Also they did not work when using blender -R from
command line in 64-bit systems.
Issue was checking for wrong define which would
cause code to detect if the blender executable
functions under 32 bit emulation.
For 64bit executables this is false, leading
blender to believe we are operating under a 32bit
system, and registration would try to register
the 32bit thumbnailer.
This 32 bit dll is (correctly) missing for local
installs and from the new installer, thus no thumbnails.

Own stupid error in recent fix for buffer overflow in `BLI_testextensie_glob()`...
Also found & fixed another potential buffer overflow in this func.

Unmeasurable speedup for plane intersection.
|
|
Unlike the 3 plane method, the 2 planes squared cross-product _is_ the determinant.
|
|
tris with ~1e-05 edge lengths would fail
|
|
|
|
|
|
Passing zero epsilon allowed divide by zero.
|
|
We had too many warnings lately... was awaiting that someone would kill them - didn't happen -> goes to my commit ratio! :P
|
|
Logic was ok, but would run into precision issues.

Project both triangles onto the same plane to simplify calculations.
|
|
epsilon check here didn't account for scale, causing T45919
|
|
- closest_to_plane3 (for float3 planes)
- closest_to_plane*_normalized_v3 (for unit length planes)
Use when the plane is known to be unit length

* Fix BLI_file_touch, used to add one dummy byte ((unsigned char)EOF) to empty files!
* Get rid of static global temp string in WIN32 area (very bad, and useless!).
* Get rid of paranoid NULL checks in WIN32's BLI_gzopen().
* Add non-relative filename asserts to WIN32 file operations too.
* ifdef-out BLI_move and BLI_create_symlink, unused (and the later is not even implemented for windows).
Partly based on patch and points raised by Jason Wilkins (jwilkins) in T32870, thanks!

BLI_str_quoted_substrN could crash if the prefix wasn't found

dist_squared_to_line_v2, dist_to_line_v2

Also remove 2x vector normalize since other parts of the code already check this.
Fixes T45849
|
|
By default watertight intersections are used,
For callbacks where its not needed,
BLI_bvhtree_ray_cast_ex can be called without the BVH_RAYCAST_WATERTIGHT flag.
Fixes T45286

From Cycles with some very minor differences.
|

|
|
This was already the case for most users of ray-cast.
Doing this avoids 2x normalize calls per ray-cast in many places.
|
|
|
|
The mystery here is, how MSVC could not break on such error? :(
|
|
The callback checks if 2 nodes intersect (not just their AABB).
Advantages:
- theres no need to allocate overlaps which are later ignored.
- expensive intersection tests will run multi-threaded.
Currently only used for Python API.
|
|
This is known to be <32, so no need to malloc every item.
|
|
|
|
Also define epsilon var for ray-cast functions.

It basically rewrites most of filelist.c, with some more limited changes in other areas of filebrowser.
From user perspective, it:
* Removes some info in 'long' drawing mode (owner, permissions) - OS-specific data that do not really matter in Blender!
* Makes short/long display 'fixed' size (among four choices, like thumbnails mode).
* Allows to list several layers of dirtree at once, in a flat way (inside .blend files and/or real directories).
* Consequently, adds datablocks types filtering.
* Uses way less RAM when listing big directories, especially in thumbnail mode (we are talking of several hundred of MiB spared).
* Generates thumbnails way faster.
From code perspective, it:
* Is ready for asset engine needs (on data structure level in filebrowser's listing).
* Simplifies and makes 'generic' file listing much lighter.
* Separates file listing in three different aspects:
** 'generic' filelisting (in BLI), which becomes a shallow wrapper around stat struct.
** 'filebrowser drawing' filelisting, which only contains current visible subset of the whole list (sliding window), with extra drawing data (strings for size, date/time, preview, etc.).
** 'asset-ready' filelisting, which is used for operations common to 'basic' filehandling and future asset-related one.
* Uses uuid's to handle file selection/state in the browser, instead of using flags in filelisting items.
* Uses much lighter BLI_task handling for previews, instead of heavy 'job' system (using the new 'notifier' timer to handle UI refresh, in similar way to jobs).
* Moves .blend datablocks preview handling to IMB_thumbnail (necessary to avoid storing all datablock previews at once, and gives better consistency and performances too).

Thanks to Campbell & Sergey for the reviews. :)

For popup interactions we need to know if events are in the region or not,
however subtracting the shadow isn't so reliable, since its not always added to all sides of a popup.
Instead, get the winrct value from a popup using the block rect, otherwise the winrct as-is.
|
|
Also, factorized internal code to get global mutex from its ID.
