque move 'w' key change render mode middle mouse button + move : rotate objects left mouse button : zoom in right mouse button : zoom out both three buttons : rotate Z axis 7-4-1, 8-5-2, 9-6-3 : auto-rotate
