| Nice work Hans!
Now who will take this open source code of Hans and use it to make a new game for OS4.x?

| Awesome work Hans, it's really looking good! Can't wait to see MiniGL run on these eventually. |

| Out of curiosity what is the name of the folder where the file Composite3DDemo is located?
Thanks

| Managed to look at the code, just out of intrest.Yaay.. He got Quaternion power to the Quaternion. I couldnt for teh life of me work out how to do that until late last year, when the generalised Euler formula popped up on Wiki. 8)
Thing is, looking through it, he says things can only be Euclidean, that is no stretch or quash. But 4D matrices contain not only 3D rotations and translation, but shears and stretches, I beleive dependant on the 4th row, column non identity element.Im afraid its a lot of years since I was writing all the various functions down in order to colelct tehm together, but they come in very useful.
A simple example will be in the Boingball demo, you take the normal of the ball along its propagation axis, then for some function of nearness to impact point, you deform the impact axis, elongating, as in cartoon stretch, redusing the other cross sectional axis preferably in ratio to keep a function of constant volume or cross sectional area etc, then on impact you inverse the ratio of elongation, so the ball squashes, but in doing so, you rotate the normal of the ball through twice the angle to the normal of the impact plane, then reversing teh ratio so teh ball elongates then recovers on teh bounce.
Further improvements would be the application of the forced damped oscilation polynomial, extended to higher harmonics, preferably with precalculated error limits as are used already in teh demo, to tell when complex calculations would be of no further use.
Will be intresting to see just how many dynamically elastic boingballs can be shaken in a tub in AOS when fully running. 8)
Trouble is, to make a pool or pinball game, still need moment of inertia, surface friction and other functions.
Things will eventually arrive. 8)

| Great! This was just what I needed to finish my 3D-demo. Maybe I can mark one of my projects as done. :) |

| Hello,
Congratulations for this demo, very well done.
It seems that a bug occurs on my SamFlex Unit (777 Mhz), Radeon 9250 128 Mo
There is a white part on the upper/left corner of the screenshot that looks strange.
Please have a look here
Hope it helps.
