devil

问题 I'm trying to load a bitmap into an OpenGL texture and display it to the screen, but when I do so, the red and blue values seem to switch (e.g.: a blue image appears orange, green images remain unchanged, etc..). This problem only exists when loading bitmaps, I can load .pngs relatively error free. This is the code I'm using to load the bitmaps and set the textures. I'm using DevIl, but I'm not sure how relevant that is, as the problem existed when I used a different system (I don't quite

问题 Firstly, I am using Fedora and learning OpenGL. I would like to work with DevIL a little, so I installed both DevIL and DevIL-ILUT packages from the official repository. I have a test code for loading and rendering a file available, so I decided to test it (I will be learning some DevIL basics at my course, and we were given that file to make sure DevIL works fine for us). The file contains line: #include "IL/devil_cpp_wrapper.hpp" so I copied the IL directory (which we also have available)

问题 I am on mingw (gcc version 4.5.2). I get a segfault when opening certain files, including PNGs and BMPs. It was working fine on a 128x128 PNG but when I started testing with larger files I started getting a segfault. There are no issues with the TGA format, though. I know the library works for the most part, but not knowing whether it will decide to crash and burn like this is not good. gdb does not give me any hints about what's going on. I am able to compile DevIL from source, and I

问题 I guess this is a two part problem, which is why I couldn't find a more suitable title for the post. I am loading an image using DevIL and then converting it to a familiar format. Here is the part of my code I am having troubles with: //Copy to OpenGL texture if(!ilConvertImage(IL_RGBA, IL_UNSIGNED_BYTE)) { throw runtime_error(std::string("Unable to convert image") +filename +std::string(" to display friendly format")); } glGenTextures(1, &Main::texture); glBindTexture(GL_TEXTURE_2D, Main:

问题 I just tried to use devIL and ULIT to help me with opengl texture loading. However, whenever the program starts, I get the error: "The application was unable to start correctly (0xc000007b). Click OK to close the application." What happened? I'm using the Visual C++ 2010 RC, windows 7 64-bit. 回答1: It may happen if you attempt to run a 64-bit application, but Windows finds only the 32-bit version of some dependent DLL. You can fix this by making sure all the 64-bit dependency DLLs can be found

问题 I'm trying to run the code located here: http://r3dux.org/2010/11/single-call-opengl-texture-loader-in-devil/ And it requires me to use DevIL, so I installed it to my c:\usr\ folder using the Win32 installer. I'm positive my environment is setup to read from the proper \lib folder as well. My linker looks like this: -lglfw -gluw32 -lopengl32 -lglu32 -ldevil Everything else loads fine, but when it gets to "ldevil", the compiler (Dev-C++) throws the error: File format not recognized. 回答1: Most

问题 I would like to create devIL image from raw texture data, but I can't seem to find a way to do it. The proper way seems to be ilLoadL with IL_RAW, but I can't get it to work. The documentation in here says that that there should be 13-byte header in the data, so i just put meaningless data there. If I put 0 to "size" parameter of ilLoadL, I'll get black texture, no matter what. Otherwise my program refuses to draw anything. ilIsImage returns true, and I can create openGL texture from it just

问题 actually i create a CMake script to localize the DevIL library using MSYS/MinGW on win32 platform. I've extend the origin FindDevIL CMake script to regard the MinGW root when try to find DevIL: project (DevILTest) cmake_minimum_required(VERSION 2.6) FIND_PACKAGE(OpenGL) IF(OPENGL_FOUND) MESSAGE(STATUS "OpenGL render API found.") MESSAGE(STATUS "Detected OpenGL path is : ${OPENGL_LIBRARIES}") ENDIF(OPENGL_FOUND) #Determine DevIL specific header file FIND_PATH(IL_INCLUDE_DIR il.h PATH_SUFFIXES
