From 84ae0fe3a5f5707a5ff658292fefcfc5f9cf04b8 Mon Sep 17 00:00:00 2001 From: Ray Molenkamp Date: Thu, 21 Jun 2018 18:35:37 -0600 Subject: GLRefactor: Refactor bf_blenfont to use GPUTexture instead of raw GL calls and types. In an effort to centralize all opengl calls in the codebase, this patch replaces the raw opengl calls in bf_blenfont with GPUTexture so it's no longer depended on opengl headers. reviewer: Brecht Differential Revision: https://developer.blender.org/D3483 --- source/blender/blenfont/intern/blf_glyph.c | 55 +++++++++++------------------- 1 file changed, 19 insertions(+), 36 deletions(-) (limited to 'source/blender/blenfont/intern/blf_glyph.c') diff --git a/source/blender/blenfont/intern/blf_glyph.c b/source/blender/blenfont/intern/blf_glyph.c index 5a87c726566..02d166739ec 100644 --- a/source/blender/blenfont/intern/blf_glyph.c +++ b/source/blender/blenfont/intern/blf_glyph.c @@ -57,6 +57,7 @@ #ifndef BLF_STANDALONE # include "GPU_immediate.h" +# include "GPU_extensions.h" #endif #include "blf_internal_types.h" @@ -146,7 +147,7 @@ GlyphCacheBLF *blf_glyph_cache_new(FontBLF *font) memset(gc->glyph_ascii_table, 0, sizeof(gc->glyph_ascii_table));
