// 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.

// About OpenGL function loaders:
|
|
// About OpenGL function loaders: modern OpenGL doesn't have a standard header file and requires individual function pointers to be loaded manually.
|
|
// 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.
