From f4411b58ade1d4d0921243756ecd3499e8d11cd2 Mon Sep 17 00:00:00 2001 From: Pablo Dobarro Date: Thu, 6 Feb 2020 22:14:18 +0100 Subject: Fix T72721: Add visibility flags updates to the PBVH Currently, there its a function that sets manually the fully_hidden flag of the nodes from the visibility operators in paint_hide.c. The undo code was not updating the flag, so the visibility state of the nodes was incorrect after preforming undo operations. This sometimes was drawing fully hidden nodes with empty buffers, causing artifacts in the geometry. I added a function to mark nodes which visibility state changed (similar as we are updating the mask flags and the nodes bounding boxes). This way, the tools, operators and undo code don't have to update the visibility flags, making everything much simpler to understand and maintain. I did not remove the flag update code from the current visibility operators in this patch, but after reimplementing them (and all the new ones) in the new visibility system, all visibility updates should be done using this method and the BKE_pbvh_node_fully_hidden_set function should be removed.
