also minor optimization for BM_edge_in_face(), check edges radial loops rather then the faces edges
since normally there are 0-2 faces attached to an edge compared to 3+ edges in a face.
- add support for using the active point's orientation.
- add support for creating new custom orientations from curves.
- fix error where only the last selected curve handle was taken into account for manipulator orientations.
existing code was very stupid.
- all ID pointers for clipboard strips are handled uniformly.
- clipboard stores a duplicate ID pointer which are restored on paste.
- restoring pointers...
-- use ID's that are still in the database (copy&paste within the same file).
-- fallback to name lookup.
-- fallback to loading them from the original filepath (movie-clip and sound only).
also fix bug pasting where initialing the sound wasn't done if there was no frame-offset.
this means in editmode with wire draw, face and vertex normals don't have to be calculated at all.
in most cases the normals are not used so add a flag that makes calculating them only for functions that need them.
also fix face normal calculation for CDDM, was using quad calculation for ngons too.
- when an fcurve had no selected keyframes, a default fallback value was used which caused view-selected to include frame 1, even when no selected frames were there.
- the vertical axis was always reset, ideally we would center vertically too but the way this operator currently works we only know about the frame range,
now don't change the vertical scroll when viewing selected since it would always jump to the top of the screen (view-all still acts this way).
This was in fact really nasty bug, caused by multitex_nodes
function using global variable R (which is a copy of current
renderer). this variable is not initialized to anything
meaningful for until first rendering (preview or final)
happened.
Since multitex_nodes might be used outside of render pipeline,
made it so whether CM is on or off as an argument to functions
multitex_ext_safe and multitex_ext. Now multitex_nodes() is
only shall be used for stuff happening from render pipeline!
Also needed to make some changes to other places, so all the
usages of texture sampling knows for the fact whether CM is
on or off.
And one more change is related on behavior of dispalcement,
wave, warp, weightvg modifiers and smoke. They'll be always
using CM off since texture is used for influence, not for
color.
It's rather bigger patch, but it's mostly straightforward
changes, which we really need to be done.
Reviewed by Brecht, thanks!
- BLI_strncpy_wchar_from_utf8 wasn't NULL terminating the destination string, caused uninitialized memory use in BPY_python_start().
- BLI_strncpy_wchar_as_utf8 could write one byte past the buffer bounds.
With deformations and on a simple cube you could get axis flipping with normal-particle alignment.
now use the normal & tangent to create the orientation to give a stable matrix that wont flip.
