The design changes coming with pynodes for the node editor allow editing multiple node groups or pinning. This is great for working on different node groups without switching between them all the time, but it causes a problem for viewer nodes: these nodes all write to the same Image data by design, causing access conflicts and in some cases memory corruption. This was not a problem before pynodes because the editor would only allow 1 edited node group at any time. With the new flexibility of node editors this restriction is gone.
In order to avoid concurrent write access to the viewer image buffer and resolve the ambiguity this patch adds an "active viewer key" to the scene->nodetree (added in bNodeTree instead of Scene due to otherwise circular DNA includes). This key identifies a specific node tree/group instance, which enables the compositor to selectively enable only 1 viewer node.
The active viewer key is switched when opening/closing node groups (push/pop on the snode->treepath stack) or when selecting a viewer node. This way only the "last edited" viewer will be active.
Eventually it would be nicer if each viewer had its own buffer per node space so one could actually compare viewers without switching. But that is a major redesign of viewer nodes and images, not a quick fix for bcon4 ...
The previous fix limited overlap, but is sometimes
too conservative, and artists want way to turn off
the limiting, so added 'Allow Overlap' option to
modifier.
Casting a ray onto an editmesh was building a derivedMesh, raytree, then freeing for every ray-cast.
Noticed while using ruler+snapping in editmode.
Instead of attempting to align the MFace and edit-mesh tessfaces, just use editmesh for ray-casting.
Reverted the trunk revision 56136 and part of revision 56127 concerning the local Main
for Freestyle and temporary scene generation for stroke rendering.
The function do_merge_fullsample() in pipeline.c has access to the Scene of each Render,
so that the temporary Scene generated by Freestyle has to be kept for FSAA even after
stroke rendering has been done. By the same token, the local Main has been moved from
the BlenderStrokeRenderer class to Render. It is noted that free_all_freestyle_renders()
in pipeline.c is intended to get the temporary Scene of each Render released specifically
taking account of the FSAA case.
- disabling ruler snap wasn't setting the points depth back to its previous value before snapping.
- adding a new ruler uses the depth of the previous active ruler (fallback to view center as before)
- deleting the ruler now sets the prev/next ruler active.
- enable site-packages for bundled python distrobution, py3.2 had a problem where it would try to parse headers we didnt include, but its resolved now.
- workaround for glitch I was having on arch-linux where lib64 would be be used for the bundled python directory when it was just a symlink.
Changing actions via RNA (or apparently from the Action Editor browse menu too)
didn't perform all the necessary updates/tagging/recalc needed to have the
results of the new action get immediately applied in the 3D view. This caused
problems for exporters, as the first frames exported would be incorrect (though
this could probably be worked around by manually stepping the current frame
forward one frame then back again).
Allow separate control for tex/mask/cursor overlay. This commit implements
separate overlays for mask textures and cursor curves. The user can turn on
and off separate parts of the overlay by using the appropriate widgets.
The cursor overlay widgets are located at the tool selection panel
Also fixed alpha masks not getting correctly masked and mask texture mapping
not having the correct update callback
properties were continuously redrawing, which slowed down everything else.
The problem was integer overflow, with a short only capable of storing values
up to 32767. Note that sockets are collapsed by default since the previous
release, and that's it's not very useful to edit such complex node setups in
the properties editor, it's mainly meant for simple setups or group nodes to
present just a few sockets.
Two main things:
- Made a python operator for selection in a viewport
which will de-select everything if nothing is under
the mouse.
To do so needed to modify VIEW3D_OT_select, so invoke
sets mouse location which is later used by exec
function.
This way it's possible to select stuff from python
defined operator.
Not best-ever solution since ideally exec() shall not
do OpenGL stuff, but we've got this issue in some
other operators. We'll solve this later.
- Used a keymap from Gianmichele Mariani as a reference,
updated his keymap to latest changes in operators.
We shall match Maya keymap much better now, thanks
for the keymap dude!
