|
Release 1.2.2
|
|
=============
|
|
|
|
**New Features**
|
|
|
|
- Introducing the EvalLimit API : the Eval module aims at providing support for
|
|
computational tasks that are not related to drawing the surfaces. The EvalLimit
|
|
sub-module provides an API that enables client code to evaluate primitive variables
|
|
on the limit surface.
