I'm learning building AR with ARToolkit library. I conducted some observation from the sourcecode provided by this library, let's say simpletest. and then in draw function I changed the translation value of z axis from 25.0 to 0.0 (original: glTranslatef(0.0, 0.0, 25.0) to glTranslatef(0.0, 0.0, 0.0)). when I did this, I found out that the cube I rendered as if "running" as I rotated my marker along x axis. Meanwhile using the original, it does not "running" when I rotated the marker. Can anyone explain why it was that?
glTranslatef(0.0, 0.0, 0.0)) yieldshttp://i48.tinypic.com/2803f4.jpg
original: glTranslatef(0.0, 0.0, 25.0) yieldshttp://i50.tinypic.com/2hi8j1e.jpg
