This is the OpenTeddy cartoon head tutorial. It shows you some of the basic features of the software.

MAC USERS: If your mouse has only one button, your single button is the LEFT mouse button. You can DOUBLE-CLICK the LEFT button instead of clicking the RIGHT mouse button. You can also SHIFT-DRAG the LEFT mouse button or also a very slow DOUBLE-CLICK of the LEFT button where the second click is followed by a drag instead of dragging the MIDDLE mouse button.

	Use the LEFT mouse button to draw as silhouette of the head. If you make a mistake you can press the ESCAPE KEY in order to cancel the stroke and start over.
	Click the RIGHT mouse button to turn your silhouette into a surface object. Note that the surface is blue- this means that it is currently selected. You can inspect your model by holding down the MIDDLE mouse button, and dragging. If you don't like your model, you can press the BACKSPACE KEY and start over again. This deletes all selected surfaces.
	Press the I KEY to simplify the model. In this example the I KEY is pressed twice. This operation currently is somewhat slow. You can also hold down CONTROL while pressing the I KEY to use a faster, but less accurate simplification method.
	Now, use the MIDDLE mouse button to rotate the head to the front. Use the LEFT mouse button to draw a triangle for a nose.
	Press the RIGHT mouse button to project your triangle onto the surface. Note that this will only work if one surface is selected (colored blue.)
	Again use the MIDDLE mouse button to rotate the head to the side, so that the triangle you drew is now parallel to the direction you're looking in.
	Starting at a point near the top of the triangle, draw a nose curve with the LEFT mouse button. End the curve near the bottom of the triangle.
	Press the RIGHT mouse button to complete your nose. As you can see, the surface is extruded where you drew on it.
	Rotate over to the front again, and again draw with the LEFT mouse button.
	Again press the RIGHT mouse button to project your stroke.
	Similar to the nose, draw a curve from the top of the mouth going left, and end near the bottom of the mouth with the LEFT mouse button. As you can see, this feature allows you to make indentations as well as portrusions.
	You can again inspect your model to see how it looks with the MIDDLE mouse button.
	Now, without using the LEFT mouse button (if you have pressed the LEFT mouse button, you can use the ESCAPE KEY to cancel your stroke.) Click the RIGHT mouse button around where you'd like to put an eye. A green cursor point will appear where you clicked. You can use the MIDDLE mouse button and see that this cursor follows the head around.
	Press the ESCAPE KEY to unselect the shape. The green cursor stays where you clicked.
	Now, use the LEFT mouse button to draw an eye.
	Click the RIGHT mouse button to complete the shape.
	Now, with the RIGHT mouse button, click on a place for the other eye to go.
	Press the ESCAPE key again to unselect everything.
	Same as the right eye, use the LEFT mouse button to draw the left eye.
	Click the RIGHT mouse button to complete the shape.
	Now, we can take all these separate shapes and join them (because they are overlapping.) With the RIGHT mouse button, click on the other eye. It will turn blue to indicate it is also selected.
	With the RIGHT mouse button, click the head. It will also become selected. Press the J KEY to join all the selected surfaces. They are now one surface. You may want to press the I KEY several times more to simplify the mesh so that it is better prepared for quick rendering if you are using the mesh for example, for a game.

Press the S KEY to save your finished object to the file "ot.obj"- Wavefront format. You can now import this mesh in Blender, or your favorite skinning program.

Note that the save feature will only save one of your surfaces currently. Later implementation will allow you to save any number of them.
