From 0e8a5a84742adf6e99236f246c77325fad174204 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 1 Jun 2009 14:59:11 -0600 Subject: [PATCH] st/mesa: fix incorrect sprite origin when drawing to FBO/texture Need to take the draw buffer's up/down orientation into consideration when setting the sprite_coord_mode field. Fixes inverted sprites when drawing into an FBO. --- src/mesa/state_tracker/st_atom_rasterizer.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/mesa/state_tracker/st_atom_rasterizer.c b/src/mesa/state_tracker/st_atom_rasterizer.c index 4e70510c0c0..5c7206409cf 100644 --- a/src/mesa/state_tracker/st_atom_rasterizer.c +++ b/src/mesa/state_tracker/st_atom_rasterizer.c @@ -192,7 +192,8 @@ static void update_raster_state( struct st_context *st ) raster->point_sprite = ctx->Point.PointSprite; for (i = 0; i < MAX_TEXTURE_COORD_UNITS; i++) { if (ctx->Point.CoordReplace[i]) { - if (ctx->Point.SpriteOrigin == GL_UPPER_LEFT) + if ((ctx->Point.SpriteOrigin == GL_UPPER_LEFT) ^ + (st_fb_orientation(ctx->DrawBuffer) == Y_0_BOTTOM)) raster->sprite_coord_mode[i] = PIPE_SPRITE_COORD_UPPER_LEFT; else raster->sprite_coord_mode[i] = PIPE_SPRITE_COORD_LOWER_LEFT; -- 2.30.2
