From 7955c63bd171d3f5dabdbe1e794d15701701d993 Mon Sep 17 00:00:00 2001 From: Jocelyn Turcotte Date: Wed, 26 Nov 2014 15:58:12 +0100 Subject: Fix the visualization of unmerged batch geometries without index indexData() is null for most QSGGeometryNodes subclasses in QtQuick, make sure that we draw using vertex array data in that case. The patch also increases the contrast of the line pattern, since it is almost invisible with brighter hue values, to make it easier to see which batches aren't merged.
