Add precision mode to radial operator by keeping the shift key pressed.
Precision mode works by checking difference between absolute window
coordinates and the point where shift was pressed and adding those to
the distance between that point and the radial center. This allows
bigger negative/positive range than using a strict radial scheme.
Missed some passes in the previous commit. Now seems all the passes
are covered, at least with my understanding of the things.
There're some weird things going around with the refraction pass,
but that is caused by some other issue in the code. Would rather
call it a TODO for now.
Make pie menu item placement touch the radius from the internal side of
the buttons rather than placing on the center on the cirtcle. This
allows us to get rid of the separate visual angle property, also allows
for tighter placement of pies with a smaller radius without easily
overlapping.
Also pie menu title now always appears above the threshold indicator.
Root of the issue goes back to the on-fly normals commit and the
latest fix for it wasn't actually correct. I've mixed two fixes
in there.
So the idea here goes back to storing negative scaled object flag
and flip runtime-calculated normal if this flag is set, which is
pretty much the same as the original fix for the issue from me.
The issue with motion blur wasn't caused by the rumtime normals
patch and it had issues before, because it already did runtime
normals calculation. Now made it so motion triangles takes the
negative scale flag into account.
This actually makes code more clean imo and avoids rather confusing
flipping code in mesh.cpp.
This is rather workaround solution for now, which seems to
work and it's not that huge to maintain (one liner apart from
the comment).
Idea is to make sure PeekMessage peeks the message when window
proc receives WM_MOUSEWHEEL (some touchpad drivers seems to
swallow the messages making it so PeekMessage doesn't get
anything).
This is just another issue caused by convertblender overwriting the object
matrix at the time of creating render object. What's even worse here is that
original matrix is not stored for the lamps, only lamp_matrix*view_matrix is
stored.
For sure we can combine lar->co and lar->mat back to mat4, multiply by the
inverse view matrix and get object matrix, but this is not suitable for the
viewport render because every viewport rotation will accumulate the error.
For now let's store worldspace lamp matrix in the LampRen structure and use
it when rotating the scene.
Attempt to make soften brush faster by allowing non-symmetric kernels.
Projective painting supports those naturally but for 2D painting there's
a small hack to avoid shifting of the texture. Not totally correct but
it works for now.
Sampling still samples the texture color in transparent areas. This is
not so bad but users may get confused when clicking on a white spot and
picking black instead of the mesh color.
Krita also has this uncertainty when picking in transparent areas but we
do not interpolate with an explicit "transparent" looking texture during
viewport drawing (maybe we should), so it's not so apparent what happens
here.
