root engine: terrain

Description
This image shows terrain rendered by my root game-engine. You can see a landscape rendered with a high viewing range. There are 5000 flowers drawn. And a simple, static skybox. The skybox textures are created using terragen.

I'm using static lod and quadtrees for the terrain. The landscape and the textures are independent from each other, so you can specify a bump-cube-mapped texture set as well as a 1dimensional single layer texture. In this case, I have two color maps, one blend map and a shadowmap which can be generated dynamically (not realtime compatible, a 256^2 s-map costs approx. 300msecs).

I tested heightmap resolutions of 2048^2 and it worked fine. Higher reso are possible, but when using bmp-heightmaps the windows-bitmap-loader f****s up.

Theres also a plant renderer integrated in the root engine. You can setup the plant renderer for different plant densitys. For example flowers need high density, trees a medium one. :( I don't have cool tree models yet...I'm thinking of writing some code to random-generate trees based on the idea of fractals. By the way I've setup a bit vertex blending for the flowers, so it looks like every flower is animated seperately).

Facts:
- 5000Flowers = 20.000polies (put in one vertex buffer for drawing)
- 48 FPS when not moving ( = no plant re-sorting ), 25-30 when moving
- my system: Athlon XP 1800+, Raden 9700 pro (128MB), 512 MB DDR

Unbelievable... I must say it looks very nice on those screenies!!!! I definetely want to see a demo with that engine! Keep up the good work!

Very nice IOTD! :-)

Very nice image, and quite a good framerate aswell. The flowers are the perfect balance between pretty and poly. Good work.

Very good picture and very good Framerate with such number of flowers.

Well done!
