Exercise One

First, grab the above image by putting your mouse cursor over the image and pressing the right mouse button. This will bring up a menu with one of the choices being "Save Picture As". Click on this choice and save the image to a directory.

Second, bring the image into a paint program and calculate the mapping coordinates of the triangle part of the image (hint: use the red dots as your coordinate points ;^) as described in the main page for this tutorial.

Third, write a VRML 2.0 file with an IndexedFaceSet that resembles the triangle pictured above. Now use the mapping coordinates you got in step two to map the image on your triangular face.

Neat, huh?

Exercise Two

Now, try this one.
