Tesseract Trainer generates a full screen, real time display of a rotating tesseract, the analogue of the cube in 4 dimensions. It also adds point textures, which give you a feel of what each of the eight faces are doing. There's a stereoscopic option which adds 3D depth to the projection from 4D. It also features music and numerous other options to play with.
Haxial Calculator is a high precision mathematical assistant that evaluates normal (infix) expressions to practically any accuracy. Results can be viewed in normal, fraction, or scientific forms, and it allows you to work in any radix. Worksheets enable you to solve larger problems in a more suitable environment, as well as allowing you to save your work. It also incorporates unit and radix conversion utilities and complete support for variables. Haxial Calculator employs a user interface that allows you to freely type expressions with the keyboard instead of mimicking the button presses of a hand-held calculator.
EQUINOX-3D is a 3D modeler with a very fast, fully integrated ray-tracer. It features read/write support for COLLADA, read support for Radiance's .hdr image format, 3DS (3D-studio) file format read support, multi-texturing, custom-programmable texture mapping, bump-mapping with automatic texture-space tangents, the ability to zoom into a region with "fly-to", and more. It includes a full runtime-class framework and a core design that allows for the addition of anything from a physics engine to a fully integrated renderer from a plugin. It is faster and more memory efficient than many other modelers.
CADSM is a basic 3D CAD with advanced motion simulation capabilities. It is suitable for anyone interested in learning 3D CAD and motion simulation inexpensively before using more sophisticated packages. Educators, students, and new engineers will find it ideal for the teaching and learning of geometry, kinematics, dynamics, vibrations, mechanisms, linkages, cams, machine design, and physics. Data can be exported to spreadsheets or the POVRay ray tracer.
JFormula is a Java library for evaluating mathematical expression. It supports the +, -, *, ^, and % operators, boolean expressions, a short expression format (2x+3y), and variables. The evaluation tree is produced by a pluggable parsing system, and evaluation optimization for symbol value changes is provided. It includes a standard library with 17 mathematical functions, can delegate unknown functions or symbols, and can extend or add new libraries dynamically. Many API samples are included. It is multithreaded and JDK 1.1 compliant.
Hardware Debugger is a graphical tool for detecting, diagnosing, and testing custom hardware. It is designed to meet the needs of the hardware developer by enabling quick and easy testing of hardware without writing any code. Hardware Debugger runs under Linux, Solaris, and Windows.
