Kia-Ora! Welcome to HDRLab. My name is Hans de Ruiter, and this website is devoted to various software development/engineering projects of mine (mostly Amiga OS 4 related) and anything else that I find interesting (e.g., electronics, mechatronics, or anything engineering related).  If you're into technology, building things, or are just curious, browse through this site using the menu above, or have a look at the recent updates below. Feel free to contact me if you have any suggestions.

Backup and Restore of Trac and Subversion

Whilst the SubVersioN (SVN) repository acts as a backup in many ways, it is still worth making a backup. The repository holds more than just a backup of the developer files, it holds a record of every change that anyone has ever made to the source files.The Trac project pages can also hold important information. Given that keeping this data is critical to a software project's existence (and possibly the livelihood of the company/induviduals that own it), it is worth protecting.

RadeonHD Card Recommendations for AmigaOS 4.x

Many people have been asking me for advice as to which Radeon HD graphics card they should buy for their Amiga. So, here are my recommendations. For the lazy, there is a quick summary at the end of the page. But first, a quick disclaimer:



About Me

Hans de Ruiter

I am an electrical & electronic engineer from New Zealand, with a Ph.D. in applied science/engineering from the University of Toronto, Ontario, Canada. As can be expected, many of my interests are computer and engineering related. However, I also enjoy hiking and the outdoors. Playing violin and piano are also spare time hobbies of mine. 



GfxBench2D's Traffic Spike

I haven't posted to this blog in a long while, so I thought that I would share some interesting traffic data related to the newest section of the website. Just over a month ago I released GfxBench2D, a 2D benchmarking tool and web-application. This tool measures 2D graphics performance and can (optionally) upload results to this website for display. Well, this triggered the biggest traffic spike that this website has ever seen. Take a look a graph of the number of daily visits that have occurred since this website was first created (up to 10 July 2011):



Amiga What?

 



RadeonHD Driver

The goal of this project is to write Amiga OS 4.x graphics drivers for R5xx and higher graphics cards, both 2D and 3D. One of the motivations for this is that, my computer vision research extensively uses shaders that are present in modern GPUs. None of the existing supported graphics cards for Amiga OS 4.x support shaders.  Shaders are rapidly becoming an essential component for running newer games. Rather than write 3D drivers from scratch, Gallium3D - the new driver system for MESA - will be used.



RadeonHD - First Screen

An image shown by a Radeon X1300 graphics card in an Amiga-oneToday marks the first milestone in the RadeonHD for Amiga OS 4 project. A Radeon X1300 graphics card has successfully been programmed to open a 1280x1024 true-colour screen and an image has been displayed. The graphics card was a VisionTek Radeon X1300 256MB PCI card that has been plugged into one of the PCI slots in my Amiga-one for over half a year now. With this success, I am now confident that I can, in time, write a proper Amiga OS 4.x driver for this card. Thus, this project is now revealed on this website for the first time.



Month in Review - December 2008

This month has seen significant additions to this website, as can be seen with an increase from 112 to 132 pages. I have had much more time to spend on this site than usual, due in part to not having my Amiga one and, thus, being unable to work on the RadeonHD for Amiga OS 4 project. There as also been more free time in general.



GfxBench2D the First Release

Welcome to yet another development log. This post marks the first release of the GfxBench2D benchmark tool, and the corresponding web application (web-app). The benchmark tool tests the performance of graphics cards for a range of different operations, and (optionally) uploads the results to this website for display. While it is still a work-in-progress (isn't most software?), it has reached a point at which it is useful.
