Example PixelCNC Projects
Here are some example demonstration projects to help users become acquainted with how to go about creating certain projects in PixelCNC.
8"x5" Slow and Steady.pnc - A simple relief carving style project that employs 3D contouring and 2.5D milling operations. The canvas composition comprises several elements that were traced into paths that were then used to generate some 3D forms using the 'Shapes From Paths' and 'Stroke Paths' functions.
6"x6" Skull Fractal Pattern.pnc - A relief carving with an interesting texture. This project uses the '2.5D Offset Milling' operation to rough out the workpiece. Re-roughing is done with a standard 'Parallel Carving' operation, bringing it closer to shape before finally coming in with a 'Tessellated Carving' operation for adding the patterned texture.
10"x12" Pirate V-Carve.pnc - An example of a more advanced V-carving that's produced from a single image. Parts of the design are too wide for a 1/2" V-bit to cut by itself. A '2D Offset Milling' operation removes inner-most material while cleanup of spots the endmill can't reach is done in multiple passes by a '2D Profile Milling' operation using the same 1/2" V-bit used for V-carving.
6"x6" Tree Of Life Relief.pnc - This project's 3D design has been created from a black-and-white source image using PixelCNC's canvas editing functionality. The circular design of the project is a great use case for the 'Spiral Carving' operation which is utilized for both roughing and finishing of the relief carving, using 1/4" and 3/32" ballnose cutters, respectively.
This is a command-line utility for converting TGA image files into triangle-optimized *.STL/Stereolithography heightmap meshes. Areas with less detail are represented using fewer triangles while more complicated areas are formed out of a higher number of triangles. This is to reduce the overall polycount of the resulting mesh to improve performance when loading the model file into a program for use.
This utility does have some limitations that may be inconvenient. PixelCNC's ability to export a mesh is a much improved version of the algorithm.
