Preface BlenderCourse teaches you about 3D modelling and provides you short tutorials about a specific subject. The main thought is: Just do it! During different courses you learn various techniques. If necessary there is a small instruction, but in my opinion you learn best when doing the exercise by yourself. BlenderCourse is intended for everyone who can use a computer. This means you understand terms as “double click” and “tab-key”. You do not need any 3D-modelling knowledge; the terms used will be explained during the different courses. If you see an error or something is not clear, I want to ask you to contact me through [email protected]. More Blender Course material can be found at http://www.blendercourse.com. Have fun with Blender Course! Bas van Dijk Wijdewormer, the Netherlands, January 2007

A text between < and > means a key on the keyboard. Example: Press <Enter> to confirm the operation.




A combination of more than one key will be written with the plus sign (+). Example: Press + to exit the program.




A button on the screen will be written between [ and ]. Example: Click at [OK] to close the window.
