This is a documentation video of a 3D prototyping lesson. This video had documentad three different 3D prototyping exercise. Exercise 1: paper slices, Exercise 2:polyrocks and Exercise 3: Abstract landscape. Exercise 1: Paper Slices. Using a 3D object slicing technique, computer based 3D object will be assembled to a physical model by paper cutouts. Exercise 2: Create a 3D polygonal object with at least 16 faces. Exercise 3: ‘Abstract Landscapes’ Prepare a software based 3D Model using a height map technique and prepare the model in .stl format for printing.
