Color Quantities

Visualize color rgb-valued data at the points of a point cloud.

Example: 

#include "polyscope/point_cloud.h"

std::vector<std::array<double, 3>> randColor(points.size());
for (size_t i = 0; i < points.size(); i++) {
  randColor[i] = {{polyscope::randomUnit(), polyscope::randomUnit(), polyscope::randomUnit()}};
}

// visualize
polyscope::getPointCloud(pointCloudName)->addColorQuantity("random color", randColor);

PointCloud::addColorQuantity(std::string name, const T& values)

Add a color quantity to the point cloud.

  • values is the array of colors at points. The type should be adaptable to a 3-vector array of floats. The length should be the number of points in the point cloud.

RGB values are interpreted in the range [0,1].

Color Quantity Options

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

Parameter Meaning Getter Setter Persistent?
enabled is the quantity enabled? bool isEnabled() setEnabled(bool newVal) yes

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