Two example files that crashed texture nodes.
- On delete texture nodes, it should free the exec cache (because this cache
stores the node pointer.
- On redo, nodes can exist can exist without typeinfo set. Exec (free) code
was not checking for that. Don't ask me why this happens... tex nodes are weird.
Main purpose of this is to be more compatible with older
versions of blender (before alpha cleanup) where sequencer
used to display premultiplied image on an straight opengl
viewport.
Now sequencer preview would behave closer to image editor
However adding Alpha and R|G|B displays is not so simple
because sequencer is using 2D textures. Would be nice to
implement this options as well, but this is not so much
important IMO.
This hall fix
- #34453: VSE: Subtract function does not work properly
TODO: Make RGBA display default for our startup.blend
- linking groups into a scene now uses the objects original layers (some users have the layers set to useful values, so overwriting isnt so nice).
- dropping objects into the 3d view would make them active but not selected, a valid but confusing state, since most tools activate and select now objects.
This fixes the placement code of new files added to the sequencer timeline.
The old code tried to guess the strip position from the current mouse
pointer position.
Annoying effect: if you add a new strip using the menu, especially if the
file editor pops up, the strip ends up in nowheres land (most likely around
track 40, frame -200).
New behaviour: strips are always placed at cfra, which is the
sequencer equivalent to the 3D cursor (and that's where new objects in
3D editing end up).
Bonus feature: we try our best to guess the right track by finding the
nearest strip by type.
The patch was inspired by
[#32766] VSE: Add Strip on Current Frame
Thanks to venomgfx for the idea!
Also made it theraded linear solver, seems it makes
sense for iterative schur with inner iterations
enabled.
Use OpenMO's max therads called from bundler code
to detect how many threads to use. Could be changed
in a way that number of threads is passing in options
from blender side in the future.
Also removed redundant V3D definition from compiler's
flags.
This commits adds extra refirenment entry in the menu which is
"K1, K2" and which will apparently refine only this distortion
coefficients.
This would be useful in cases when you know for sure focal length
(which could be obtained from lens, EXIF and so) but not sure
about how good you manual calibration is.
Be careful tho, there're no internal constraints on this
coefficients so distortion model could just screw up into insane
values.
Would not expect any significant changes in solver behavior, but
it could be more accurate in some cases.
Switching projective intersection to ceres is marked as a TODO
for now.
in fact the keymap editor was missing other keymaps so added these too,
also updated keymap checker to make sure there is no mismatch with region/space types.
code is still unused, but the intention is to use this to solve the double sided
lighting problem on NVidia, and to make the materials work on OpenGL ES 2.0
eventually.
The code works and matches the fixed function lighting pretty much exactly, but
still needs optimizations. The actual integration in object draw will be
committed later when more fixing & testing, there's lots of different combinations
and unclear OpenGL state here.
With new bundle adjustment based on Ceres we don't need
SSBA library anymore. This also means we don't need ldl
library and libmv is no longer depends on colamd as well.
Patch originally written by me, then finished by Sergey. Big
thanks to Sergey for troopering through and fixing the many issues
with my original (not compilable) patch.
The Ceres implementation uses 2 parameter blocks for each camera
(1 for rotation and 1 for translation), 1 parameter block for
common intrinsics (focal length etc) and 1 parameter block for
each track (e.g. bundle or 3D point).
We turn on some fancy optimizer options to get better performance,
in particular:
options.preconditioner_type = ceres::SCHUR_JACOBI;
options.linear_solver_type = ceres::ITERATIVE_SCHUR;
options.use_inner_iterations = true;
options.use_nonmonotonic_steps = true;
options.max_num_iterations = 100;
Special thanks to Sameer Agarwal of Ceres fame for splitting out
the SCHUR_JACOBI preconditioner so that it didn't depend on
CHOLMOD. Previously we could not use that preconditioner in
Blender because CHOLMOD is too large of a dependency for Blender.
BundleIntrinsicsLogMessage:
- Moved bunch of if(foo) LG << "bar" into this function, to make
EuclideanBundleCommonIntrinsics a little bit easier to follow.
EuclideanBundle:
- Fix RMSE logging.
While it's not a good idea to create convex hull shapes from objects
with no volume, this makes them behave a little nicer.
