UM 2009-08-27 This directory treats matter which is related to geometry and which comes in two versions 2D and 3D. Setting of macros CPM_DIMDEF2, CPM_DIMDEF3 allows to relieve the compiler from the task to create both versions (which was a problem with compilers in the past). See file cpm1/include/cpmdimdefwrc.h. Topics are: 1. Visualization (Conversion of structures in space into images) cpmcamera 2. Vectors, points, reference system, rotations, translations, ... cpmdim 3. geometric objects cpmshapes 4. graphical objects in space cpmlineart (line art) cpmvectorgraphics 5. fields (in the sense of physics) cpmfield
