transform

Apply rigid transformation to surface mesh

Since R2022b

Syntax

transform(mesh,tform)

Description

transform(mesh,tform) applies the rigid 3-D transformation specified by tform to the surface mesh mesh.

Examples

Apply Rigid 3-D Transformation to Surface Mesh

Define mesh vertices for a surface mesh.

vertices = [1 -1  1; 1 1 1; -1 1 1; -1 -1 1; ...
            1 -1 -1; 1 1 -1; -1 1 -1; -1 -1 -1];

Define the mesh faces using the vertices.

faces = [6 2 1; 1 5 6; 8 4 3; 3 7 8; 6 7 3; 3 2 6; ...
         5 1 4; 4 8 5; 4 1 2; 2 3 4; 7 6 5; 5 8 7];

Create and display the surface mesh.

mesh = surfaceMesh(vertices,faces);
surfaceMeshShow(mesh)

Define rotation and translation values, then use them to generate a transformation matrix.

theta = 30; 
rotationMat = [cosd(theta)  sind(theta) 0;
              -sind(theta) cosd(theta) 0;
                  0            0       1];
translationVector = [2 0 0]; 
tform = rigidtform3d(rotationMat,translationVector);

Apply the rigid transformation and visualize the output.

transform(mesh,tform);
surfaceMeshShow(mesh)
