From 7f86da6c609191dbad1887fe5683dfee087fa909 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Tue, 15 Sep 2009 17:08:33 -0600 Subject: [PATCH] progs/demos: create a texture object in lodbias.c Before, we were using the default texture object (name=0). This caused the intel_generate_mipmap() path to fail since passing texture=0 to glFramebufferTexture2DEXT() causes us to _unbind_ the texture if present. --- progs/demos/lodbias.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/progs/demos/lodbias.c b/progs/demos/lodbias.c index 30b1ed13d5f..8d39bd605a7 100644 --- a/progs/demos/lodbias.c +++ b/progs/demos/lodbias.c @@ -43,6 +43,7 @@ static GLboolean Anim = GL_TRUE; static GLint Bias = 0, BiasStepSign = +1; /* ints avoid fp precision problem */ static GLint BiasMin = -400, BiasMax = 400; static int win = 0; +static GLuint TexObj = 0; static void @@ -214,6 +215,9 @@ static void Init( void ) glPixelStorei(GL_UNPACK_ALIGNMENT, 1); + glGenTextures(1, &TexObj); + glBindTexture(GL_TEXTURE_2D, TexObj); + if (glutExtensionSupported("GL_SGIS_generate_mipmap")) { /* test auto mipmap generation */ GLint width, height, i; -- 2.30.2
