// dear imgui: Renderer for OpenGL3 / OpenGL ES2 / OpenGL ES3 (modern OpenGL with shaders / programmatic pipeline) // This needs to be used along with a Platform Binding (e.g. GLFW, SDL, Win32, custom..) // (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..) // Implemented features: // [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID in imgui.cpp. // You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this. // If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp. // https://github.com/ocornut/imgui // CHANGELOG // (minor and older changes stripped away, please see git history for details) // 2018-08-29: OpenGL: Added support for more OpenGL loaders: glew and glad, with comments indicative that any loader can be used. // 2018-08-09: OpenGL: Default to OpenGL ES 3 on iOS and Android. GLSL version default to "#version 300 ES". // 2018-07-30: OpenGL: Support for GLSL 300 ES and 410 core. Fixes for Emscripten compilation. // 2018-07-10: OpenGL: Support for more GLSL versions (based on the GLSL version string). Added error output when shaders fail to compile/link. // 2018-06-08: Misc: Extracted imgui_impl_opengl3.cpp/.h away from the old combined GLFW/SDL+OpenGL3 examples. // 2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle. // 2018-05-25: OpenGL: Removed unnecessary backup/restore of GL_ELEMENT_ARRAY_BUFFER_BINDING since this is part of the VAO state. // 2018-05-14: OpenGL: Making the call to glBindSampler() optional so 3.2 context won't fail if the function is a NULL pointer. // 2018-03-06: OpenGL: Added const char* glsl_version parameter to ImGui_ImplOpenGL3_Init() so user can override the GLSL version e.g. "#version 150". // 2018-02-23: OpenGL: Create the VAO in the render function so the setup can more easily be used with multiple shared GL context. // 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplSdlGL3_RenderDrawData() in the .h file so you can call it yourself. // 2018-01-07: OpenGL: Changed GLSL shader version from 330 to 150. // 2017-09-01: OpenGL: Save and restore current bound sampler. Save and restore current polygon mode. // 2017-05-01: OpenGL: Fixed save and restore of current blend func state. // 2017-05-01: OpenGL: Fixed save and restore of current GL_ACTIVE_TEXTURE. // 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle. // 2016-07-29: OpenGL: Explicitly setting GL_UNPACK_ROW_LENGTH to reduce issues because SDL changes it.
