Cassandra is a scientific data viewer based on VTK. Cassandra provides dynamic interaction with the VTK pipeline and enables the user to load plug-ins dynamically in order to perform specific tasks in data manipulation and visualisation. Cassandra is open and modular, and can easily be extended to new filters through a set of dynamically loadable plug-ins. A plug-in template is provided to help users to develop and share their own plug-ins. This approach allows users to perform complex filtering without any specific knowledge of VTK or C++.
Kelvin is a units converter intended for scientists, teachers, and students who need a reliable tool for fast conversion. Some categories included are: acceleration, area, frequency, atomic physics, density, electrical capacitance, electromagnetic radiation, energy/work, flow, force, fuel consumption, illumination, length, luminance, luminous flux, magnetomotive force, mass, power, prefixes and suffixes, pressure and stress, specific heat, speed/velocity, temperature, thermal resistance, time, torque, viscosity (dynamic), viscosity (kinematic), volume, and dry/liquid capacity.
