my mind is /
a big hunk of irrevocable nothing which touch and taste and smell /
and hearing and sight keep hitting and chipping with sharp fatal /
tools /
in an agony of sensual chisels i perform squirms of chrome and ex /
-ecute strides of cobalt /
nevertheless i /
feel that i cleverly am being altered that i slightly am becoming /
something a little different, in fact /
myself /
hereupon helpless i utter lilac shrieks and scarlet bellowings.

Terrain Scanner.

The Terrain Scanner will create a 3D model of a the terrain of sim, which, for instance, can be used as a map or as a basis for a sim scanner. The entire sim terrain is replicated as a textured sculpted prim.

Usage

To start the scanning process, rez the TerrainScanner object on the ground. You will see the commands as floating text above the scanner object and in local chat. If you're excited about the scanner and want to try it out quickly, just type

    scan
or
    scan region
in local chat, and it will start scanning the entire sim you're in. You can also just scan the current parcel; for that you'd type
    scan parcel
See below for detailed command descriptions.

It will take around 30 seconds (or more, depending on lag) until the scanning process is completed. After that, you will see a URL in local chat from which you can download the sculpt texture. Download the image and upload it into SL as a texture. Make sure you choose lossless compression. The TerrainScanner rezzes and textures a prim for you to which you can apply the sculpt texture (right click the prim, choose "Edit", then, in the "Object" tag drag your sculpt texture into the respective field).

If you want your name as the creator of the sim model, you can create your own sculpted prim using your generated sculpt texture. Choose "Plane" as stitching type. To texture the model with the sim map, replace the UUID in the included SetTexture script with the UUID which is chatted to you by the TerrainScanner after completing the scanning process and drop the script into your sculpted prim. The script will texture the prim and remove itself automatically.

Scanner Commands

  • Setting the size of the square to scan:
    Type
        size size_in_m
    in local chat, where size_in_m is the size of one side of the square in meters.
    E.g.,
        size 64
    will scan a 64x64 m2 piece of land once you start the scanning process. Whe you rez the scanner, the size is set to 256 (entire sim) by default.
  • Setting the starting position for scanning:
    Type
        offset offset_x, offset_y
    in local chat to set the lower left corner (the minimum x and y coordinates) of the square to scan. The coordinates are measured in meters, and are what you see in your viewer's position indicator. They are coordinates relative to the sim you're in (local sim coordinates).
    E.g.,
        offset 128,192
    will start scanning a square piece of land at the coordinates (128, 192). Make sure that the piece you're scanning is within the sim you're in. If you exceed your sim, you'll get a nonsense result. When you rez the scanner, the offset is set to (0, 0) (i.e., start at the sim corner) by default.
  • Setting the z-scaling factor:
    You can choose to make variations in land height more (or less) pronounced in your model. To do that, you can manually specify a z-scaling factor. If you leave the scaling factor to the default unchanged, the factor allowing for the most variation throughout the sim is chosen. You can set the scaling factor by typing
        scale z_scaling_factor
    in local chat.
    E.g.,
        scale 1
    will effect that each meter in height corresponds to one unit of the sculpt.
    Typing
        scale default
    will reset the z-scaling to its default behavior, i.e., such that the best scaling factor (measured over the entire sim) is used.
  • Starting the scan:
    Type
        scan
    in local chat, and the scan will be started with your current settings.
    If you type
        scan parcel
    or
        scan region
    the current parcel or the entire sim will be scanned, respectively. Using one of these commands will override any manually set scanning sizes and offsets, but not the z-scaling factor.
