2022-08-10Node vertex shader: Properly use the waved world position (#12665)DS
2022-05-21Improve shadow filters (#12195)x2048
* 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
2022-04-14Implement shadow offsets for the new SM distortion function (#12191)x2048
* 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

2022-04-07Adjust shadowmap distortion to use entire SM texture (#12166)x2048
2022-03-31Tune shadow perspective distortion (#12146)x2048
* 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
2022-03-26Add API to control shadow intensity from the game/mod (#11944)x2048
* Also Disable shadows when sun/moon is hidden. Fixes #11972.

2022-01-02Fix shadow mapping when PCF is disabled (#11888)x2048
2021-10-31Apply shadow only to the naturally lit part of the fragment color (#11722)x2048
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.

2021-07-25Distribute shadow map update over multiple frames to reduce stutter (#11422)x2048
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.

2021-07-25Add smooth light-shadow transition at noon (#11430)x2048
Node faces with normals pointing East/West (+X/-X) will transition between light and shadow at noon. This code makes the transition smooth.
2021-07-11Improve shadow rendering with non-default camera FOV (#11385)x2048
* 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

2020-12-22Fix GLES shader support after #9247 (#10727)Vitaliy
2020-12-19Cleanup shader generation code (#10663)Vitaliy
Shader generation is a mess. This commit cleans some parts up, including dropping remains of HLSL support which was never actually implemented.
2020-12-04Fix MSAA stripes (#9247)HybridDog
This only works when shaders are enabled. The centroid varying avoids that the textures (which repeat themselves out of bounds) are sampled out of bounds in MSAA. If MSAA (called FSAA in minetest) is disabled, the centroid keyword does nothing.
