Meshgen is a tool to simplify the creation of procedural meshes. It uses the system C++ compiler, to build a user-supplied snippet of C++ code, which needs to expose a generate function. The code is recompiled and the generate function is called automatically whenever the program detects that the source file has been modified externally. The current mesh is saved to a Wavefront OBJ file when pressing the W key. Any generated textures are saved as individual image files, and referenced in the exported OBJ material file.

Please note that this tool is meant as an aid for creating procedural geometry with my Mesh class and mesh generation utility functions (see mesh/ directory in http://github.com/jtsiomb/dropcode). It might seem awkward to require the use of a seemingly random collection of framework code in the generator functions rather than a purpose-designed mesh generation API, but that's by design for the intended purpose of this tool.

To learn how to use this tool, see the example mesh generator test.cc in the root directory, and consult the header files mesh.h and meshgen.h for the available mesh generation and manipulation functions.

All the vector/matrix math types and operations are provided by my current math library: http://github.com/jtsiomb/gph-math. So you need to install that first.

You will also need to install my multithreaded resource manager library: http://github.com/jtsiomb/libresman.
