* Rewrite shadow filtering for the new distortion
* Calculate penumbra radius using a single sample
* Avoid peter-panning effect due to filtering of short shadows
* Add adaptive filter quality for soft shadows
* Avoid sharp shadows on surfaces without normals (e.g. plants)
* Increase default and maximum soft shadow radius
* Make line numbers in shader errors match the code
The logging streams now do almost no work when there is no output target for them.
For example, if LL_VERBOSE has no output targets, then `verbosestream << x` will return a StreamProxy with a null target. Any further `<<` operations applied to it will do nothing.
This commit introduces mt_localtime() in src/gettime.h, a wrapper
around the OS-specific thread-safe versions of localtime()
(resp. localtime_s on Windows and localtime_r in other systems).
Per the Open Group recommendation,
«portable applications should call tzset() explicitly before using
ctime_r() or localtime_r() because setting timezone information is
optional for those functions», so we also do a one-shot
call of tzset() (_tzset() on Windows to avoid warning C4996).
The function is used to replace the localtime() calls in
getTimestamp() and makeScreenshot().
(The only reminaing call to localtime() in the tree now is the one in
the local copy of the Lua source code.)
As reported in #12197, b0b9732359
introduces a regression in worldalign textures.
The specific change that seems to be responsible for this issue is the
change in order between the computation of the cuboid texture
coordinates and the box edge correction.
Fix#12197 by moving the box edge correction back to before the cuboid
texture coordinates, as it used to be.
Stop scaling images to POT immediately when loaded. The 'combine'
modifier hardcodes X and Y coordinates, and so behaves incorrectly
if applied to a scaled image. Images emitted by generateImage()
are already scaled to POT before being used as a texture, so
nothing should break.
* Move shadow position calculation to vertex shaders
* Animate entire scene before rendering shadows to prevent lagging of shadows
* Remove unnecessary use of PolygonOffsetFactor
* Apply normal offset to both nodes and objects
* Rename getPerspectiveFactor -> applyPerspectiveDistortion
* Remove perspective distortion from fragment shaders
* Pass perspective distortion parameters as uniforms
* Set all perspective bias parameters via ShadowRenderer
* Recalibrate perspective distortion and shadow range to render less shadow geometry with the same quality and observed shadow distance
* Allow to set the displayed item count and its offset via meta
* fix rect constr call
* devtest: add dump_item chatcommand
* fix rect2 constr call (sdim is a position (typedef for v2s32), not a dimension) and remove background because it would work now
* add missing utf8 to wide conversion
* rename to count_meta
