Introduction.- An idealized world out of simple elements: Points, straight lines and circles in the drawing plane. Special points inside the triangle. Elemental building blocks in space. Euclidean space. Polarity, duality and inversion. Projective and non-euclidean geometry.- Projections and shadows - Reduction of the dimension: The principle of the central projection. Through restrictions to parallel projection and normal projection. Assigned normal projections. The difference about technical drawing.- Polyhedra: Multiple faced and multi-sided: Congruence transformations. Convex polyhedral. Platonic solids. Other special classes of polyhedral. Planar sections of prisms and pyramids.- Curved but simple: Planar and spatial curves. The sphere. Cylinder surfaces. The ellipse as a planar section of a cylinder of revolution.- More about conic sections and developable surfaces: Cone surfaces. Conic sections. General developables (torses). About maps and "sphere developments". The "physical" reflection in a circle, a sphere and a cylinder of revolution.- Prototypes: Second-order surfaces. Three types of spatial points. Surfaces of revolution. The torus as a prototype for all other surfaces of revolution. Pipe and duct surfaces.- Further remarkable classes of surfaces: Ruled surfaces. Helical surfaces. Different types of spiral surfaces. Minimal surfaces.- The endless variety of curved surfaces: Mathematical surfaces and free-form surfaces. Interpolating surfaces. Bézier- and B-spline-curves. Bézier- and B-spline-surfaces. Surface design, only differently.- Photographic image and individual perception: The human eye and the pinhole camera. Different techniques of perspective.

Rezensionen
From the reviews: "A marvelous book, abundantly illustrated. It contains many applications ... all with an underlying geometric flavor. ... What is immediately striking at first glance is the luxury of this publication: thick paper with hundreds of colorful glossy pictures and graphs. If you love books and geometry, this is one to fall in love with. ... This picture book is more than just a coffee-table book ... of a math department, because it contains not only many pictures, but also gives theorems and proofs(!)." (A. Bultheel, The European Mathematical Society, February, 2013)
