3D Level Preview




What's it for

The 3D level preview function lets you get a rough idea of what your level looks like, quickly, without all the hassle of saving, building nodes and starting DOOM. It is activated by pressing the `R' key while editing a level, and draws the player's view that you would see within DOOM (with some limitations). While the rendering window is up, you can move around the level using the cursor keys and toggle things like texturing and sprites on/off.

Key bindings

[Left]
[Right]
Turn the view left or right. Use the SHIFT key to turn a greater amount.
[Up]
[Down]
Move the view forward or back. Use the SHIFT key to move a greater distance.
[n]
[m]
Move the view sideways left or right (strafing). Uppercase `N' and `M' (i.e. with the SHIFT key) will move a greater distance.
[c]
[d]
Move the view upwards or downwards (flying). Uppercase `C' and `D' (i.e. with the SHIFT key) will move a greater distance. Note that you cannot move up or down when "walking" mode is enabled.
[t]
Toggle texture mapping. When disabled (the default), all walls, ceilings and floors are drawn with solid (somewhat random) colours.
[s]
Toggle sprites.
[w]
Toggle walking mode. When enabled, the view height is always above the current floor. For example, if you move forward over a cliff, the view will drop down. When disabled (the default), you can fly about the level at any height.
[Esc]
[q]
Exit the 3D level preview. The current viewing state (position, direction, etc) are remembered, and will be used next time the 3D preview is activated (unless the player object has been moved, or a different level was loaded).

Features

Limitations

Caveats

One last thing. The 3D preview function can use a huge amount of memory when texturing and sprites are both enabled (and a large amount even when texturing and sprites are both disabled). If your computer has a very low amount of memory (e.g. less than 16 MB), then Yadex may crash with an out of memory error. I think you are unlikely to hit this problem, but if in doubt, save your work first.
