From f123981a96c8ab7d7cb3e77ecbcf0048cb3b79e6 Mon Sep 17 00:00:00 2001 From: reduz Date: Tue, 3 Nov 2020 16:51:53 -0300 Subject: [PATCH] Implement DirectionalLight2D Also separated Light2D in PointLight2D and DirectionalLight2D. Used PointLight2D because its more of a point, and it does not work the same as OmniLight (as shape depends on texture). Added a few utility methods to Rect2D I needed. --- core/math/rect2.h | 62 ++++ scene/2d/light_2d.cpp | 309 ++++++++++-------- scene/2d/light_2d.h | 101 ++++-- scene/register_scene_types.cpp | 5 +- servers/rendering/rasterizer.h | 13 +- .../rasterizer_rd/rasterizer_canvas_rd.cpp | 224 ++++++++++--- .../rasterizer_rd/rasterizer_canvas_rd.h | 14 +- .../rasterizer_rd/shaders/canvas.glsl | 224 ++++++++----- .../shaders/canvas_uniforms_inc.glsl | 5 +- servers/rendering/rendering_server_canvas.cpp | 83 +++-- servers/rendering/rendering_server_canvas.h | 12 +- servers/rendering/rendering_server_raster.h | 8 +- .../rendering/rendering_server_viewport.cpp | 126 ++++++- servers/rendering/rendering_server_wrap_mt.h | 8 +- servers/rendering_server.cpp | 9 +- servers/rendering_server.h | 30 +- 16 files changed, 869 insertions(+), 364 deletions(-) diff --git a/core/math/rect2.h b/core/math/rect2.h index 7660db71ebc..4e6cecaab2f 100644 --- a/core/math/rect2.h +++ b/core/math/rect2.h @@ -244,6 +244,68 @@ struct Rect2 { return Rect2(Point2(position.x + MIN(size.x, 0), position.y + MIN(size.y, 0)), size.abs());
