camera - camera handle mode - 0: no fog (default) 1: linear fog |
|
Sets the camera fog mode. This will enable/disable fogging, a technique used to gradually fade out graphics the further they are away from the camera. This can be used to avoid 'pop-up', the moment at which 3D objects suddenly appear on the horizon. The default fog colour is black and the default fog range is 1-1000, although these can be changed by using dxCameraFogColor and dxCameraFogRange respectively. Each camera can have its own fog mode, for multiple on-screen fog effects. |
