ImageDev

RandomSphereImage3d

Creates synthetic spheres in a binary image.

Access to parameter description

The RandomSphereImage3d algorithm creates a binary image containing a random distribution of spheres. The sphere radius range, distance, type of distribution, and number are parameters of the algorithm.

The following image is an example of the result with the default parameters:

Class Syntax

Parameters

Class Name RandomSphereImage3d

Parameter Name Description Type Supported Values Default Value
input
imageSize
The X, Y, and Z size in voxels of the output image. Vector3i32 >0 {100, 100, 100}
input
sphereNumber
The number of spheres to generate. Int32 >=1 5
input
distribution
The distribution type of the sphere radii.
UNIFORM The radius distribution is uniform (each radius of the range has an equiprobability to occur).
GAUSSIAN The radius distribution is Gaussian (the mean radius of the range is much more represented than the minimum and maximum radii).
Enumeration UNIFORM
input
radiusRange
The minimum and maximum radius in voxels of the spheres (for Uniform distribution) or mean and standard deviation (for gaussian distribution). Vector2i32 Any value {10, 20}
input
distance
The minimum distance between two sphere centers. Int32 >=0 40
output
outputBinaryImage
The output 3D binary image. Image nullptr
