From 8e49a3e028b9526d2ab7662a9f6683a72b6b6787 Mon Sep 17 00:00:00 2001 From: Samuel Iglesias Gonsalvez Date: Thu, 11 Dec 2014 23:34:13 +0100 Subject: [PATCH] main: fix return GL_FRAMEBUFFER_ATTACHMENT_TEXTURE_LEVEL value Return the proper value for two-dimensional array texture and three-dimensional textures. From OpenGL ES 3.0 spec, chapter 6.1.13 "Framebuffer Object Queries", page 234: "If pname is FRAMEBUFFER_ATTACHMENT_TEXTURE_LAYER and the texture object named FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is a layer of a three-dimensional texture or a two-dimensional array texture, then params will contain the number of the texture layer which contains the attached im- age. Otherwise params will contain the value zero." Furthermore, FRAMEBUFFER_ATTACHMENT_TEXTURE_LAYER is an alias of FRAMEBUFFER_ATTACHMENT_TEXTURE_3D_ZOFFSET_EXT.
