From e71d3ee394e2849c1716af27cc87f9b6167da8ad Mon Sep 17 00:00:00 2001 From: Campbell Barton Date: Thu, 16 Aug 2012 16:07:00 +0000 Subject: use filtersize of 1.0 for distort and uv - compositor nodes. Experimenting here and 0.765625f is too sharp, but 1.0 wont blur with 0 distorted pixels but gives nice interpolation otherwise. --- source/blender/compositor/intern/COM_MemoryBuffer.cpp | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'source/blender/compositor/intern/COM_MemoryBuffer.cpp') diff --git a/source/blender/compositor/intern/COM_MemoryBuffer.cpp b/source/blender/compositor/intern/COM_MemoryBuffer.cpp index ee1c0320f5f..0994f3f8890 100644 --- a/source/blender/compositor/intern/COM_MemoryBuffer.cpp +++ b/source/blender/compositor/intern/COM_MemoryBuffer.cpp @@ -283,7 +283,14 @@ void MemoryBuffer::readEWA(float result[4], float fx, float fy, float dx, float // Use a different radius based on interpolation switch, just enough to anti-alias when interpolation is off, // and slightly larger to make result a bit smoother than bilinear interpolation when interpolation is on // (minimum values: const float rmin = intpol ? 1.f : 0.5f;) + + /* note: 0.765625f is too sharp, 1.0 will not blur with an exact pixel sample + * useful to avoid blurring when there is no distortion */ +#if 0 const float rmin = ((sampler != COM_PS_NEAREST) ? 1.5625f : 0.765625f) / ff2; +#else + const float rmin = ((sampler != COM_PS_NEAREST) ? 1.5625f : 1.0f ) / ff2; +#endif imp2radangle(A, B, C, F, &a, &b, &th, &ecc); if ((b2 = b * b) < rmin) { if ((a2 = a * a) < rmin) { -- cgit v1.2.3
