PotterDraw is a free 3D software application for designing and visualizing pottery. It’s useful for creating cylindrical shapes such as pots, flasks, vases, bowls, plates, cups, glasses, goblets, or anything similar. The outer wall of the pot is drawn using a spline, which consists of one or more curved or linear segments. The inner wall is generated automatically.

PotterDraw can export files suitable for 3D printing. It can also map synthesized or user-specified textures onto the pot. Mesh and texture properties can be modulated by oscillators for more complex effects, and the modulations can be animated to create videos.

The SourceForge Speed Test measures Latency/Ping, Jitter, Download Speed, Upload Speed, Buffer Bloat, and Packet Loss. Upon completion, you can view detailed reports about your connection. This HTML5 speed test does not require Flash or Java, and works on all devices including tablets and smartphones. Host on your own infrastructure or use ours. For licensing, inquire today.

  • draw outer wall with Bézier curves (cubic splines); inner wall is generated automatically
  • distort mesh with 3D effects: scallop, ripple, twist, bend, etc.
  • distort texture with parameterized functions: stripes, rings, petals, polar, etc.
  • mesh and texture properties can be modulated with oscillators and animated
  • add color by synthesizing a texture, or use your own image as texture
  • export 3D model as color PLY file, monochrome STL file, or Wavefront OBJ file
  • PLY export supports both texture mapping and vertex color
  • export 2D images as BMP or PNG files
  • record video as sequentially numbered images, convertible to video using ffmpeg or VLC
