Eye of the Beholder Maze Format

This page describes the maze format in Eye of the Beholder, which are saved in .MAZ files.

The 2D-View is calculated by a map of the "view-cone" for each view direction. The tile-sides which point towards the players direction plus the left/right sides depending on the side of the cones center are used.

! Add grid display of "View-Cone"

! Give general description of the way the format works

! Add Template:Map Infobox. Will need a new type for "2D maze viewed in first person 3D"

Generally all new calculated positions are clamped using binary AND. Example: [New Position] & 0x3FF. This creates a wraparound effect which is used in EOB1 for the Spider-Level for a long hallway which extends the maximum 32 Tiles in the Y-Direction.

The same format is used in Lands of Lore but compressed with LCW compression, and using the file extension .CMZ.
