drawSphere

Draws a sphere around a given point with given radii in x, y and z (if 3D).

All pixels other than in the sphere are untouched. Consider using set(buffer, 0); in advance.

Category: Visualisation

Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clij2_-2.5.0.1.jar.

Usage in ImageJ macro

Ext.CLIJ2_drawSphere(Image destination, Number x, Number y, Number z, Number radius_x, Number radius_y, Number radius_z, Number value);

Usage in object oriented programming languages

Java

// init CLIJ and GPU
import net.haesleinhuepf.clij2.CLIJ2;
import net.haesleinhuepf.clij.clearcl.ClearCLBuffer;
CLIJ2 clij2 = CLIJ2.getInstance();

// get input parameters
destination = clij2.create();
float x = 1.0;
float y = 2.0;
float z = 3.0;
float radius_x = 4.0;
float radius_y = 5.0;
float radius_z = 6.0;
float value = 7.0;

// Execute operation on GPU
clij2.drawSphere(destination, x, y, z, radius_x, radius_y, radius_z, value);

// show result
destinationImagePlus = clij2.pull(destination);
destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(destination);

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
destination = clij2.create();
x = 1.0;
y = 2.0;
z = 3.0;
radius_x = 4.0;
radius_y = 5.0;
radius_z = 6.0;
value = 7.0;

% Execute operation on GPU
clij2.drawSphere(destination, x, y, z, radius_x, radius_y, radius_z, value);

% show result
destination = clij2.pullMat(destination)

% cleanup memory on GPU
clij2.release(destination);

Icy JavaScript

// init CLIJ and GPU
importClass(net.haesleinhuepf.clicy.CLICY);
importClass(Packages.icy.main.Icy);

clij2 = CLICY.getInstance();

// get input parameters
destination = clij2.create();
x = 1.0;
y = 2.0;
z = 3.0;
radius_x = 4.0;
radius_y = 5.0;
radius_z = 6.0;
value = 7.0;

// Execute operation on GPU
clij2.drawSphere(destination, x, y, z, radius_x, radius_y, radius_z, value);

// show result
destination_sequence = clij2.pullSequence(destination)
Icy.addSequence(destination_sequence);
// cleanup memory on GPU
clij2.release(destination);
