Image Description, by
Inspired by many really impressive screenshots I've seen on flipcode
over the last years,
I started coding a small landscape this summer using opengl. Then, a few
days ago I thought: why not making an engine
out of it and start some game. Well, here are the first results:
I'm trying to make a speedy fun-to-play arcade-racing game mainly
focused on network playing. Maybe there'll be
computer players one day too. But currently I've other important TODOs
to get ahead, as there are:
Optimize the rendering process: First I used brute-force rendering.
Yesterday I refactored the whole rendering code
and built in some optimizations (socalled geomipmapping for example).
But I'm still fighting against cracks and gaps.
Do some dedicated server or something similar.
Terrain following of the car: Currently I've absolutely no clue how to
do it. I've some formulas and I hope
to get some working code out of them (I'll be glad to get some
suggestions and hints on this topic :-)
Collision detection with other cars/props such as plants
A basic game-physics engine
What I already have:
OpenGL based (partially) optimized terrain rendering engine with
multitexturing support
3DS model import (btw: thanks to Psionic for this cool, fully textured
low-poly car model)
A shadow precalculation program (this program takes 2 textures, blends
them together depending on the height
and adds shadows depending on the light position and returns a big
texture for the whole terrain)
Really nice stencil-buffer based shadows (you can see them very well
in the upper right picture)
A few comments on the four pictures:
Upper left: My engine in action.
Upper right: A close look to the jeep model with the shadows in action
Lower left: My track viewed from above
Lower right: You can see the optimization already working in progress
For more information, more screenshots and the progress of development
feel free to visit my
homepage.
If you've some comments or suggestions feel free to send me an
e-mail.
