====== PEW File Format ======

====== Introduction ======

PEW are Visitor's project files. Visitor is BIS tool for creating terrains.

Visitor is a GUI tool that interacts with Bulldozer, an inbuilt 'world' viewer inside any Armed Assault engine.

The contents of the project file, pew, are not directly related to the ultimate output, a wrp file. However, that data, of course, contains all similar elements, such as road networks, elevations, cell matrices, models and textures.

Exporting a pew file into wrp format, involves the use of Bulldozer, since it is Bulldozer that decides how it wants that data presented, rather than anything visitor might like to decide. It is Bulldozer that determines the format and version of the resulting wrp file (in 8WVR format), and consequently, that, is a reflection of the Arma Engine itself.

While there have been several pew versions, the one's listed here are
<code>
*POSEW59 and
*POSEW60
</code>

there are only a few subtle differences to their makeup.

====== File Format ======

This file format is principally used with Armed Assault v1.09 and later plus the ArmA Tools Suite Final release (v1.14).

    RoadList     Specials[[nSpecials]];
    ulong        nTerminators;
    RoadList     Terminators[[nTerminators]];
    }
  }
</code>


====== RoadList ======

<code cpp>
  RoadList     
  {
       String      ModelName;      // &quot;cesta25&quot;
       ulong       ObjectID;       // in the model list
       ushort      MeterType;      // 0,1,2,3 not present for Terminators
       shortBool   CanChangeAngle; // not present for Terminators or Curves
  }

MeterType
:Type Straights Curves
:0      6         25   meters
:1     12         50
:2     25         75
:3               100
</code>

Broadly speaking, there are a few basic road types

<code>
*asfalt   bitumen.
*silnice  Paved
*cesta    dirt
</code>

Each RoadType describes the general characteristics of a Dirt Road as opposed to (say) an Asphalt one.

Each of these RoadTypes  (such as asphalt) can have multiple curved, straight, special, and termination p3d models associated with them.

Generally speaking, there are 
<code>
*3 'straight' models, approximately 6,12, and 25 meters long respectively.
*4 'curved' models, 25,50,75 and 100 meters long.
*1 'terminaton type.
</code>
The termination type is a road like any other but tends to be a fixed 6 meter fade out of the general road texture.


====== XRoad ======

<code cpp>
 XRoad
 {
  String    Name;	      //kr_asfaltka_asfaltka_t.
  ushort    Shape;            //1 or 3
  RGBA      color;	      //FF FF FF FF 
  shortBool CanChangeBankAngle;
  ulong     ObjectID;
  String    Intersections[[4]]; //&quot;asfaltka&quot;,&quot;silnice&quot;,&quot;cesta&quot;,Type=3 &quot;silnice&quot; else &quot;&quot;
 }
</code>

Although CrossRoads could, conceivably, have any number of intersections, only two types are handled.

<code>
*Type 1: A T_Junction (3 intersections)
*Type 3: A Genuine crossroad (4 way intersection)
</code>

For T_Junctions, there is, obviously, no 4th intersection and this is null filled.

Without taking too literal an interpretation, there are some major types of road.

<code>
*asfaltka:bitumen (sealed)
*silnice: Paved
*cesta:   Dirt
</code>

Thus the names of each intersection reflect the road type of that intersection, sometimes resulting in (up to) four identical names.

The overall name of the crossroad itself, tries to reflect the nature of it's makeup thus

kr_asfaltka_asfaltka_t: an bitumen T_Junction

kr_silince_x_cesta: a crossroad of paved and dirt roads.


====== Elevation ======

<code cpp>
 Elevation
 {
    XYPair   GridSize; // 256 x 256 eg
    float    Heights[[GridSize]];
    float    BlueEdgeTerrainHeights[[NoOfBlueFloats]]  ; //Always zero values

        double    ObjectRelativeSize;    // decimal percentage
        String    InstanceName;          // &quot;minimalStrelPos&quot;
        float     RelativeSurfaceElevation;

====== KeyPoint ======

<code cpp>
 KeyPoint
 {
  LongBool  Always1; 
  String    ClassName;  //&quot;Noe_Lany&quot;
  RGBA      AreaColor,OutlineColor;
  ulong     DisplayStyle;
  ShortBool Visible; 
  float     Offset[[2]];  // map relative
  float     Size[[2]];    // 250 x 250.0 eg (widht and height)
  ulong     ID;         // 0,1,2,3,4,5,6....
  BisString TownName;   //&quot;Lipany&quot;, &quot;Hill&quot;
  BisString LocaleType; //&quot;NameCity&quot; NameCityCapital, NameVillage, NameLocal, VegetationBroadLeaf,Hill,Marine,ViewPoint
  BisString ClassText;  // &quot;canOcclude=1; BumbleButt='FlowControl2&quot;; ++=)#4555Semi&quot;
 }
</code>

Each of these locales have a LocaleType. Some of which are:

*NameCity

*NameCityCapital

*NameVillage

*VegetationBroadLeaf (Forest)

There is always a classname associated with this locale,

*Forest_Owls

*Abel_LaTrinite

and in most cases a text name

"La Refuge Des Chassuers"

(Type Viewpoints and Marine eg) do not have names associated with them. There is no &quot;place&quot; in the sea.


====== Background ======

<code cpp>
  Background // this structure has not been seen
  {
       String BackgroundFilename;//&quot;sat_lco.bmp&quot;
       String BackgroundName; //&quot;overlay1&quot;
       float  OffsetXY[[2]];
       float  SizeXY[[2]];
       ulong  Transparency;
       shortBool Visible; // or ulong?
  }
</code>


====== Selection ======

<code cpp>
 Selection
 {
  ushort       strlen;
  char[[]]       SelectionName[[strlen]];  // NOT null terminated
  ulong        nSubSelections;
  SubSelection SubSelections[[nSubSelections]]
 }
</code>

====== SubSelection ======

<code cpp>
 SubSelection
 {
  ulong ObjectId;
  byte  Type;
  byte  Unknown[[7]];
}
</code>


====== Enums ======

====== ObjectClassEnum ======

<code cpp>
  enum ObjectClassEnum
  {
     Natural = 1,
     Artificial = 2,
     Road = 3,
     Forest = 4,
     ArtificialAndDefinedInRoad = 5  
  }
</code>


====== MarkerTypeEnum ======

<code cpp>
  enum MarkerTypeEnum
  {
     Rectangular = 0,
     Elliptical = 1
  }
</code>

As of v60 a rarely used sub structure with ObjTemplates.
