Introduction

Pew are Visitor's project files. Visitor is BI's tool for creating Islands.

Visitor is a Gui tool interface 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

• POSEW59 and
• POSEW60

there are only a few subtle differences to their makeup.

Legend

Little endian byte order, lsb first for numeric values, text is stored in Big endian byte order.

XYPair

XYPair
{
 ulong x,y; // normally associated with cell sizes
}

RGBAColor

RGBAColor
{
 byte r,g,b,a; // // 0xFF:FF:FF:FF means 'default'
}

• RGBA colors correspond to Microsoft's D3DCOLORVALUE
• They normally come in pairs innside the pew structures

String

String
{
 ulong  Length;
 Asciiz Characters;// null terminated regardless. 

Length always =strlen(Characters)+1;

This is a pre-calculated convenience to reduce load times (and skip over the variable length block).

File Format

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

Broadly speaking, there are a few basic road types

• asfalt bitumen.
• silnice Paved
• cesta dirt

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

• 3 'straight' models, approximately 6,12, and 25 meters long respectively.
• 4 'curved' models, 25,50,75 and 100 meters long.
• 1 'terminaton type.

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

 String    Name;	      //kr_asfaltka_asfaltka_t.
 ushort    Type              //1 or 3

 shortBool CanChangeBankAngle;
 ulong     ObjectID;
 String    Intersections[4]; //"asfaltka","silnice","cesta",Type=3 "silnice" else ""
}

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

• Type 1: A T_Junction (3 intersections)
• Type 3: A Genuine crossroad (4 way intersection)

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.

• asfaltka:bitumen (sealed)
• silnice: Paved
• cesta: Dirt

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.

There is always a classname associated with this locale,

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 "place" in the sea.
