From d6b3a193d4d525c5048ebf793e6a63fd98f92d64 Mon Sep 17 00:00:00 2001 From: Zack Rusin Date: Wed, 31 Jul 2013 07:34:49 -0400 Subject: draw: inject frontface info into wireframe outputs Draw module can decompose primitives into wireframe models, which is a fancy word for 'lines', unfortunately that decomposition means that we weren't able to preserve the original front-face info which could be derived from the original primitives (lines don't have a 'face'). To fix it allow draw module to inject a fake face semantic into outputs from which the backends can figure out the original frontfacing info of the primitives.
