K-3D is free-as-in-freedom 3D modeling and animation software. It features a plugin-oriented procedural engine for all of its content, making K-3D a very versatile and powerful package. K-3D excels at polygonal modeling, and includes basic tools for NURBS, patches, curves and animation. This requires gtkglext, libsigc++, glibmm, cairomm, pangomm and gtkmm (building / installing in this order should work fine) Optional packages: graphviz, gtksourceview, libgnome and OpenCASCADE.
