// dear imgui: Renderer for modern OpenGL with shaders / programmatic pipeline
|
||||
// - Desktop GL: 2.x 3.x 4.x
|
||||
// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
|
||||
// This needs to be used along with a Platform Binding (e.g. GLFW, SDL, Win32, custom..)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bit indices.
|
||||
|
||||
// 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)
|
||||
// 2020-01-07: OpenGL: Added support for glbindings OpenGL loader.
|
||||
// 2019-10-25: OpenGL: Using a combination of GL define and runtime GL version to decide whether to use glDrawElementsBaseVertex(). Fix building with pre-3.2 GL loaders.
|
||||
// 2019-09-22: OpenGL: Detect default GL loader using __has_include compiler facility.
|
||||
// 2019-09-16: OpenGL: Tweak initialization code to allow application calling ImGui_ImplOpenGL3_CreateFontsTexture() before the first NewFrame() call.
|
||||
// 2019-05-29: OpenGL: Desktop GL only: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-03-29: OpenGL: Not calling glBindBuffer more than necessary in the render loop.
|
||||
// 2019-03-15: OpenGL: Added a dummy GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized GL function loaders early.
|
||||
// 2019-03-03: OpenGL: Fix support for ES 2.0 (WebGL 1.0).
|
||||
// 2019-02-20: OpenGL: Fix for OSX not supporting OpenGL 4.5, we don't try to read GL_CLIP_ORIGIN even if defined by the headers/loader.
|
||||
// 2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
|
||||
// 2019-02-01: OpenGL: Using GLSL 410 shaders for any version over 410 (e.g. 430, 450).
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-11-13: OpenGL: Support for GL 4.5's glClipControl(GL_UPPER_LEFT) / GL_CLIP_ORIGIN.
|
||||
// 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. (#752)

// dear imgui: Renderer for modern OpenGL with shaders / programmatic pipeline
|
||||
// - Desktop GL: 2.x 3.x 4.x
|
||||
// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
|
||||
// This needs to be used along with a Platform Binding (e.g. GLFW, SDL, Win32, custom..)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bit indices.
|
||||
|
||||
// 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
|
||||
|
||||
// About Desktop OpenGL function loaders:
|
||||
// Modern desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.
|
||||
// Helper libraries are often used for this purpose! Here we are supporting a few common ones (gl3w, glew, glad).
|
||||
// You may use another loader/header of your choice (glext, glLoadGen, etc.), or chose to manually implement your own.
|
||||
|
||||
// About GLSL version:
|
||||
// The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
|
||||
// On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
|
||||
// Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.
