geometry.angle function
Syntax
float geometry.angle(angleType)
Parameters
- angleType (selector)
Selector for the angle calculation.maxSlope Calculates the maximum slope of the shape, relative to the xz-plane, in degrees. azimuth Calculates the azimuth of the direction of the current shape's maximum slope, in degrees. zenith Calculates the difference between 90 degrees (zenith) and the maximum slope.
Returns
Angle of the current shape's geometry, depending on the selector, in degrees.
Description
azimuth is the horizontal angle measured clockwise from the north, i.e. 90 degrees is east, 180 degrees is south and 270 degrees is west. Azimuth is in the range [0, 360[.
The geometry.angle(zenith) function returns the same value as 90 - geometry.angle(maxSlope).
Examples
Cone-->
comp(f) { all : color(geometry.angle(maxSlope) / 90, 0.0, 0.0) Shape. }
Cone-->
comp(f) { all : color(0.5, geometry.angle(azimuth) / 360, 0.5) Shape. }

geometry.isPlanar function
Syntax
bool geometry.isPlanar(tolerance)
Parameters
- tolerance (float)
The tolerance in degrees for deciding if an face is planar or not. The face normal is compared to the edges' crossproduct (''local normal'') at every vertex; if the angle between a ''local normal'' and the face normal is larger than the tolerance the face is non-planar. A reasonable value is 0.25 degrees.
Returns
true if the geometry contains at least one face and all faces of are planar (within tolerance), false otherwise.

Returns
true if the geometry contains at least one face and all faces consist of 4 vertices and contain only right angles, false otherwise. Angles in the range [90-tolerance, 90+tolerance] are considered to be "right".
