// dear imgui: Renderer for DirectX9
|
||||
// This needs to be used along with a Platform Binding (e.g. Win32)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'LPDIRECT3DTEXTURE9' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
|
||||
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bits indices.
|
||||
|
||||
// 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.

// (minor and older changes stripped away, please see git history for details)
|

// 2019-05-29: DirectX9: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX9: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-03-29: Misc: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects().
|
||||
// 2019-01-16: Misc: Disabled fog before drawing UI's. Fixes issue #2288.
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx9.cpp/.h away from the old combined DX9+Win32 example.
|
||||
// 2018-06-08: DirectX9: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-05-07: Render: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud.
