Is it possible to make 3D isomatric land? Not that it just looks like 3D, such as in Transport Tycoon alike games, but so that it is possible to see the diffrents in hights when the camara is moving?

Try some researtch on orthographic projection. Isometric merely implies that you are looking ad the tiles from a certain, fixed angle (so that all edges are the same length) and are performing orthographic projection.

If you want to use other (often better-looking) false perspectives, simply use orthographic projection with the appropriate angles.

In our project, we do this, and it looks much like 3D, but still is 'isometric' (actually orthographic) - units and features in the distance won't get smaller, but you will still see a parallax when rotating the map.

Interesting Web Link on orthographic projection methods, covering iso-, di-, and trimetric perspective. There is more on perspectives in the document, just browse back and forth a bit.

IIRC Red Alert 2 is a 2D Isometric game that uses voxel sprites for the units.

Exactly what do you mean 3D isometric land, do you mean exactly like Transport Tycoon (2D Iso engine with height) or 3D isometric (using a proper 3D engine but forced to show in Isometric way)

If it''s the first one, check the articles section of this site for my Iso Mouse maps with height article, in which I explain how to add height to TANSTAAFL''s mouse maps code.

If it''s 3D engine then again look in the articles section as there is an article on dooing iso projections in D3D..

When I find my code in tons of trouble,
Friends and colleages come to me,

I mean a whole 3D world wich looks like the 2D isomatric view. So when you are possible to change the angle of the camara to a "normal" human view, but you still see the tiles.

Well, perhaps I should leave it for a while and just use a normal 2D isomatric view with 3D graphics.

You CANNOT switch into a first person perspective in Isometric Graphics - stuff that is distant will look exactly the same size as stuff that is close by. It''d totally suck.

Warcraft 3 and Armies of Exigo both use tile-based 3D graphics, though.

Did ''Populus: The Beginning'' suck? I admit it didnt have a first person view but you could change the view angle to one that was almost parallel to the ground. And yes, stuff in the distance was the same size as stuff up close.
