Chapter 5 Rendering in SketchUp
Example 5.3: Texturing Curved Surfaces
Curved surfaces have traditionally posed a problem for texturing in SketchUp (tiled textures,
on the other hand, tile well on curves, too). Although it is possible to apply a continuous texture
over a curved surface, positioning using the pin method previously described does not
work on those surfaces (because they are made up of surface “facets”).
If you need to align a tiled texture on a curved surface, turn on Hidden Geometry in
SketchUp and align the texture on one of the faces. Then, sample and paint the aligned
texture onto all other faces.
TIP
One method to deal with this is to add a planar object close to a curved object, place the
texture on the planar object, position it there, and sample and paint the projected texture
onto the curved object. Figure 5.78 shows how a texture would look after this operation.
Figure 5.78: Placing a projected texture onto a curved object
As you can see, the texture looks good on the right side of the curve but stretches significantly
on the left side. Therefore, this method works best for curved objects that feature
only gentle slopes.
