This engine creates a set of randomly distributed points in a closed surface.

Contents 1 Input Data's 2 Output Data's 3 Important Parameter 4 Examples

Input Data's

• triangles

list of triangles of the closed surface

• points

list of positions of the previous triangles

• surfaceVertices

list of positions

Output Data's

• inPoints

list of generated points, which are inside the closed surface.

Important Parameter

• numberOfInPoints

desired number of generated points

• minDistanceBetweenPoints

minimum distance between 2 points (put -1 for true randomness)

• numberOfTests

testing if a point is in a closed surface consists in seeing if the point and a random direction intersects the surface. Obviously, if the direction is not very convenient, the result will be not correct. So we can put a certain number of tests to be valid.

• randomSeed

if you want the same pattern each time you run the test, fix the seed to have always the same results.
