// ImGui Renderer for: OpenGL3 (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
|
|
|
|
// About OpenGL function loaders:
|
|
// Modern OpenGL requires individual functions to be loaded manually. Helper libraries are often used for this purpose.
|
|
// Here we are using gl3w.h, which requires a call to gl3wInit().
|
|
// You may use another any other loader/header of your choice, such as glew, glext, glad, glLoadGen, etc.
|
|
|
|
// About GLSL version:
|
|
// The 'glsl_version' initialization parameter defaults to "#version 130" if NULL.
|
|
// Only override if your GL version doesn't handle this GLSL version (see table at the top of imgui_impl_opengl3.cpp). Keep NULL if unsure!
