Plugin Supershape

Installation

After downloading the plugin, simple copy the file supershape.hxt in to the HXT directory your A:M installation .
The plugin is only just for fun , and therefor raises far no claim to completness or accuracy, however it is freeware .

Description

With this plugin you can build a shape with 4 parameters based on the "Superformula" . More information about this formula , calculation, the parameters you can found on the site from Paul Bourke (english) or here Heise online (german) .But more interested is to play with the parameter .

Usage

The plugin is started with RMB->Plug-ins->Wizards->Supershape in a modellingwindow or with selected "Objects" in the pws .

Description
number of cp's
The number of cp's they should be created. In dependence from this , the appearance of the created shapes is changed.(look at this example) . In the preview , you see only a abstracted shape, which is not the same then in A:M , because for the preview I use linearsegment instead of splines.
m
The first parameter for the formula. Meaningful values lie between 0.1 and 20 , but also higher or lower values are possible.
n1
The second parameter for the formula. Meaningful values lie between 0.1 and 100 , but also higher or lower values are possible.
n2
The third parameter for the formula. Meaningful values lie between 0.1 and 100 , but also higher or lower values are possible.
n3
The fourth parameter for the formula. Meaningful values lie between 0.1 and 100 , but also higher or lower values are possible.
Randomize m,n1,n2,n3
With this button you can create randomized values for the formula. The result you can see in the preview .
autoupdate
If this checkbox is activated , the preview is updated automatically, when you change a parameter.
Update Preview
With this button , you can update the preview by hand . It's only needed , if you have a slow machine, where autoupdate takes to many time. Only avaible if autoupdate is not checked.
Match radius
Hereby one specifies, on which radius the produced model is to be scaled. I.e. no point of the model will lie outside of this radius.
OK
End the plugin and create the model/shape.
Cancel
Cancel the plugin and return to A:M without any other action .
Under some circumstands , you can get a preview , looks like the next picture
error
This means , that too large or small values are calculated , which cannot be scaled any longer reasonably. Then is also the OK button deactivated . Remedy creates here a parameter of the formula to decrease/increase (in this example, increase n1 to 0.1)

Here a overview, as the number of cp's affects the appearance of the preview and the model (m = 8, n1 = 0.1, n2 = 1,n3 = 5), in the first column is the number of cp's used
