jOcular

jOcular is a software application that enables users to design a fully functional optical system. It provides numerous elements that can be lined up to simulate photon trajectories.

The program does not have any special hardware requirements, but it needs Java Runtime Environment to run properly. The interface is clean and well organized in several menus. However, the application is not multi-tabbed, meaning users can work on only one project at a time.

From the main window of jOcular, users can add various elements by right-clicking and selecting them from there. There are a great number of individual items that mimic real materials, allowing users to generate accurate results. Unfortunately, users cannot create objects of their own; the application works only with the templates provided by the developer.

Users can design an optical system and observe the way in which light refracts, reflects or transmits through various materials. This application can be used to simulate how a live system would work. The entire optical system can be previewed in a 3D visualization based on the parameters set by the users.

The application has a number of limitations, among which the lack of drag and drop. Users cannot move elements in the preview window. JOcular provides only three preset viewing options for the light projections, while the 3D visualization of the system can easily be rotated and spun.

jOcular is capable of generating simulated images, meaning users can preview an 'Imager' display of their light projection. Results can be previewed in a separate window, allowing users to modify parameters and make live modifications.

To summarize, jOcular is an interesting piece of software with complex mechanics that are not meant for beginners. It is a specialized application that enables users to build optical systems and test various scenarios. There are some missing features, but since it is free to use, it may prove appealing to users.
