Image Description, by Chronos



This screenshot is of an engine I have been working on for the past 3 months. The basis for the engine is SDL, for those looking for a fast(Unreal Tournament for Linux uses it) way to create multi-platform applications take a look at SDL(www.libsdl.org). The graphical part of the engine is written is OpenGL(hence the same ChronosGL :))

No, the background isn't some super cool terrain engine it's just a skybox. However, you are actually looking at a corner of the skybox. By displacing the texture coords by very very little I managed to create a seamless 360 degree wrap around world.

The console shown alpha blends in and has different text colors and a syntax similar to quake3. The font was created using that handy font builder which was mentioned on flipcode's main page.

The pink lines around the actual map represent the edges of an Octree. The map itself is for now just textured with a simple grass texture I got from a friend.

The 'Rain' you see is just that, rain. The lines are generated using a very simple algo which can easily be applied to many other atmospheric/particle effects. The rain for now is just lines but plan to expand it to a triangle strip so it can be textured with a more realistic effect.

It's pullin 48 - 64fps On my P3 450 w/ a Viper 770(not ultra 16mb) while running in screen res of 640x480. This is without any visibility detection.

I've also started collision detection and it seems to be going pretty well. I am planning to make a fighting game once the engine is completed...nope not full 3d...more like a Smash Brothers/Marvel Vs Capcom sorta game(no sprites though :P). If you'd like more info just email me.

Nice fonts. The skybox looks interesting. Are you going to release a demo of it?

Great screen. What do you suppose is slowing it down to 40-60 fps?
How many polys are in that screenshot? Does opening the console slow things down?

I like the console! What did you used for writing the text in it?

I like! What does your engine do?

By the way, what is causing those white specks in the picture?

I believe that's rain...

I will release a demo after I implement some sorta visibility culling. It's very very unoptimized right now. That screen shot has about 700-800 polys on it including the polys for text. Yes, the fps drops(not by much) when rain and the console are enabled. The test map file im using at the moment was generated from a quake .map file so it has 12 tris per wall which is totally killing fps. I also just started the terrain part of the engine using Compiled Vertex Arrays which is going very well. I may setup a webpage sometime in the near future for the engine, if I do the link will be on http://members.xoom.com/I_am_chronos/

If you make the "I" lowercase, it comes up.

I'm getting a forbidden error now. Is that xoom's fault, or are your CHMOD's messed up? ;)
