texturing terrain

Someone could tell me where i can find lessons about texturing terrain which describe multitexturing (for example based on terrain’s slope) ?
Thanks for your answers.

“Ground Detail” -> “How to Apply Textures”


Splatting wastes fill rate and texture stages.
Build some transition textures, basically do your splatting off-line.
Just like the old 2d platform technique - you didn’t get them blitting a block sprite multiple times with maths ops for every pixel EVERY FRAME!

i search for an algo with at leats 2 textures depending on slope and height of the terrain. I can not use multitexturing because my card doesn’t support it. I hadn’t precised it, sorry !
