Sample

Category

Realization

Function

Samples the points of a field (surface or volume).

Syntax


samples = Sample(manifold, density);

Inputs

Name Type Default Description
manifold field none the surface or volume to be sampled
density integer 100 approximate number of samples

Outputs

Name Type Description
samples field a set of samples of the field

Functional Details

This module samples a specified field at a set of more or less uniformly spaced points.

manifold

is the field to be sampled.

density

is the approximate number of output samples.

Note: Any components in the original field (manifold) that are position or connection dependent are mapped onto the output samples. In either case, the component in the output field will be position dependent ("dep" "positions"). (Because the output of Sample is a set of unconnected positions, you cannot use mapped samples as input to modules that need to interpolate values, such as DivCurl or MapToPlane).

Components

Creates a new "positions" component. All other components, except for "connections," are propagated to the output.

Example Visual Programs
