// ImGui iOS+OpenGL+Synergy binding
|
||||
// In this binding, ImTextureID is used to store an OpenGL 'GLuint' texture identifier. Read the FAQ about ImTextureID in imgui.cpp.
|
||||
// Providing a standalone iOS application with Synergy integration makes this sample more verbose than others. It also hasn't been tested as much.
|
||||
// Refer to other examples to get an easier understanding of how to integrate ImGui into your existing application.
