FWIW this is exactly what the car racing sim iRacing does, they laser 
scan in the tracks and use this data for the physics. They then build up 
a traditional triangle-based mesh and textures for the graphics. Of 
course there is the risk the two are disjointed, and it sometimes 
happens that you get release notes like "fixed issue where a car appears 
to hover above the track at XXX".
