F.L.A.S.W.F: terrain

Ken Silverman's GROUFST2 Terrain Raycaster - wonderfl build flash online

Simple nice heightmap terrain raycaster, a good start for your own voxel engine.

Happy Coding 2011!

back later...
I do like playing with terrains.
Generally there are two ways of rendering terrains or landscapes, the first one is called voxel, the second one is using 3D triangles.
There are difference between the two ways, both in theory and the result.
Many flashers did some very impressive experiments about terrains by action script.
1.A great one was Electric Oyster 's flash flight simulator over the arctic.
The swf is based on their own 3D engine-Electric 3D engine using tiangles way to render the terrain.
Great texture and rendering speed!

a full screen version :

P.S.Anyone who want an standalone (off-line) vision,just go to your Temporary Internet Files’ folder,copy the files ‘Main.swf’and‘data_lq.bin’ out, save them where you want.(don’t change the name of the second one,keep it ‘data_lq.bin’)-play ‘Main.swf’
for full screen version it will be 'data_hq.bin'
you may need to take care of flash player's security problems.
2. away 3D greenpalnt demo

much more than just landscape, very impressive!
3. Den Ivanov did lots of beautiful experiment on terrain.
The most famous one is his land craft simulator in flash 8.

He also did other simple voxel terrain with source their

But PaperTerrain :http://www.cleoag.ru/2007/03/31/sources-for-papervision3d-terrain/is using another approach papervision 3D
And triangles.(with source)

an old work realtime 3D landscape:

(sorry, can't find the original link...)

We can easily see the difference of final result:
Voxel is much more month, on the other hand you can recognize the triangles
