Changing diagram angles
I want to make my pieces more vibrant and beautiful. I know there is a way to mathematically change facet angles based on R.I. However, I am at a complete loss as to how to do this.
Say, for example, I have a diagram for quartz with a RI of around 1.5. My C1 angles are 49.6. I want to cut a beryl with a RI of around 1.6. How do I change that 49.6 specific to quartz to something more appropriate for the RI of the beryl to maximize light refraction?
I would like to be able to create an Excel file to easily change my refractive indices for me. Is there a formula that works every time?
Thanks all!
