>>26677 aw man. i lost this thread
well i have seen the lens theory and by assuming n1.sin@1 = n2.sin@2 , one can then assume than sin@2 is just n1/n2 * sin@1, thus the size of @2 is as big as @1 but with n1 defining the "forward" and n2 multiplying the "hypothenuse", since they are the same side of the ratio, i guess, so the bigger the n2, the longer the hypothenus, such and such
but this all is my assumption only, and honestly, while it is expensive for computer,
i am surprised it is not done manually first to affirm the guessing, unlike other things like reflections which are more general in drawing? very strange
expectantly i need a stronger assurance than that of a 3d software or photo, which also means youtube tutorials are only enough descriptive than completely
