Core Geometry Version 12 extends and improves its already strong capabilities in geometric computing. A unified representation of geometric regions and new user-assistance capabilities enhance usability and simplify workflows. New functions allow users to easily model, analyze and synthesize geometric regions. Unified representation and automatic visualization of regions. » Attached cells for meshes with direct actions. Built-in fractal regions including Cantor meshes and space-filling curves. » Automatic region construction from 2D or 3D images. » Support for computing perimeter and surface area for regions. New spatial relations for testing region equality, inclusion and overlap. New planar and higher-dimensional angle computation. » New path constructor formed by a sequence of translations and 3D rotations. » Efficient generation of points uniformly on a unit sphere. » Improved discretization of parametric regions and graphics primitives. Improved support for Boolean operations. Enhanced region measure computations. Extended support for linear cells in mesh region framework.
