Texture MappingFor most of the time we
can't just use reflection and refraction to create a material for an object. For
example: stone, wood, painting, package, sticky back paper and textile. We must
use some texture maps to create these materials. Below are some examples of
using texture map for rendering.
Open file: Texture-Mapping_01.skp. Render
the scene directly after opened and you will get the result as the image on the
top (below) with only reflection material applied to it. Image on the bottom is the result of
applying texture maps.
1. Assign materials to the objects by
using the paint bucket and Material Editor in SketchUp. You will notice the
texture mapping is not to scale and not properly oriented by default.
2. Right-click on one surface, select
Texture>Position to adjust the texture rotation and scale.
3. Scale and rotate the texture map as
desired. Right-click and select done.
4. Click on the View menu and select
Hidden Geometry in SketchUp. Repeat texture adjustment for one face of cylinder
and sphere.
5. Select the eye dropper tool from the
Materials rollout to sample the adjusted textures.
6. Using the selection tool, select all
the geometry to be updated with the adjusted texture. Once selected, select the
paint bucket and apply the texture to the geometry.
7. Open the Material Editor and you will
see the materials already created.
8. You can add reflection or refraction
layer. The image below was rendered using reflection layer.
