gluLookAt and a tile-based top down view

OpenGL OpenGL: Basic Coding

Hi everyone,

Just a hopefully simple question about gluLookAt. Since the UP vector cannot be parallel to the view direction vector, to achieve a top down tile-based camera, would we have to create our own model view matrix to handle this?

Would anyone be able to point me in the right direction to achieve this?

Regards.

Just change your up direction to be parallel with the plane of the tiles. If your tiles are in the XY plane, just have your up axis be +Y. Your view direction will be along the Z axis.

Thanks Alfonse, very simple indeed!
