vegetation

[dixx]

• How can terrain be marked for certain vegetation types?
• How can vegetation be set to the world?
• Collideable or not?

A cool thing to use together with a seeded randomizer would be: http://devmag.org.za/2009/05/03/poisson-disk-sampling and maybe http://devmag.org.za/2009/04/25/perlin-noise/

Vegetation should be not collideable in general. Special veggies should have an additional collision model, and will be set manually.

Vegetation, also with animation could be created like this: http://http.developer.nvidia.com/GPUGems/gpugems_ch07.html

That is a great approach to generate all the Vegetation stuff. But isn't such a functionality also part of irrlicht? (If not why?)

It is not part of Irrlicht because there are a dozend approaches how to generate grass and veggies. And Irrlicht is a 3d engine, not an RPG maker :) There is no right or wrong. In our case, we should use the approach pointed out by NVidia, but customize the model and the movement algorithm, to save FPS. We do not need ultra-HD grass, as we do not create a shooter.
