Hardware Accelerated 3D using 2D Compositing



Wellington, 8th February 2012

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.
