Applying geometric transformation

In this section, we start to move the graphical shapes in the 3D space. The operations are translation, rotation, and scale. Each operation comes with two versions. They are: translate, translateXYZ, rotate, rotateXYZ, scale, and scaleXYZ. In this book, we focus on the use of translateXYZ, rotateXYZ, and scaleXYZ. Readers can use the help menu to check the usage of translate, rotate, and scale.

Performing translation, rotation, and scaling

Create an empty patch and save it with name gem005.pd in your folder. Put the gemwin object, create and destroy messages, and the toggle box for rendering. In addition, put a gemhead object with a cube 3D object.

Between the gemhead and the cube objects, insert a translateXYZ object. The translateXYZ operation moves the object along each of the three axes. The three number boxes control the magnitude of the movement:

Note that the cube changes position and renders with a perspective view:

For rotation, insert the rotateXYZ...
