// dear imgui: Renderer for DirectX10 // This needs to be used along with a Platform Binding (e.g. Win32) // Implemented features: // [X] Renderer: User texture binding. Use 'ID3D10ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp. // 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. // https://github.com/ocornut/imgui // CHANGELOG // (minor and older changes stripped away, please see git history for details) // 2018-07-13: DirectX10: Fixed unreleased resources in Init and Shutdown functions. // 2018-06-08: Misc: Extracted imgui_impl_dx10.cpp/.h away from the old combined DX10+Win32 example. // 2018-06-08: DirectX10: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle. // 2018-04-09: Misc: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) on other back-ends. // 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX10_RenderDrawData() in the .h file so you can call it yourself. // 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves. // 2016-05-07: DirectX10: Disabling depth-write. #include "imgui.h" #include "imgui_impl_dx10.h" // DirectX #include #include #include #include // DirectX data static ID3D10Device* g_pd3dDevice = NULL; static IDXGIFactory* g_pFactory = NULL; static ID3D10Buffer* g_pVB = NULL; static ID3D10Buffer* g_pIB = NULL; static ID3D10Blob* g_pVertexShaderBlob = NULL; static ID3D10VertexShader* g_pVertexShader = NULL; static ID3D10InputLayout* g_pInputLayout = NULL; static ID3D10Buffer* g_pVertexConstantBuffer = NULL; static ID3D10Blob* g_pPixelShaderBlob = NULL; static ID3D10PixelShader* g_pPixelShader = NULL; static ID3D10SamplerState* g_pFontSampler = NULL; static ID3D10ShaderResourceView*g_pFontTextureView = NULL; static ID3D10RasterizerState* g_pRasterizerState = NULL; static ID3D10BlendState* g_pBlendState = NULL; static ID3D10DepthStencilState* g_pDepthStencilState = NULL; static int g_VertexBufferSize = 5000, g_IndexBufferSize = 10000; struct VERTEX_CONSTANT_BUFFER { float mvp[4][4]; }; // Render function // (this used to be set in io.RenderDrawListsFn and called by ImGui::Render(), but you can now call this directly from your main loop) void ImGui_ImplDX10_RenderDrawData(ImDrawData* draw_data) { ID3D10Device* ctx = g_pd3dDevice; // Create and grow vertex/index buffers if needed if (!g_pVB || g_VertexBufferSize < draw_data->TotalVtxCount) { if (g_pVB) { g_pVB->Release(); g_pVB = NULL; } g_VertexBufferSize = draw_data->TotalVtxCount + 5000; D3D10_BUFFER_DESC desc; memset(&desc, 0, sizeof(D3D10_BUFFER_DESC)); desc.Usage = D3D10_USAGE_DYNAMIC; desc.ByteWidth = g_VertexBufferSize * sizeof(ImDrawVert); desc.BindFlags = D3D10_BIND_VERTEX_BUFFER; desc.CPUAccessFlags = D3D10_CPU_ACCESS_WRITE; desc.MiscFlags = 0; if (ctx->CreateBuffer(&desc, NULL, &g_pVB) < 0) return; } if (!g_pIB || g_IndexBufferSize < draw_data->TotalIdxCount) { if (g_pIB) { g_pIB->Release(); g_pIB = NULL; } g_IndexBufferSize = draw_data->TotalIdxCount + 10000; D3D10_BUFFER_DESC desc; memset(&desc, 0, sizeof(D3D10_BUFFER_DESC)); desc.Usage = D3D10_USAGE_DYNAMIC; desc.ByteWidth = g_IndexBufferSize * sizeof(ImDrawIdx); desc.BindFlags = D3D10_BIND_INDEX_BUFFER; desc.CPUAccessFlags = D3D10_CPU_ACCESS_WRITE; if (ctx->CreateBuffer(&desc, NULL, &g_pIB) < 0) return; } // Copy and convert all vertices into a single contiguous buffer ImDrawVert* vtx_dst = NULL; ImDrawIdx* idx_dst = NULL; g_pVB->Map(D3D10_MAP_WRITE_DISCARD, 0, (void**)&vtx_dst); g_pIB->Map(D3D10_MAP_WRITE_DISCARD, 0, (void**)&idx_dst); for (int n = 0; n < draw_data->CmdListsCount; n++) { const ImDrawList* cmd_list = draw_data->CmdLists[n]; memcpy(vtx_dst, cmd_list->VtxBuffer.Data, cmd_list->VtxBuffer.Size * sizeof(ImDrawVert)); memcpy(idx_dst, cmd_list->IdxBuffer.Data, cmd_list->IdxBuffer.Size * sizeof(ImDrawIdx)); vtx_dst += cmd_list->VtxBuffer.Size; idx_dst += cmd_list->IdxBuffer.Size; } g_pVB->Unmap(); g_pIB->Unmap(); // Setup orthographic projection matrix into our constant buffer // Our visible imgui space lies from draw_data->DisplayPos (top left) to draw_data->DisplayPos+data_data->DisplaySize (bottom right). { void* mapped_resource; if (g_pVertexConstantBuffer->Map(D3D10_MAP_WRITE_DISCARD, 0, &mapped_resource) != S_OK) return; VERTEX_CONSTANT_BUFFER* constant_buffer = (VERTEX_CONSTANT_BUFFER*)mapped_resource; float L = draw_data->DisplayPos.x; float R = draw_data->DisplayPos.x + draw_data->DisplaySize.x; float T = draw_data->DisplayPos.y; float B = draw_data->DisplayPos.y + draw_data->DisplaySize.y; float mvp[4][4] = { { 2.0f/(R-L), 0.0f, 0.0f, 0.0f }, { 0.0f, 2.0f/(T-B), 0.0f, 0.0f }, { 0.0f, 0.0f, 0.5f, 0.0f }, { (R+L)/(L-R), (T+B)/(B-T), 0.5f, 1.0f }, }; memcpy(&constant_buffer->mvp, mvp, sizeof(mvp)); g_pVertexConstantBuffer->Unmap(); } // Backup DX state that will be modified to restore it afterwards (unfortunately this is very ugly looking and verbose.
