Curves may not be not initialized when called from python. C code
explicilty says that curvemapping_initialize should be called prior to
evaluating the curve, however the curve clip rectangle is not available
when calling evaluation on the curvemap. This is not possible unless we
force the evaluation on CurveMapping level, not on CurveMap level.
For now just pass a rectangle with the x boundary values of the curvemap
for evaluation to avoid the crash.
This commit implement's OCIO's Looks idea which
is about applying some color correction on the
buffer before it get's affected by a display
transform.
This is mainly used to modify images in an
artistics way.
Currently we've got looks generated from film
response curves for all sorts of cameras.
Patch by both of me and Brecht.
- The "Same Object" chaining option enabled (see follow-up discussions in Bug #36629).
- Sphere radius set to 0.1 (was 1.0 resulting in a longer computation time).
- ability to change the space the axis is projected in (so you can choose worldspace or -space, was always local-space before).
- support projecting on a negative axis, without this some very simple clamping is not possible if the direction happened not to be positive.
- add distance limit (same as modifier), without this single meshes surrounding an object would make the constraint impossible to use in some cases (it would snap to the wrong side).
note: this removes the ability to project on multiple axes at once but this option only added up directions and didnt project on multiple axes as you might expect.
When tabs to spaces is enabled and a paste command is undone, the improper number of characters could get removed. Also fixed issue with shift + left/right only selecting a max of 1 character.
- add missing headers from cmake (own omission)
- quiet rna_test.c unused define warnings.
- minor style edits
- spelling corrections and ignore all uppercase words with spell checking script.
rotation of the brush mask texture.
Unfortunately secondary path does not work here because we do not have a
permanent switch to choose between primary-secondary brush texture. Use
operator property instead.
Track margin checks needed some tweaks to deal better with the fact
that normalized values for the same pixel values might be different
across X and Y axis.
Also, non-centered patters are expected to be handling better now.
So now, their generation is controlled by a flag, else previous "simple values" group ids are generated (one per poly region, no need here to reduce the number of used IDs!).
Will update obj exporter too.
In fact, smooth groups are supposed to be bitflags, not simply integer values (would be far too much simple!). This adds quite a bit of work, as with only 32 values, we can't just assign one to each group. Somewhat related to the "Four colors theorem"! ;)
Here we simply use the first available bit for current smooth group (i.e. first bit not used by any of the already defined contiguous groups).
The BKE_bpath_traverse_id method updates path variables of image data blocks, but did not cause the image to be reloaded (or rather, tagged so it gets reloaded on next use). This requires also updating
all the ImageUser "ok" tags, which happens in some odd places in other cases where reload happens (e.g. the reload operator and the image path button handler function in image template).
Byte images and movies will now fully follow input color space.
Before this non-sRGB input colorspace for byte images and movies
behave really doggy (results in preview and final render were
totally different).
To prevent data loss, if byte image is set not stored in sequencer's
space it'll be internally converted to float buffer.
In theory some setups might be rendering a bit different now, but
new behavior is totally expected and someone used non-sRGB input
space for byte images/movies had Convert Float enabled anyway.
Issue was caused by tacks map merge re-allocating the tracks and this
didn't update plane tracks.
Ideally tracks_map_merge shall not re-allocate tracks, but for now
just update plane tracks. Shouldn't be too much slow anyway and could
always be tweaked without affecting any artists.
curve children of a triangle vertex parent would only display their relationship line to the first vertex. (confusing)
also added OB_TYPE_SUPPORT_PARVERT macro.
previously this had to be done one by one.
both single and triagle vertex parents can be made, selected based on distance to the verts.
Developer notes:
- looks like this was old TODO, enums existed but weren't used.
- only meshes currently support using.
- added BKE_object_as_kdtree(), may come in handy for similar cases.
