Scalar Quantities

Visualize scalar valued data at the nodes or edges of a curve network.

curve network scalar demo

Example:

#include "polyscope/curve_network.h"

std::vector<double> xC(nodes.size());
for (size_t i = 0; i < nodes.size(); i++) {
  xC[i] = nodes[i].x; // (use the x coordinate as sample data)
}

// visualize
polyscope::getCurveNetwork(curveNetworkName)->addNodeScalarQuantity("sample value", xC);

CurveNetwork::addNodeScalarQuantity(std::string name, const T& values, DataType type = DataType::STANDARD)

Add a scalar quantity to the nodes of the curve network.

values is the array of scalars at nodes. The type should be adaptable to a float scalar array. The length should be the number of nodes in the curve network.

CurveNetwork::addEdgeScalarQuantity(std::string name, const T& values, DataType type = DataType::STANDARD)

Add a scalar quantity to the edges of the curve network.

values is the array of scalars at edges . The type should be adaptable to a float scalar array. The length should be the number of edges in the curve network.

Scalar Quantity Options

These options and behaviors are available for all types of scalar quantities on any structure.

Parameter	Meaning	Getter	Setter	Persistent?
enabled	is the quantity enabled?	`bool isEnabled()`	`setEnabled(bool newVal)`	yes
color map	the color map to use	`std::string getColorMap()`	`setColorMap(std::string newMap)`	yes
map range	the lower and upper limits used when mapping the data in to the color map	`std::pair<double,double> getMapRange()`	`setMapRange(std::pair<double,double>)` and `resetMapRange()`	no
isolines enabled	are isolines shaded (default=`false`)	`bool getIsolinesEnabled()`	`setIsolinesEnabled(bool newVal)`	yes
isoline width	width of isoline stripes, in data units	`float getIsolineWidth()`	`setIsolineWidth(float newVal)`	yes
isoline darkness	darkness of isoline stripes (default=`0.7`)	`float getIsolineDarkness()`	`setIsolineDarkness(float newVal)`	yes

(all setters return this to support chaining. setEnabled() returns generic quantity, so chain it last)
