xdesign.feature

Functions:

Feature(geometry[, mass_atten])

A geometric region(s) and associated materials properti(es).

class xdesign.feature.Feature(geometry, mass_atten=1)

Bases: object

A geometric region(s) and associated materials properti(es). Properties and geometry can be manipulated from this level, but rendering must access the geometry directly.

geometry

Entity

Defines a region where the properties are valid.

mass_atten

scalar

The mass attenuation coefficient of the Feature.

add_property(name, function)

Adds a property by name to the Feature. NOTE: Properties added here are not cached because they are probably never called with the same parameters ever or the property is static so it doesnt need caching.

area

Returns the total surface area of the feature

center

Returns the centroid of the feature.

radius

Returns the radius of the smallest boundary circle

rotate(theta, p, axis=None)

Rotate feature geometry around a line. Rotating property functions is not supported.

translate(x, y)

Translate feature geometry. Translating property functions is not supported.

volume

Returns the volume of the feature
