   Getting height of terrain

Hi Reimer and everyone else,

Is there a way of retrieving the height of the terrain at an object location.

So I can load objects at terrain level just based on the x, y co-ordinates.

This would also come in handy for creating my character walk at terrain level at all times no matter the shape of terrain.

Thanks in advance

Just a thought by why not just look at your heightmap?

would that not be the simplest option.

Assuming your heightmap data is in a float[,] ...

float heightAtPointX = heightMap[x,y];

?!?!?!?!?!?!?!?

Or did i miss something?

Your heightmap gives coordinates only for specific integer points, but the terrain itself is generated smooth, by some directx graphic functions. If You have 2 points: (1,1,1) and (2,2,2) and character is standing (1.5,y,1.5), y of terrain will not be exactly 1.5, because of points are not connected straight line, it is round curve, so you may have y=1.4 or y=1.7, depending on what height has neighbour points
