Could someone explain what the "double-precision patches" does in the display options? The TBC Help description "Select this check box to specify that double-precision patches be used for surfaces." is not much help.
"Patches" are an object type that we use internally to represent surfaces. Using "Double precision" uses a 64 bit number to store and manipulate the verticies of the object. This is needed for very large sizes and or extremely small precision. Single precision uses 32 bit numbers which require 1/2 the memory with the loss of some precision.
Either should work fine for almost all projects. This setting allows us to fine tune the program for special cases. Stick with default setting of not being checked unless directed otherwise is my recommendation.
