sdk still doesn't include opengl examples (yes, blame my lazyness) so try to get old one from here: http://wozniak-m.w.interia.pl/tinygl-sdk.lha it contains few simple examples using tinygl.library and glut api. if you want to use 'more native' interface you can check blanker (wavey) example in sdk. it shows how to create render target for intuituion screens using multibuffering or a target for graphics.library bitmap.
