rand.inc - Flat Distributions

### 7.12.1 rand.inc - Flat Distributions

`SRand(Stream)`. "Signed rand()", returns random numbers in the range [-1, 1].
Parameters:

- `Stream` = Random number stream.

`RRand(Min, Max, Stream)`. Returns random numbers in the range [Min, Max].
Parameters:

- `Min` = The lower end of the output range.
- `Max` = The upper end of the output range.
- `Stream` = Random number stream.

`VRand(Stream)`. Returns random vectors in a box from < 0, 0, 0> to < 1, 1, 1>
Parameters:

- `Stream` = Random number stream.

`VRand_In_Box(PtA, PtB, Stream)`. Like VRand(), this macro returns a random vector in a box, but this version lets you specify the two corners of the box.
Parameters:

- `PtA` = Lower-left-bottom corner of box.
- `PtB` = Upper-right-top corner of box.
- `Stream` = Random number stream.

`VRand_In_Sphere(Stream)`. Returns a random vector in a unit-radius sphere located at the origin.
Parameters:

- `Stream` = Random number stream.

`VRand_On_Sphere(Stream)`. Returns a random vector on the surface of a unit-radius sphere located at the origin.
Parameters:

- `Stream` = Random number stream.

`VRand_In_Obj(Object, Stream)` This macro takes a solid object and returns a random point that is inside it. It does this by randomly sampling the bounding box of the object, and can be quite slow if the object occupies a small percentage of the volume of its bounding box (because it will take more attempts to find a point inside the object). This macro is best used on finite, solid objects (non-solid objects, such as meshes and bezier patches, don't have a defined "inside", and will not work).
Parameters:

- `Object` = The object the macro chooses the points from.
- `Stream` = Random number stream.
