Detailed Description

Scalar computer backed by local contour-side counts.

This computer projects scalar attributes from its finite-window computation. The public attribute pipeline/topology backend invokes it for CONTOUR_* requests.

The finite-window computation is performed once and the following attributes are materialized as projections of the same bucket:

• CONTOUR_PIXELS: pixels with at least one exposed 4-neighbour side;
• CONTOUR_PERIMETER: total exposed 4-neighbour sides;
• CONTOUR_SIDE_NORTH, CONTOUR_SIDE_WEST, CONTOUR_SIDE_EAST, CONTOUR_SIDE_SOUTH: directional exposed-side counters.

Member Function Documentation

compute()

template<std::floating_point Real>

static void mmcfilters::attributes::computers::ContourSideAttributeComputer::compute ( const AttributeComputeContext< Real > &  context )

inlinestatic

Computes requested contour-side scalar attributes for live nodes.

The output buffer is indexed by dense internal node id and interpreted by context.attrNames. The method computes the finite-window contour-side counts once, then projects only the requested scalar columns. Altitude and dependencies are ignored because contour-side counts depend only on topology and regular-grid support.

Parameters

context

Operation context or diagnostic label.

Definition at line 91 of file ContourSideAttributeComputer.hpp.

computeUnitRows()

template<std::floating_point Real>

static void mmcfilters::attributes::computers::ContourSideAttributeComputer::computeUnitRows ( const UnitAttributeComputeContext< Real > &  context )

inlinestatic

Materializes contour-side attributes for one-pixel unit supports.

A one-pixel unit support contributes one contour pixel and four exposed sides, one in each cardinal direction.

Parameters

context

Operation context or diagnostic label.
