Exercise 10.12

Creating a bump map of a texture

Introduction:

In this exercise, you will work in Adobe Photoshop to create a bump map for a texture of your choice and then use the texture on an object you create in Rhinoceros.

Part 1:

  1. Please find a texture image you would like to work with. The image can be from our course website (look under Resources>Collage Textures) or you can find them online (try http://www.cgtextures.com/).
  2. Follow Photoshop Tutorial 1.20 to create a bump map for your texture. This will be demonstrated in lecture today.
  3. Make sure to save both your original texture (Brick.jpg) and the bump file (Brick_bump.jpg) to your flash drive. You may wish to create a special folder for textures as you will likely re-use these in your future modeling.

Part 2:

  1. In Rhinoceros, create a simple object that will showcase your texture (If you have a texture that belongs on a wall, create a wall, etc.).
  2. Apply your texture map to each surface of your object (Follow Rhino Tutorial 5.32)
  3. Now apply your bump map to each surface of the object (Follow Rhino Tutorial 5.33)
  4. Create a simple directional light to showcase your texture (Follow Rhino Tutorial 5.17)

Part 3:

  1. Render your simple object in a view that showcases your new texture & bump map. Post this image to the course website as well as your original texture image and your bump map image. Note: If you used an image found online, please post a link to the website where you found it next to the original image.
