// dear imgui: Renderer Backend for SDL_Renderer
|
||
|
|
// (Requires: SDL 2.0.17+)
|
||
|
|
|
||
|
|
// Important to understand: SDL_Renderer is an _optional_ component of SDL.
|
||
|
|
// 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 offers a limited graphic API to the end-user and it might
|
||
|
|
// be difficult to step out of those boundaries.
|
||
|
|
// However, we understand it is a convenient choice to get an app started easily.
|
||
|
|
|
||
|
|
// Implemented features:
|
||
|
|
// [X] Renderer: User texture binding. Use 'SDL_Texture*' as ImTextureID. Read the FAQ about ImTextureID!
|
||
|
|
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
|
||
|
|
// Missing features:
|
||
|
|
// [ ] Renderer: Multi-viewport support (multiple windows).
