A class which defines a reversible transformation from one coordinate system to another by maintaining an inverse transformation matrix.
<p>
This version is similar to <a class="el" href="classcsTransform.html" title="A class which defines a transformation from one coordinate system to another.">csTransform</a> (in fact, it is a sub-class) but it is more efficient if you plan to do inverse transformations often. <dl class="remark" compact><dt><b>Remarks:</b></dt><dd>Despite that the superclass <a class="el" href="classcsTransform.html" title="A class which defines a transformation from one coordinate system to another.">csTransform</a> transforms from 'other' to 'this' space, commonly <a class="el" href="classcsReversibleTransform.html" title="A class which defines a reversible transformation from one coordinate system to another...">csReversibleTransform</a> instances are named like 'this2other' - e.g. 'object2world' where 'this' space is object space and 'other' space is world space. </dd></dl>
