Scalar Quantities

Visualize scalar (real or integer)-valued data at the points of a point cloud.

Example:

#include "polyscope/point_cloud.h"

std::vector<double> xC(points.size());
for (size_t i = 0; i < points.size(); i++) {
  xC[i] = points[i].x;
}

// visualize
polyscope::getPointCloud(pointCloudName)->addScalarQuantity("xC", xC);

PointCloud::addScalarQuantity(std::string name, const T& values, DataType type = DataType::STANDARD)

Add a scalar quantity to the point cloud.

values is the array of scalars at points. The type should be adaptable to a float scalar array. The length should be the number of points in the point cloud.

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)
