Hi all, What is the Z-coordinate for in terrain. For example, if I am rendering a terrain made up of quads, I set the Y-vertices from the value I get from my height map, but what about the Z? Also, after drawing the first quad, I''m presuming the next quad has to start from the last quads x,y position as shown below: |\ |\ | | \| \| 1 2 Thus quad 2''s x,y vertices same as quad 1''s ? If not surely the quads wouldn''t be joined together ? Kind regards, Steve

If y is height, and you know what you do with x, isn't it quite obvious what you have z for?

EDIT: this is the map viewed from above...

Thanks,

So, Z is the columns of the map - right ?

What I meant to say is how do you generate the Z vertices when making the vertices for the quads of the terrain.

Thanks,
Steve

Naturally, for a pixel of location (row,col) you use row to calculate the X position, and the col to calculate the Z position.

Cheers,
