§ 12.11.87 - Spherize

Note: Only available in the OS X (MacOS) version.

Scripting command: spherize [width=8...n] [height=8...n] [maptofront=0...1] [material=0...4] [ambient=0...1.0] [scale=0.1...1.5] [assign=0...1] [xtranslate=-100...100] [ytranslate=-100...100] [rotation=-100...100] [threads=1...n]

Note: All available scripting operations are listed on the Script operator page.

The spherize operator uses iToolBox's ray tracing engine to wrap the action image around a sphere, optionally over a plane consisting of the origin image.

When the ray trace is complete, the Load button will become available, and you can load the result in.

Note: The reason the generated image is loaded via the Load button is because for larger raytraces, generation can take more time than you'd probably want to have iToolBox itself wait for. This way, generation occurs in the background and you can go on about other work as needed.

X shift allows you to move the sphere left and right.

Y shift allows you to move the sphere up and down.

Rotation allows you to rotate the sphere; you'd only use this when  Map to Front is not checked.

 Material    allows you to select the surface characteristics of the material the sphere consists of.

 Map to Front causes the action image to be stretched only as much as required to cover the visible portion of the sphere.

Threads lets you select how many cores are to be put to work generating the raytrace. The more cores you assign, the faster the job will complete.

 Over Origin, when checked, will generate a plane behind the sphere that has the origin image mapped to it.

Tip: If you're wrapping multiple images around a sphere, you might want to check the  Drops become origin image checkbox in the Preferences dialog so that any image you drag into iToolBox immediately becomes the origin image.
Note: The raytracing process uses floating point operations, so hyperthreaded cores that do not have floating point capability will not significantly speed up raytraces. However, iToolBox will let you assign all of your available cores if you like; there will be some decrease in generation time.

Width sets the width of the generated image.

 Y→X, when checked, will set the Height of the result equal to the Width when the Height is changed.

Height sets the height of the generated image.

Ambience sets the amount of ambient light on the portion of the sphere that is not directly exposed to the lighting. This interacts strongly with the  Material    selection.

Scale controls the size of the generated sphere.

The Load button becomes available when the raytrace is complete. Pressing it will load the image into iToolBox.
