1 // ImGui Renderer for: OpenGL3 (modern OpenGL with shaders / programmatic pipeline) 2 // This needs to be used along with a Platform Binding (e.g. GLFW, SDL, Win32, custom..) 3 // (Note: We are using GL3W as a helper library to access OpenGL functions since there is no standard header to access modern OpenGL functions easily. Alternatives are GLEW, Glad, etc..) 4 5 // Implemented features: 6 // [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID in imgui.cpp. 7 8 // You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this. 9 // If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp. 10 // https://github.com/ocornut/imgui 11 12 // About GLSL version: 13 // The 'glsl_version' initialization parameter defaults to "#version 130" if NULL. 14 // Only override if your GL version doesn't handle this GLSL version (see table at the top of imgui_impl_opengl3.cpp).
