Software News   Software News : Hardware Accelerated 3D using 2D Compositing

Hardware Accelerated 3D using 2D Compositing

AmigaOS graphics guru, Hans de Ruiter, has issued another update to his RadeonHD graphics driver for the AmigaOS. Version 0.32, which makes its official debut on the AmigaOS 4.1 Update 5 CD especially created for AmigaONE X1000 "First Contact" system, delivers full 2D support for all Radeon graphics cards from the Radeon X1300 through to the RadeonHD 4890.


When asked about the improvements in his new driver De Ruiter said, "I'm quite pleased with the updated driver. Apart from fixing a few bugs, the biggest change is the addition of homogeneous texture coordinate support to the compositing function. This allows 2D warping and even perspective-correct texturing". In reply, A-EON Technology's Trevor Dickinson commented, "I am pleased to help support Hans' graphics driver work and look forward to the future release of hardware accelerated 3D graphics drivers which should benefit the AmigaONE X1000 all other AmigaOS 4 users".

To illustrate the improvements in his new driver De Ruiter created "Composite3DDemo", an interactive 3D "Boing Ball" demo remake that renders everything using hardware accelerated 2D graphics without the use of 3D drivers. Originally developed as a test application for the RadeonHD driver running on the AmigaONE X1000, it demonstrates what can be done with AmigaOS 4.1's powerful compositing feature and a little creative thinking. In other good news De Ruiter revealed that he is releasing the source-code which he hope will help others to use these features, and encourage them to see what they can do. The "Composite3DDemo" is included on the AmigaOS 4.1 Update 5 CD and can be downloaded from the web link shown below. Please also check the link to the "YouTube" video.

About Hans de Ruiter & HDRLab: Hans de Ruiter is an electrical & electronic engineer and leading AmigaOS developer and Amiga enthusiast. His website - HDRLab - details various projects, many of which are AmigaOS related. The biggest of these is the RadeonHD driver for AmigaOS, an ambitious project that aims to deliver modern graphics capabilities for the AmigaOS platform.

Nice work Hans!

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

Hans is a serious asset on OS4 development efforts... lets get the real 3d drivers out too Hans!

I'd agree with you, but then we'd both be wrong.

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

Good work! Even works on my "small" SAM440ep System.

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.
