Matrix Multiply

I’ve been doing a lot of 3D programming in my spare time. Though parts of it were spent doing mostly in research and study.  Take for example the time I spent going through bits and pieces of information figuring out the details of Matrix Transformations, you probably know and can probably count the number of nights spent on it.

Anyway, with the help of a friend who badly needed a Matrix Transform lib written entirely in C, he’s trying not to borrow code from the Web so as not to get a lower grade, we finally sat down and wrote probably the shortest quick-n-dirty version of the Matrix Transform ever coded.

With most of the basic Transform functions squared-away, I finally got it added on top the OpenGL engine wrapper.  The first test was basically loading a 3DS mesh file into the world before rotating, scaling and translating it to a location. That test went very well, the Matrix Transform worked right away with no hiccups. I thought the model will come out mangled in knots, but somehow, the model got rotated, scaled and translated as planned.

The next test will start soon, though the elements needed to get the test going aren’t there yet. The B3D loader is still 50% complete and the slerp() function is yet to to coded. For some unknown reason, I somehow got hooked into B3D format mainly because of its completeness and simplicity.

 The B3D loader is LGLP’d and is available on SF.net.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.
