Improve shadow filters (#12195)

2022-05-21T14:49:30+00:00

* 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

Implement shadow offsets for the new SM distortion function (#12191)

2022-04-14T20:49:30+00:00

* 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

Tune shadow perspective distortion (#12146)

2022-03-31T20:40:06+00:00

* 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)

* Also Disable shadows when sun/moon is hidden. Fixes #11972.
