Apply forward transformation to mesh vertices

Since R2020a



transformedMesh = applyTransform(mesh,T) applies the forward transformation matrix T to the vertices of the object mesh.


collapse all

Create an extendedObjectMesh object and transform the object by using a transformation matrix.

Create a cuboid mesh of unit dimensions.

cuboid = extendedObjectMesh('cuboid');

Create a transformation matrix that is a combination of a translation, a scaling, and a rotation.

tform = makehgtform('translate',[0.2 -0.5 0.5], ...
    'scale',[0.5 0.6 0.7], ...

Transform the mesh.

transformedCuboid = applyTransform(cuboid,tform);

Visualize the meshes.

Figure contains 2 axes objects. Axes object 1 with title Initial Mesh contains an object of type patch. Axes object 2 with title Transformed Mesh contains an object of type patch.

Input Arguments

collapse all

Extended object mesh, specified as an extendedObjectMesh object.

Transformation matrix applied on the object mesh, specified as a 4-by-4 matrix. The 3-D coordinates of each point in the object mesh is transformed according to this formula:

[xT; yT; zT; 1] = T*[x; y; z; 1]

xT, yT, and zT are the transformed 3-D coordinates of the point.

Data Types: single | double

Output Arguments

Transformed object mesh, returned as an extendedObjectMesh object.
