// dear imgui: Renderer for OpenGL2 (legacy OpenGL, fixed pipeline) |
|
// 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! |
|
|
|
// 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 |
|
|
|
// **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)** |
|
// **Prefer using the code in imgui_impl_opengl3.cpp** |
|
// This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter to read. |
|
// If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything more |
|
// complicated, will require your code to reset every single OpenGL attributes to their initial state, and might |
|
// confuse your GPU driver. |
|
// The GL2 code is unable to reset attributes or even call e.g. "glUseProgram(0)" because they don't exist in that API. |
