It is up to you to decide what you want the void* to carry! + Dear ImGui knows nothing about what those bits represent, it just passes them around. It is up to you to decide what you want the void* to carry! It could be an identifier to your OpenGL texture (cast GLuint to void*), a pointer to your custom engine material (cast MyMaterial* to void*), etc. At the end of the chain, your renderer takes this void* to cast it back into whatever it needs to select a current texture to render. Refer to examples applications, where each renderer (in a imgui_impl_xxxx.cpp file) is treating ImTextureID as a different thing. (c++ tip: OpenGL uses integers to identify textures.
