Getting Started Again… True Megatexture

Comments   2   Date Arrow  August 28, 2007 at 1:45pm   User  by Harry Kalogirou

Greetings everybody!

It been a long time since this blog was updated, I know! Well I was kind of busy lately. Looking for a job, finding a job, then doing the job and finally trying to get some free time for summer vacation and free time projects. You know that getting a new job always makes […]

The wait is over… Sylphis3D is open source!

Comments   11   Date Arrow  April 11, 2007 at 5:29pm   User  by Harry Kalogirou

I just release the source to Sylphis3D! Check out the story at the Developer Network.

The wait is over! Sylphis3D is officially released under the GNU GPL ver.2 (with the classpath exception for those that need closed source solutions). The engine weights at around 45000 lines of source code written in C++ and Python.

The source code […]

No Second Carnival of Game Programming

Comments   0   Date Arrow  March 31, 2007 at 9:51pm   User  by Harry Kalogirou

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 lines… […]

Sylphis3D goes open source : BSD or GPL ?

Comments   25   Date Arrow  March 28, 2007 at 12:05am   User  by Harry Kalogirou

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 I would really like to welcome you to it.

If you followed […]

HDR Procedural Skies

Comments   2   Date Arrow  November 23, 2006 at 12:20am   User  by Harry Kalogirou

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

Comments   16   Date Arrow  May 20, 2006 at 9:32pm   User  by Harry Kalogirou

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

Comments   0   Date Arrow  May 15, 2006 at 5:06pm   User  by Harry Kalogirou

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

Comments   4   Date Arrow  May 12, 2006 at 10:22am   User  by Harry Kalogirou

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.

The progress of GPUs

When some years ago the first graphics accelerators came to light, the […]

HDR lighting… possibilities…

Comments   0   Date Arrow  May 11, 2006 at 9:29am   User  by Harry Kalogirou

The sillent blog the last few days is due to the heavy work going on in Sylphis3D… I have almost completed work on the HDR implementation in the engine. It took some brains to put it in there, especialy since it had to work with Radeon 9600 and FX 5200 …

Stay tuned for […]

OpenGL render to texture problems

Comments   1   Date Arrow  April 18, 2006 at 1:04am   User  by Harry Kalogirou

The time 1:52 in the morning and I just had those “OpenGL” moments again! It seems that the nightmare will never end. An other problem with RTT came up. As you know Sylphis3D uses the stencil shadow method, and therefore needs a stencil buffer. Now that I am implementing high dynamic range (HDR) rendering, I […]
