wire

wire is a niche 3d modeling and rendering library written in Go.

Dependencies

Direct dependencies are two other Go libraries I've been working on for some years:

• https://github.com/bit101/bitlib
• https://github.com/bit101/blcairo (requires https://cairographics.org/ C library).

Concept

wire models are made of 3d points and, optionally, segments, which connect two points.

A wire model can be rendered as 3d paths (wires) formed by stroking all the segments, or as a 3d point cloud by rendering all of the points. Or both.

Constraints

So many constraints!

• No triangles/polygons/filled surfaces,solid objects
• No z-sorting
• No normals
• No shaders
• No backface culling

Due to some of these constraints, monochromatic images and animations tend to work best. A secondary constraint.

That said, these constraints make space for a good amount of creativity in multiple styles.

Features

• A decent set of 3d primitives:
  • Sphere
  • Circle
  • Cylinder
  • Cone
  • Box
  • Pyramid
  • Torus
  • Torus knot
  • GridPlane
  • Spring
  • Text
• Where it makes sense, most of these can be rendered as:
  • Wireframe, with configurable longitudinal and latitudinal sections
  • Random points on the surface
  • Random points filling the object
• Objects can be:
  • Transformed: rotated, translated, scaled, or manually manipulated with custom functions
  • Cloned
  • Combined
  • Point-culled with custom functions
  • Subdivided
  • Randomized
  • Noisified (Simplex noise)
