Jitter Geometry

The jit.geom family of objects, like jit.geom.shape, are a specialized group of Jitter objects designed to work with Half-edge Geometry Structures. These make certain transformations and operations much easier and more efficient.

• Generating shapes - Use jit.geom.shape to create simple geometries with an arbitrary number of subdivisions.
• Vertex adjustment - The jit.geom.remesh object lets you rearrange the vertices of a geometry, making them more evenly distributed without changing the overall shape. You can add and remove vertices with jit.geom.subdivide and jit.geom.decimate.
• Transformations - Smooth out a geometry with jit.geom.smooth, add roughness or procedural displacement with jit.geom.dimples and jit.geom.displace, or perform more radical transformations with jit.geom.twist, jit.geom.waves, and jit.geom.xform.
• Property generation - Create dynamic, adjustable shapes with lifelike surface properties, using jit.geom.texgen and jit.geom.normgen to generate texture coordinates and surface normals.
