tri2quad

Below is a demonstration of the features of the tri2quad function

Syntax
Description
Examples
Example 1: Converting a triangulated surface to a quandrangulated surface
Example 2: Using incentres rather than triangle centres

clear; close all; clc;

Syntax

[Fq,Vq]=tri2quad(Ft,Vt);

Description

Tris func

Examples

Plot settings

fontSize=15;

Example triangulated surface

[F,V]=stanford_bunny;

Example 1: Converting a triangulated surface to a quandrangulated surface

Convert triangular faces to quadrilateral faces

[Fq,Vq]=tri2quad(F,V);

Visualisation

cFigure;
subplot(1,2,1);
title('Triangulation','FontSize',fontSize);
gpatch(F,V,'rw','k');
set(gca,'FontSize',fontSize);
axisGeom;
camlight('headlight');

subplot(1,2,2);
title('Quadrangulation','FontSize',fontSize);
gpatch(Fq,Vq,'gw','k');
set(gca,'FontSize',fontSize);
axisGeom;
camlight('headlight');

drawnow;

Example 2: Using incentres rather than triangle centres

Convert triangular faces to quadrilateral faces

centerType=2;
[Fq,Vq]=tri2quad(F,V,centerType);

Visualisation

cFigure;
subplot(1,2,1);
title('Triangulation','FontSize',fontSize);
gpatch(F,V,'rw','k');
set(gca,'FontSize',fontSize);
axisGeom;
camlight('headlight');

subplot(1,2,2);
title('Quadrangulation','FontSize',fontSize);
gpatch(Fq,Vq,'gw','k');
set(gca,'FontSize',fontSize);
axisGeom;
camlight('headlight');

drawnow;
