Coordinate systems

Coordinate system

Currently, the .car files use the following coordinate system for all parameters:

• car x = right & left, negative being left
• car y = forward & back, negative being back
• car z = up & down, negative being down

This coordinate system was picked because it matches the blender coordinates. To use this coordinate system, specify "version = 2" in the .car file.

Coordinate system version 1 (outdated)

Previous to code revision 2196, the .car files all used mixed coordinate systems.

• blender coordinate system
  • car x = right & left, negative being left
  • car y = forward & back, negative being back
  • car z = up & down, negative being down

• .car file: mass positioning (same as blender)
  • car x = right & left, negative being left
  • car y = forward & back, negative being back
  • car z = up & down, negative being down

• .car file: wheel positioning (tested on Front Right wheel)
  • wheel x = forward and back, negative being back
  • wheel y = left and right, negative being right
  • wheel z = up and down, negative being down

• .car file: view positioning (same as wheel)
  • view x = forward & back, negative being back
  • view y = right & left, negative being right
  • view z = up and down, negative being down
