// 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] User texture binding. Use 'GLUint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
|
|
// [X] Multi-viewport rendering (when ImGuiConfigFlags_ViewportsEnable is enabled).
|
|
|
|
// **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.
