Printing text on the color grid image would initialize font glyphs from a thread at
the same time as the UI, causing conflicts. The freetype glyph renderer needs to be
mutex locked because it uses a shared buffer internally even when rendering for
different fonts. Also needed to change the image generate function to use the render
monospace font to avoid conflicts in blenfont.
What's still weak in the blenfont API is that there is no distinction between a font
and a thread using that font to render with some particular size, style, etc.
in some cases. The dupli code would still do object updates during render indirectly,
while this is disabled for thread safety everywhere else, now we disable it for this
case as well.
Not a pretty solution but this is for the depgraph refactor to solve.
rendering. This used to happen in an unneeded frame change update which was
removed. For heavy particle systems this could have a bad impact on viewport
performance after rendering.
of the active object in the 3D view. This was due to sharing a global G.moving
flag to indicate that transform is active, now it's only set per transform data
type so different editors don't influence each other.
node materials.
Area and region listener callbacks now get the screen and area pointers passed, so
they can do more fine grained checks to see if redraw is really needed, for example
depending on the 3D view drawtype.
Also construct orco uv layer when converting curve to a mesh.
This makes it possible to preserve automatically generated coordinates
("use uv for mapping" option) when using constructive modifiers or
converting curve to the mesh.
With cycles nothing special is needed to preserve texture mapping
after such operations, in blender internal you'll need to change
texture mapping from Generated to UV.
This feature is useful on it's own and also would help in potential
switch 3d viewport to always use DM to draw objects, which would
help making drawing more thread-safe.
Issue was caused by svn rev57566 which didn't take into
account the fact that curves could have dm of type CCGDM
and in this case CDDM_calc_normals_mapping_ex would fail
dramatically.
Added a check around normals update call bout whether
DM is CDDM or not. The same happens in mesh's modifier
stack.
* First step towards a new vector transform node, to convert Points/Vectors between World/Object/Camera space.
This only contains the Blender UI, RNA... code, no Cycles integration yet.
caused by recent changes in normal calculation, however curves were not being very smart about calculating modifiers (calling unneeded re-tessellation for every modifier)
Moved all the static variables into a PROCESS
structure which is now passing all over to where
static variables used to be used.
There's still one static variable which is
cubetable, but it's being initialized once
and then used read-only. Maybe we'll need
to move cubetable initialization to blender
startup, but that could wait a bit for now.
For users it means BI rendered viewport
wouldn't crash when using metaballs.
