Description

Description:
PositionCameraToWorld.jpg
Transforms position from camera coordinate space to world coordinate space. Camera axes are relative to camera orientation. x axis goes from left of the camera to right of the camera, z axis goes from underneath the camera to above the camera and y axis goes from back of the camera to where the camera is looking.
Groups:
Camera ControlPositions

Syntax

Syntax:
positionCameraToWorld cameraPos
Parameters:
cameraPos: PositionRelative - Relative camera position, format [x, z, y]
⚠
Note that y and z for this command are swapped around, which is different from your usual model space coordinates format
Return Value:
Array - Camera world position, format PositionAGL

Examples

Example 1:
_worldPos = positionCameraToWorld _cameraPos;
Example 2:
Example demonstrating reversed y and z: player setDir 0; //assuming player is looking forward hint str [[[positionCameraToWorld]] [0,0,0], positionCameraToWorld [0,0,1]]; //[[2481.35,5671.21,1.51395],[2481.35,5672.21,1.46955]]

By measuring the distance between the camera and the player one can determine whether 1st-person or 3rd-person view is being used: if ((positionCameraToWorld [0,0,0] distance player)>2) then {hint "3rd person"} else {hint "1st person"};

The camera coordinate system is different from the model coordinate system: when modelToWorld uses [x, y, z] then positionCameraToWorld uses [x, z, y]. So for a steady camera the following is true: positionCameraToWorld [5,10,15] == _camera modelToWorld [5,15,10];

When over land, the position returned is in format PositionATL, and over sea, PositionASLW.
