Color Quantities
Visualize color rgb-valued data at the elements of a surface mesh.
Example: visualizing random colors at faces
#include "polyscope/surface_mesh.h"
// Make some random colors
std::vector<std::array<double, 3>> fColor(nFaces);
for (size_t iF = 0; iF < nFaces; iF++) {
std::vector<size_t>& face = faceIndices[iF];
fColor[iF] = {{polyscope::randomUnit(), polyscope::randomUnit(), polyscope::randomUnit()}};
}
// Visualize
polyscope::getSurfaceMesh("name")->addFaceColorQuantity("fColor", fColor);
Add colors to elements
SurfaceMesh::addVertexColorQuantity(std::string name, const T& values)
Add a color quantity defined at the vertices of the mesh.
values
is the array of colors at vertices. The type should be adaptable to a 3-vector array offloat
s. The length should be the number of vertices in the mesh.
RGB values are interpreted in the range [0,1]
.
SurfaceMesh::addFaceColorQuantity(std::string name, const T& values)
Add a color quantity defined at the faces of the mesh.
values
is the array of colors at faces. The type should be adaptable to a 3-vector array offloat
s. The length should be the number of faces in the mesh.
RGB values are interpreted in the range [0,1]

Options
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)
