- They mention “polar”, but ganja nor the code generator define
polar. The definition
aIis useful, but then again
Iis only mentioned up top where it says “I=PSS” - what is PSS? I have no idea.
Simply, “polar” is
1e012 in 2DPGA, but this is hard to grasp from the cheatsheet.
- What are those “hats” for, such as in the formula for distance between points P1 and P2?
They don’t seem to have any significance that I know of.They signify normalization (I figured it out through ganja). The cheatsheet should not use any symbols it has not defined previously (besides an agreed set of widely known operations, like inner product and outer product, and for those there should be a separate cheatsheet.
- Translator is given for “orthogonal to ideal point”. It would be more useful and understandable, if “direction” was used as the name instead of “ideal point”, and if the formula for translation “along” the direction, not orthongal to it, would be given.
