Example of TIR: PRISMIRR.LEN - A Prism/Mirror System
Prismirr is the final system from the prism data-entry example. It can be used to check your results. This system is the final result of the right-angle prism example . It shows the use of total internal reflection surfaces, the ben command, and hatched reflectors. For the solid-model drawing...
Wheel mouse not functioning properly in the Surface Data Spreadsheet
Question I notice that if I use my IntelliPoint wheel mouse to roll up and down on any of the spreadsheets in OSLO, it works in only one direction. After I hit the bottom of the spreadsheet, the mouse wheel works for rolling up only. If I have too many element groups in the surface data...

CCL and pointers.
Question Why doesn't CCL have pointers? Synopsis CCL and pointers. Solution They are not needed. The main reasons for pointers in C concern the structure of arrays, and passing function parameters by reference. CCL uses conventions similar to Fortran for these functions, allowing hidden structs on...
