vrifs2patch will be removed in a future release. For more information, see Version History.

Syntax

vrifs2patch(ifs)

Description

vrifs2patch(ifs) converts the ifs array of existing IndexedFaceSet nodes to MATLAB® patch objects.

Note

This function converts only geometry and color data of the source IndexedFaceSet node.

This example uses:

Open Live Script

This command converts three IndexedFaceSet nodes to MATLAB® patch objects.

Open virtual world containing an IndexedFaceSet node.

w1 = vrworld('*sl3dlib/objects/Components/Shapes/Torus_High.wrl');
open(w1);

View the virtual world as a virtual figure.

vrfig1 = vrfigure(w1, ...
           'Name', 'Virtual world containing source IndexedFaceSet node', ...
           'CameraBound', 'off', ...
           'CameraPosition',[0 40 0], ...
           'CameraDirection',[0 -1 0], ...
           'CameraUpVector',[0 0 -1]);
vrdrawnow;

Figure Virtual world containing source IndexedFaceSet node contains objects of type hgjavacomponent, uimenu, uipanel, uitoolbar.

Convert the IndexedFaceSet a MATLAB patch and show it.

figure('Name', 'Resulting patch');
tp = vrifs2patch(w1.torushi.children.geometry);

Figure Resulting patch contains an axes object. The axes object contains an object of type patch.

Change the patch color, show the axes grid, rotate the camera, and enable mouse rotation.

tp.FaceColor = 'red';

axs = gca;
axs.XGrid = 'on';
axs.YGrid = 'on';
axs.ZGrid = 'on';

camorbit(45, -20);

rotate3d on

Figure Resulting patch contains an axes object. The axes object contains an object of type patch.

Input Arguments

R2023b: To be removed

The vrifs2patch will be removed in a future release. Instead, use sim3d classes and Simulation 3D blocks to interface MATLAB and Simulink® with the Unreal Engine® 3D simulation environment. To get started, see Create 3D Simulations in Unreal Engine Environment.
