i found some examples here
http://nio.astronomy.cz/vb/opengl.html (which seams fast for a basic aplication),
they use openGL and a wrapper called Tao, which seams to be updated recently
And it doesnt require to install a huge SDK from microsoft, these working demos are pretty small coded.
OpenGL exists in windows since i think NT3.51 so its pretty stable, and you can upgrade it like directx.
speed diffrences are not huge, so its mainly about how easy it would be to draw lines and circles.
That was easier in vb6 and earlier versions of basic like
screen 12
circle(90,90) 10, 4 but thats was before the graphic cards became smart ..
Hmm if I only could have a picturebox and have it ehmmm like assigned a such openGL power (or directx).
Then I could do all the drawings I want and fast, and then a refresh of the object to show it.
but such a could.. still is a mistery to me.
Its kind of strange we want to draw verry simple, but that seams to require a lot of knowledge these days.
