wow Caballero,I wonder how did you do it,so it behaved cool strangely on my xp computer?I clicked on 'x' on window and window+black background disappeared and a rotating 3dsphere was still on my desktop,but everything around it was transparent,I was able to switch to other windows also and when I wanted to close it I clicked on the sphere and esc
very nice flag Siekmanski
SIMD matrix blocks?,sounds very interesting
now when being busy with working with graphics,I see a need of support group hierarchy when you need to use complex 3d objects in a game or demo
does that need some recursion algo to go from highest group 3dtransforms to go down to tiny details,to lots of very tiny parts of objects when it explodes
