\|
*	Force-update shadows when the world is changed (#12364)	x2048	2022-05-26
\|
*	Quantize light frustum calculations (#12357)	x2048	2022-05-23
\| \| \| \| \| \| \|	* Quantize light frustum calculations Reduces shadow flicker * Fix function name to match conventions
*	Improve shadow filters (#12195)	x2048	2022-05-21
\| \| \| \| \| \| \| \| \|	* 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
*	Deal with compiler warnings	sfan5	2022-04-30
\|
*	Implement shadow offsets for the new SM distortion function (#12191)	x2048	2022-04-14
\| \| \| \| \| \| \| \|	* 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
*	Adjust shadowmap distortion to use entire SM texture (#12166)	x2048	2022-04-07
\|
*	Increase the ratio between shadow range and viewing range	Dmitry Kostenko	2022-04-02
\|
*	Limit shadow map to the viewing range (#12158)	x2048	2022-03-31
\|
*	Tune shadow perspective distortion (#12146)	x2048	2022-03-31
\| \| \| \| \|	* 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
*	Add API to control shadow intensity from the game/mod (#11944)	x2048	2022-03-26
\| \| \|	* Also Disable shadows when sun/moon is hidden. Fixes #11972.
*	Correct normal bias for entities	Dmitry Kostenko	2022-03-07
\| \| \| \| \| \|	Remove use of magic constants. Apply cameraOffset Calculate distance projected on SM plane
*	Reduce shadow jitter (#11668)	lhofhansl	2021-10-05
\|
*	Move updating shadows outside of RenderingCore::drawAll. (#11491)	x2048	2021-08-12
\| \| \| \|	Fixes indirect rendering modes such as some 3D modes mentioned in #11437 and undersampled rendering. Does not fully fix anaglyph 3d mode.
*	Distribute shadow map update over multiple frames to reduce stutter (#11422)	x2048	2021-07-25
\| \| \| \| \| \| \| \| \| \|	Reduces stutter and freezes when playing. * Maintains double SM and SM Color textures * Light frustum update triggers incremental generation of shadow map into secondary 'future' textures. * Every incremental update renders a portion of the shadow draw list (split equally). * After defined number of frames (currently, 4), 'future' and 'current' textures are swapped, and DirectionalLight 'commits' the new frustum to use when rendering shadows on screen.

*	Improve shadow rendering with non-default camera FOV (#11385)	x2048	2021-07-11
\| \| \| \| \| \| \| \| \| \| \|	* Adjust minimum filter radius for perspective * Expand shadow frustum when camera FOV changes, reuse FOV distance adjustment from numeric.cpp * Read shadow_soft_radius setting as float * Use adaptive filter radius to accomodate for PSM distortion * Adjust filter radius for texture resolution
*	Shadow mapping render pass (#11244)	Liso	2021-06-06
