Chapter 13: Modeling with Polygons and Patches

Caution
With the Tri Patch’s object color set to white, telling when it is selected can be difficult. n
4. Repeat Steps 2 and 3, alternating which color comes first until the entire 8×8 checkerboard is
complete.

Tip
An easier way to accomplish the checkerboard would be to create the first two squares and then to use the Array
dialog box to create the rest. Find out more about the Array dialog box in Chapter 8, “Cloning Objects and
Creating Object Arrays.” n
Figure 13.34 shows the completed checkerboard.

Editing Patches

Creating and working with patches is easy, but because they are always flat, they have limited functionality.
The key to making patches really useful is to convert the object into an Editable Patch object. Any type of geo-
metric object can be converted to an Editable Patch object. Even patch grids created with the Quad Patch and
Tri Patch buttons described earlier need to be converted before they can be edited at the subobject level.
