Heightmap collision

[bizzard4]

Hi I am currently trying to do a heightmap collision with Newton and DirectX and I have some question :

1) What theoricaly you are doing in the MeshCollisionCollideCallback callback in tutorial 08. Because I cant figure out what you are trying to do... but it work so to translate it to DirectX I need to know what you are doing

2) I see some place in the forum this method : NewtonCreateHeightFieldCollision but it not exist in the 1.52 SDK ?

3) Is the SDK 2.0 is released ?

Thx to all I am new here
