While there's usually plenty of optimization potential left in scripting space, at the end of the article, you'll also find a few C++ patches for SG/FG adding features to the Canvas system for exposing additional functionality to each Canvas/element, i.e. to help disable Canvas entirely, to track update/rendering times per Element or to get comprehensive OSG stats for each active Canvas camera. | While there's usually plenty of optimization potential left in scripting space, at the end of the article, you'll also find a few C++ patches for SG/FG adding features to the Canvas system for exposing additional functionality to each Canvas/element, i.e. to help disable Canvas entirely, to track update/rendering times per Element or to get comprehensive OSG stats for each active Canvas camera. | ||

While these features are currently intended to be a just ''toolbox'' for better understanding Canvas internals, the hope in the mid-term is also that these can be used for determining future extensions/improvements to the Canvas system as a whole. | While these features are currently intended to be a just ''toolbox'' for better understanding Canvas internals, the hope in the mid-term is also that these can be used for determining future extensions/improvements to the Canvas system as a whole. | ||
