patchNormPlot

Below is a demonstration of the features of the patchNormPlot function

Contents

clear; close all; clc;

Syntax

[hp]=patchNormPlot(F,V,a,pathType);

Description

Visualizes surface normals for all faces F with vertices V.

Examples

testCase=2;
switch testCase
    case 1 %Single element square 1x1
        z=2;
        V=[0 0 0; 1 0 0; 0 1 z; 1 1 0];
        F=[1 2 4 3];
    case 2 %Sphere triangles
        r=1;
        n=2;
        [F,V]=geoSphere(n,r);
end
