// dear imgui: Renderer Backend for OpenGL2 (legacy OpenGL, fixed pipeline)
|
|
// ImDrawIdx: vertex index. [Compile-time configurable type]
|
|
// - To use 16-bit indices + allow large meshes: backend need to set 'io.BackendFlags |= ImGuiBackendFlags_RendererHasVtxOffset' and handle ImDrawCmd::VtxOffset (recommended).
|
|
// - To use 32-bit indices: override with '#define ImDrawIdx unsigned int' in your imconfig.h file.
|
|
#ifndef ImDrawIdx
|
|
typedef unsigned short ImDrawIdx; // Default: 16-bit (for maximum compatibility with renderer backends)
|
|
#endif // #ifndef ImDrawIdx
|
|
// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
|
|
|
|
// Implemented features:
|
|
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture as texture identifier. Read the FAQ about ImTextureID/ImTextureRef!
|
|
// [X] Renderer: Texture updates support for dynamic font atlas (ImGuiBackendFlags_RendererHasTextures).
|
|
// [X] Renderer: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
|
|
// Missing features or Issues:
|
|
// [ ] Renderer: Large meshes support (64k+ vertices) even with 16-bit indices (ImGuiBackendFlags_RendererHasVtxOffset).

|
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
|
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

// **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.
