From 71a20f7c981ed66e1ba2e4c90c258c7506a9fb6b Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Mon, 23 Feb 2015 22:41:13 +0100 Subject: vo_opengl: explicitly check potential candidates for polar filters This adds a small check for candidates that could potentially be inside the radius, but aren't necessarily. This speeds up performance by a negligible amount on my hardware, but it's mainly a prerequisite for a further change (using a larger true radius). --- video/out/gl_video_shaders.glsl | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'video/out/gl_video_shaders.glsl') diff --git a/video/out/gl_video_shaders.glsl b/video/out/gl_video_shaders.glsl index f8aef48b9b..b95953bfa6 100644 --- a/video/out/gl_video_shaders.glsl +++ b/video/out/gl_video_shaders.glsl @@ -312,6 +312,11 @@ float[6] weights6(sampler2D lookup, float f) { lo = min(lo, c); \ hi = max(hi, c); +#define SAMPLE_POLAR_POTENTIAL(LUT, R, X, Y) \ + if (length(vec2(X, Y) - fcoord)/R < 1.0) { \ + SAMPLE_POLAR_HELPER(LUT, R, X, Y) \ + } + #define SAMPLE_CONVOLUTION_POLAR_R(NAME, R, LUT, WEIGHTS_FN, ANTIRING) \ vec4 NAME(VIDEO_SAMPLER tex, vec2 texsize, vec2 texcoord) { \ vec2 pt = vec2(1.0) / texsize; \ -- cgit v1.2.3
