HDR Procedural Skies

Charilaos Kalogirou Posted on November 23, 2006November 23, 2006

The under development branch of Sylphis3D is going to support high quality terrain rendering. At the moment the terrain rendering code is in place and produces some very nice views! However the sky support was limited to skybox rendering. At first I thought I would just go for some HDR textured skybox. This was good […]

How to do good bloom for HDR rendering

Charilaos Kalogirou Posted on May 20, 2006December 2, 2006

One thing that makes HDR rendering impressive is the bloom effect. In fact even if bloom is in a sense decoupled from HDR rendering, it is often confused with HDR. There are 3d engines out there that advertise bloom for HDR rendering, which is nonsense. You can have HDR rendering without bloom, and you can […]

HDRR screenshots

Charilaos Kalogirou Posted on May 15, 2006May 15, 2006

Here are some screenshots of the HDRR implementation in Sylphis3D. Sylphis3D is now capable of HDRR on video cards starting from ATI Radeon 9600 and nVidia FX5200 and up. (Yeap… no need for those expensive nVidia 6800 cards)…

Programmable GPUs and the programming method

Charilaos Kalogirou Posted on May 12, 2006May 12, 2006

Working heavily on pixel shaders the last few days, I came to realize some facts about the current way of treating the GPUs and how that way is inefficient/impractical and really doesn’t allow us to fully harness the powers of GPUs.

Sylphis3D now uses Stackless Python 2.4

Charilaos Kalogirou Posted on March 21, 2006

Yesterday I upgraded the Stackless Python used in Sylphis3D. Until now I was using version 2.2. This was a bit outdated since the latest Stackless Python was 2.3. I was quite happy with 2.2 and had no problems at all, so I wasn’t considering to upgrade. But now that 2.4

Considering a licensing option for Sylphis3D

Charilaos Kalogirou Posted on March 15, 2006March 15, 2006

If you follow this blog for more that this post, you probably know the 3D game engine Sylphis3D. The engine itself is ranked at the high end engines of the times providing DOOM 3 equivalent capabilities. It was actually providing these capabilities for quite some time before DOOM 3 shipped. Anyway since until now I […]

Stackless Python presentation

Charilaos Kalogirou Posted on March 11, 2006March 11, 2006

Kristján Jónsson from CCP Games did a presentation about their use of Stackless python in their MMORPG game. The use of Stackless in EVE Online is very close to the use of Stackless in Sylphis so I recomment it as a good reading along with my post about stackless. The presentation can be downloaded

Creating a benchmark script for Sylphis3D

Charilaos Kalogirou Posted on February 3, 2006February 5, 2006

Suppose that you want to benchmark a 3D game engine. What do you do? The common solution is: Have a demo file to play Play it on the benchmark machine Count the time elapsed Next is a script to do this in Sylphis3D:
