Vector4¶
A 4D vector using floating point coordinates.
Description¶
A 4-element structure that can be used to represent 4D coordinates or any other quadruplet of numeric values.
It uses floating-point coordinates. By default, these floating-point values use 32-bit precision, unlike float which is always 64-bit. If double precision is needed, compile the engine with the option precision=double.
See Vector4i for its integer counterpart.
Note: In a boolean context, a Vector4 will evaluate to false if it's equal to Vector4(0, 0, 0, 0). Otherwise, a Vector4 will always evaluate to true.
