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

Adjust shadowmap distortion to use entire SM texture (#12166)

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

Apply texture matrix when rendering shadowmap

Fixes shadows of animated sprite entities

Apply shadow only to the naturally lit part of the fragment color (#11722)

2021-10-31T18:18:30+00:00

Fragment color for nodes is now calculated from: * Texture color, highlighted by artificial light if present (light color conveyed via vertex color). * Texture color highlighted by natural light (conveyed via vertex color) filtered by shadow. * Reflected day/moonlight filtered by shadow (color and intensity), assuming some portion of the light is directly reflected from the materials.

Improvements to colored shadows (#11516)
