From 2efaa748e8bd8f4678dd15380794ae69c84c7c53 Mon Sep 17 00:00:00 2001 From: Thorbjørn Lindeijer Date: Sun, 22 Jul 2012 21:24:31 +0200 Subject: Added support for ARB_texture_non_power_of_two extension If the graphics driver supports this, there is no need to create textures with power-of-two dimensions. It is then also preferred to use regular textures than relying on the older GL_ARB_texture_rectangle extension. --- src/resources/image.cpp | 3 ++- src/resources/image.h | 1 + 2 files changed, 3 insertions(+), 1 deletion(-) (limited to 'src/resources') diff --git a/src/resources/image.cpp b/src/resources/image.cpp index 9a3e2ba2..3afa479f 100644 --- a/src/resources/image.cpp +++ b/src/resources/image.cpp @@ -36,6 +36,7 @@ #ifdef USE_OPENGL bool Image::mUseOpenGL = false; +bool Image::mPowerOfTwoTextures = true; int Image::mTextureType = 0; int Image::mTextureSize = 0; #endif @@ -544,7 +545,7 @@ void Image::setLoadAsOpenGL(bool useOpenGL) int Image::powerOfTwo(int input) { int value; - if (mTextureType == GL_TEXTURE_2D) + if (mPowerOfTwoTextures) { value = 1; while (value < input && value < mTextureSize) diff --git a/src/resources/image.h b/src/resources/image.h index 7df74c3f..33db7848 100644 --- a/src/resources/image.h +++ b/src/resources/image.h @@ -249,6 +249,7 @@ class Image : public Resource int mTexWidth, mTexHeight; static bool mUseOpenGL; + static bool mPowerOfTwoTextures; static int mTextureType; static int mTextureSize; #endif -- cgit v1.2.3-70-g09d2
