4.
Select the edge loop around the pasted polygon and the area from where the polygon was cut.
5.
Use the Bridge tool to attach the two sections.
6.
Set the Mode to Curve and increase the Segments until the rounded area is adequately smooth and
rounded.
7.
Select the front polygon and bevel it out to the sidewalk and street.
A sidewalk and street can easily be created using a few bevels. This will allow you to position the camera
a little farther from the structure without positioning it in the middle of open space. At this point, the basic
structure of the entire scene is completed, as shown in
Figure 10-18
.
Some additions will allow you to create
more detail in textures and have options for creating displacement-based geometry.

The model and scene completed at a basic level
Using Subdivision Surfaces in a Polygonal Model
The majority of the models that you create for architectural visualization will be made up of simple poly-
gons. However, subdivision surfaces will be preferable in some areas. Using SubDs can be useful in a in-
stances such as the following:
• Detached geometry that is rounded or needs to have smooth corners
• Geometry that can benefit from sculpting to improve the shape in an organic manner
• Places where displacement maps will be used to add real depth to the surfaces
Smoothed Geometry
Several places in this scene can benefit from the use of subdivision surfaces. The pillars in the front of the
house are relatively smooth, but they can be converted to SubDs so that they will never appear faceted, no
matter how close the camera gets. To convert these pieces of geometry, you will need to make a few edits.
To start, convert the cylindrical section to PSubs by selecting it and pressing Shift+Tab. The form will look
fine, but many of the tight contours will be lost. To sharpen these edges, the weight map can be leveraged
by doing the following:
1.
Select the edge loops that need to be creased.
2.
Select the Subdivision weight map (Lists tab
⇒
Weight Maps
⇒
Subdivision).
