// dear imgui: Renderer Backend for SDL_Renderer for SDL2
|
||
|
|
// (Requires: SDL 2.0.17+)
|
||
|
|
|
||
|
|
// Note how SDL_Renderer is an _optional_ component of SDL2.
|
||
|
|
// For a multi-platform app consider using e.g. SDL+DirectX on Windows and SDL+OpenGL on Linux/OSX.
|
||
|
|
// If your application will want to render any non trivial amount of graphics other than UI,
|
||
|
|
// please be aware that SDL_Renderer currently offers a limited graphic API to the end-user and
|
||
|
|
// it might be difficult to step out of those boundaries.
|
||
|
|
|
||
|
|
// Implemented features:
|
||
|
|
// [X] Renderer: User texture binding. Use 'SDL_Texture*' as ImTextureID. Read the FAQ about ImTextureID!
|
||
|
|
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
|
||
|
|
|
||
|
|
// 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.
