Terrain billboarding

Recommended Posts

Hello! I already searched through the forums for billboarding, but did not find an appropiate answer for my problem: I want to place skidmarks from a racingcar on a terrain (while driving) like in racer.nl. My first idea was to make a big texture, where I place the skidmarks while driving on and then transfer the texture to the graphics card. This approach works, but it's very slow (because the texture has to be uploaded every pass and the writing of the skidmark into the big texture also takes time). Now I thought that billboarding might work better. But I have no clue on how to place skidmark textures onto the terrain. Can someone please give me hints/sources where I can find more information for this problem? thank you,

The word you are looking for is decals. You should be able to get some decent hits from google. [smile]

All the best,
