axis distribution function
Description
By default the rotation angle is integrated over the full range the fundamental region allows for the axis in question. minAngle and maxAngle restrict that range, which is what the axis angle sections show: the distribution of the axes of those rotations whose angle falls into a given window. An axis for which the window lies entirely outside the fundamental region contributes zero.
The quadrature keeps its step, not its number of points, so a narrow window is integrated with correspondingly few of them - lower resolution if the values it returns matter to better than a percent.
Syntax
value = calcAxisDistribution(odf, a)
adf = calcAxisDistribution(odf)% only rotations by 20 to 40 degree
adf = calcAxisDistribution(odf,'minAngle',20*degree,'maxAngle',40*degree)Input
| S3F | orientation or misorientation distribution function, SO3Fun |
| a | rotational axis, vector3d |
Output
| afd | axis distribution function, S2Fun |
| value | value of axis distribution function for rotational axis a |
Options
| minAngle | ignore rotations by less than this angle |
| maxAngle | ignore rotations by more than this angle |
| resolution | step of the angle quadrature, 2.5 degree by default |
