scaffoldsContext: See this variable in context in the source code References: This variable is used as follows: * ScaleObject uses objectScaffold
This table contains an object's scaffold, in a format that supports quick and easy scaling (see the ScaleObject routine). Each object has its own scaffold, which contains all the measurements that we need to build that object. The object is constructed using only measurements from the scaffold, so if we want to scale the object, we can just scale the scaffold. Each object has a number of entries in this table, one for each scaffold measurement, in decreasing order of size (so the largest measurements come first). Each scaffold measurement is in one of these binary formats: %00000ccc %1abbbccc where a = %a, b = %bbb and c = %ccc. The value represented by %00000ccc is: 1 --------- 2^(c - 2) and the value represented by %1abbbccc is: a 1 1 - + --------- + --------- 2 2^(b - 2) 2^(c - 2) In both cases, the result is a multiple of 1/32, so each of these entries represents a fraction of the form n/32. The ScaleObject routine takes the scaffold for a specific object and scales it by multiplying each scaffold measurement by the following: scaleUp ----------- 2^scaleDown The resulting values are stored in the scaledScaffold table, which uses the same structure as the object's section in the objectScaffold table, but contains the scaled scaffold to use when drawing the scaled object.
