3D Coordinates

Olivine supports expressing 3-dimensional coordinates, in fact it pays to understand basic Linear Algebra in order to take full advantage of Olivine's spatial features. However, an elementary script designer can go a long way with just a basic understanding of coordinates in Olivine. It is a good idea to read-up on core types prior to reading this section, it discusses integer and real numbers covered here.

The basic syntax of an Olivine coordinate is < number X, number Y, number Z > where number is any integer or real number, and they each express the x, y and z component respectively. X expresses a location along the east/west axis, Y expresses a location along the up/down axis, and Z expresses a location along the north/south axis.

Here are some examples:

< 0, 5, 7 >
< -4, 6, 8 >
< 0, -0.2, 12.74 >

Predefined Coordinates

Unit vectors are built-in with predefined names, they follow the syntax < name > where name is one of EAST, WEST, NORTH, SOUTH, UP, or DOWN.

• < EAST > is the same as < 1, 0, 0 >
• < WEST > is the same as < -1, 0, 0 >
• < NORTH > is the same as < 0, 0, -1 >
• < SOUTH > is the same as < 0, 0, 1 >
• < UP > is the same as < 0, 1, 0 >
• < DOWN > is the same as < 0, -1, 0 >
