From 36c071082a39878fd910cd235b0a6b58760f6694 Mon Sep 17 00:00:00 2001 From: reimar Date: Tue, 13 Jun 2006 19:55:20 +0000 Subject: Do not use border for bicubic filter helper texture, since it will cause ATI cards to switch to software mode and be unusable. Double texture size to avoid this causing artefacts. Note: yuv=6 will not be changed, so it will stay unusable with ATI cards unless ATI starts supporting this. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@18696 b3059339-0415-0410-9bf9-f77b7e298cf2 --- libvo/gl_common.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'libvo') diff --git a/libvo/gl_common.c b/libvo/gl_common.c index f0362c76f1..19d0fb9439 100644 --- a/libvo/gl_common.c +++ b/libvo/gl_common.c @@ -621,14 +621,14 @@ static void store_weights(float x, GLfloat *dst) { } //! to avoid artefacts this should be rather large -#define LOOKUP_BSPLINE_RES (1024) +#define LOOKUP_BSPLINE_RES (2 * 1024) /** * \brief creates the 1D lookup texture needed for fast higher-order filtering * \param unit texture unit to attach texture to */ static void gen_spline_lookup_tex(GLenum unit) { - GLfloat tex[4 * (LOOKUP_BSPLINE_RES + 2)]; - GLfloat *tp = &tex[4]; + GLfloat tex[4 * LOOKUP_BSPLINE_RES]; + GLfloat *tp = tex; int i; for (i = 0; i < LOOKUP_BSPLINE_RES; i++) { float x = (float)(i + 0.5) / LOOKUP_BSPLINE_RES; @@ -636,9 +636,9 @@ static void gen_spline_lookup_tex(GLenum unit) { tp += 4; } store_weights(0, tex); - store_weights(1, &tex[4 * (LOOKUP_BSPLINE_RES + 1)]); + store_weights(1, &tex[4 * (LOOKUP_BSPLINE_RES - 1)]); ActiveTexture(unit); - glTexImage1D(GL_TEXTURE_1D, 0, GL_RGBA16, LOOKUP_BSPLINE_RES + 2, 1, GL_RGBA, GL_FLOAT, tex); + glTexImage1D(GL_TEXTURE_1D, 0, GL_RGBA16, LOOKUP_BSPLINE_RES, 0, GL_RGBA, GL_FLOAT, tex); glTexParameterf(GL_TEXTURE_1D, GL_TEXTURE_PRIORITY, 1.0); glTexParameteri(GL_TEXTURE_1D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexParameteri(GL_TEXTURE_1D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); -- cgit v1.2.3
