Isometric with opengl

Hello all!

has anyone of you an idea how to set up an iso-view and render tiles like in eg.: Diablo?

should i setup an ortho view?

thanks for any response.

Ortho would do, but it’s not truly isometric with vertical walls. You’d have to build your own projection matrix, but it’s not really required.

If you use ortho and a few modelview rotations it will give you what you are looking for, and give you straight paralled vertical walls. You may want to add a pre projection scale in the vertical axis just to help fake out the height and counter the foreshortening effect of the viewing rotation and look a bit more like an isometric.
