Units and Coordinates in Holodeck¶
Holodeck uses meters for units and a left-handed coordinate system for all locations, distances, and offsets.
Coordinate System¶
Since Holodeck depends on Unreal Engine, we use a left handed coordinate system
with positive z
being up.
This is something baked deep into the engine that we
can’t easily change.
So, when you need to specify a location in Holodeck, the format is as follows
[x, y, z]
where:
Positive
x
is forwardPositive
y
is rightPositive
z
is up
Remember that the units for [x, y, z]
are in meters (Unreal Engine
defaults to centimeters, we’ve changed this to make things a bit easier).
