subtri

Below is a demonstration of the features of the subtri function

Contents

Syntax

|[F,V]=coneTriMesh(coneRadius,coneHeight,pointSpacing,nTopMin);

Description

The coneTriMesh function creates a triangulated mesh for a cone with a base radius coneRadius and a height coneHeight. The desired node spacing is set by pointSpacing. The parameter nTopMin sets the number of repeated "pie-segments" used to build the cone, and hence also sets the minimum number of points the tip node is connected to.

Examples

clear; close all; clc;

coneRadius=2;
coneHeight=4;
pointSpacing=0.25;
nTopMin=6;
closeBaseOpt=1;

[F,V,C]=coneTriMesh(coneRadius,coneHeight,pointSpacing,nTopMin,closeBaseOpt);

actualMeanPointSpacing = mean(patchEdgeLengths(F,V))

actualMeanPointSpacing =

    0.2491
