Porting my game engine to the Playbook

Charilaos Kalogirou Posted on August 22, 2012August 25, 2012

The last few days I am a happy owner of a BlackBerry Playbook. The device was offered to me by RIM (thanks to Luca Filigheddu) in order to port Pop Corny to it. To tell you the truth I never owned a Blackberry device before, not to mention develop for it. It was a totally […]

No Second Carnival of Game Programming

Charilaos Kalogirou Posted on March 31, 2007

It’s been a month since the last Carnival of Game Programming and unfortunately there is not going to be a second one. The number of submitions was low and I can’t publish a carnival like that. When a critical mass of posts is collected we will have a second carnival… no fixed dates and dead […]

I think this is good news on the doorstep today! Yeap! After long thoughts I came to the decision to finally open the source code of Sylphis3D. This is going to be a big step for the development of the game engine and

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 […]

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.
