Discregrid is a C++ library for the parallel discretization of (preferably smooth) functions on regular grids. It generates a (cubic) polynomial discretization given a box-shaped domain, a grid resolution, and a 3D scalar field. The library can also serialize and deserialize the generated discrete grid, and compute and discretize the signed distance field corresponding to a triangle mesh. The following programs are included with Discregrid:

• GenerateSDF: Computes a discrete (cubic) signed distance field from a triangle mesh in OBJ format.

• DiscreteFieldToBitmap: Generates an image in bitmap format of a two-dimensional slice of a previously computed discretization.

• GenerateDensityMap: Generates a density map from a previously generated discrete signed distance field using the cubic spline kernel.

OpenImageIO is a library for reading and writing images, and a bunch of related classes, utilities, and applications. There is a particular emphasis on formats and functionality used in professional, large-scale animation and visual effects work for film.

AzPainter is a lightweight full color painting application for editing illustrations and images.

Features include:

• Layers

• Many artistic filters

• Good range of selection tools

• Pen pressure support with automatic brush size adjustment

• Support for 16-bit color images with transparency (RGBA)

• Support for image formats like PSD, PNG, JPEG, TIFF, WebP

OpenVDB is a C++ library comprising a hierarchical data structure and a large suite of tools for the efficient storage and manipulation of sparse volumetric data discretized on three-dimensional grids. It was developed by DreamWorks Animation for use in volumetric applications typically encountered in feature film production.

Blender is a 3D graphics creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. The application can be customized via its API for Python scripting.

Alembic is a computer graphics interchange framework. It distills complex, animated scenes into a set of baked geometric results.

ASLI (A Simple Lattice Infiller) is a command-line tool that allows users to fill any 3D geometry with a functionally graded lattice. The lattice infill is constructed out of unit cells, described by implicit functions, whose type, size and feature can be varied locally to obtain the desired local properties.
