A new version is at http://jijigaga.com/qrli with much more function. It's only tested on D6, D7, K1 and K2. For the others, some modification is needed. I'm not working on it for a time and I don't have the condition. Maybe someone can take it over...
This sample shows the usage without IDE's form designer. You can also use TGLWidget as a commom control if you compile the GLWidget.pas into a package.
HighQualityScene procedure added,
dual SwapBuffer bug fixed,
texture utilities added,
bitmap font class added.
