Random 3D Coordinate Generator

Generates a random three-dimensional coordinate point (x, y, z), with each axis independently drawn as a whole number from -100 to 100 so the point is spread uniformly through the cube those limits describe — useful for placeholder 3D data in games or graphics, and for geometry practice involving three axes at once.

How this generator works

Three whole numbers are drawn independently, each from −100 to 100, giving a point uniformly distributed over the integer positions inside that cube. Uniform in a box is worth stating plainly because it is not uniform in a sphere: points drawn this way and then normalised onto a sphere's surface bunch towards the directions of its corners, which is a well-known way to get a biased set of directions.

Limitations and good to know

Whole numbers only, on a fixed −100 to 100 range for every axis; there is no control for the bounds or for decimal coordinates.
Uniform within the bounding box, so the corners are as well represented as the middle. That is right for a volume and wrong for a direction.
No coordinate system or handedness is implied — whether y or z is up is a convention of whatever you paste this into.
The three axes are drawn independently, so nothing here produces points on a surface, along a path, or at any fixed distance from the origin.
