Personal projects of mine. At work, I have been mostly building enterprise (aka data entry) applications, these will not be mentioned here.
orm2d4: an XSLT2.0 stylesheet to transform NORMA ORM files to SVG. Runs in the browser via Saxon-CE
DCILtoD4: for generating Dataphor schemata from ORM schemata produced by the NORMA tool
DDILtoSQLite: the missing NORMA ORM to SQLite schema generator (seriously, missing SQLite support? are you kidding?)
2009: Flapjax-based apps
2004: Quake2 studiomdl support
What if you wanted to make a computer game based on Quake2, but you need some Half-Life features for it, such as skeletal animation and its perks: hitboxes, animation blending, "mounting" points for weapons? What we did here (jointly with Dmitry Shalkhakov, who did most of the game improvements, while I did the renderer improvements): get the source code of MDL viewer off Valve SDK, and try to integrate it into Quake2. See the result for yourself: I only put some newer models to show it off.
