Grlib is an implementation of generative grammars and turtle graphics. The grammars (Lindenmayer systems) are used to produce descriptions of three dimensional objects, and the turtle is used to display them (i.e., generate images in several forms, such as bitmap, PostScript, or OpenGL).
GtkGLMaterialDialogis a GTK+ dialog that can be used to edit 3D-object material properties. It is based on the material properties of OpenGL with diffuse, ambient, specular, emissive colors (RGBA), and a specular coefficient (shininess). The material is previewed by rendering a lit OpenGL sphere in a gtkglarea widget.
HeeksCAD is a CAD application. It can import solid models from STEP and IGES files, draw construction geometry and lines and arcs, create new primitive solids, or make solids by extruding a sketch or by making a lofted solid between sketches. Solids can be modified using blending or boolean operations. Models can be saved as IGES, STEP, and STL. The 2D geometry can be plotted with a printer or to HPGL. DXF files can be imported and exported; lines, arcs, spline, ellipses, and polylines are supported. SVG import has similar capabilities. It is possible to make Add-In modules. The HeeksCNC project provides a CAM add-in, and HeeksPython provides a Python console.
HeeksCNC is a CAM (Computer Aided Manufacturing) add-on module for HeeksCAD. The user can add machining operations. These can then be output to NC code. The NC code is then shown as red and green lines on the screen. The NC code is generated using Python script, so it can be configured for different machines. HeeksCNC uses pycam for the "Zig Zag" operation, libarea for the "Pocket" operation, and libactp for the "Adaptive Roughing" operation.
InnerWorld is an experimental landscape generator running inside Blender 3d. The generator can be used for mesh creation and to populate the virtual world with objects. Mesh generation and procedural object placement can be defined by using a graph editor. Different noise sources and operators can be arranged for procedural content creation. Meshes can be generated from Blender's noise functions, FFT synthesizing, and external gray scaled images acting as height fields.
JCCad is a project to develop a 2D/3D CAD program that can be used to create technical drawings. One of the main goals of this project is to include a plugin system to allow usuaries to make new commands. In this way it will be easy to use the program for any particular task. JCCad provides an easy interface with a command line.
