	0.	Basics - What's possible and what you need! An overview on what is possible and what it needs. Basic sample files and include file "analytical_g.inc"
	1.	Points in a 3D System of Coordinates Methods for unequivocal visualization of points in a 3d system of coordinates.
	2.	Line Sections, Straight Lines, Vectors, Distance Markers The representation of line sections, straight lines, vectors, and distance markers.
	3.	Surfaces and Planes Triangles, parallelograms, planes by parameters and plane by normalvector.
	4.1	Output of Results and Captions How to make an output of the calculated results and how to add a caption to objects.
	4.2	Calculating Points of Intersection How to calculate points of intersections between straight lines and planes or other objects and print the results in the image.
	5.	Circles Circle, circle inside a triangle, circumcircle - circle around a triangle.
	6.1	Solids I - Tetrahedron Tetrahedron defined by 4 corners, tetrahedron defined by a starting point and 3 vectors.
	6.2	Solids II - Parallelepiped Parallelepiped defined by the corners, parallelepiped defined by a starting point and 3 vectors.
	6.3	Solids III - Round Solids Sphere, ellipsoid, cylinder, cone.
	7.	An Overview by Table The most important commands of POV-Ray and of my include file "analytical_g.pov" and a list of the colors of my template file for a quick orientation.
	8.	Vector Analysis with POV-Ray Table of most important spellings, arithmetic rules and expressions of vector analysis and vector functions in POV-Ray.
	9.	Righthanded and Lefthanded Systems of Coordinates and the Cross Product Basics on the handyness of systems of coordinates
