Origin
Origin is the 0,0,0 point where the X, Y, and Z axes intersect.
A coordinate system assigns an arbitrary point in space as the origin, and sets
each axis at that point to zero.
In the
world coordinate system on page 7975 , numbers increase from the origin
to the right along the X axis, upward along the Y axis, and away from you on
the Z axis. Numbers decrease (–1, –2, –3, and so on) to the left along the X
axis, downward along the Y axis, and toward you along the Z axis. The distance
between each whole number is called a unit of measurement (a 3ds Max unit).
You can combine the measurements of all three axes to mark specific locations
in 3D space. The combined measurements are called coordinates. Thus, at the
origin, the coordinates are X=0, Y=0, Z=0, which can be expressed more simply
as the vector (0,0,0).
From the origin, the coordinates at a location 100 units to the right, 150 units
up, and 60 units away are X=100, Y=150, Z=60, or (100,150,60).
