SpriteBatch and BasicEffect for C++ Direct3D 11

Originally posted to Shawn Hargreaves Blog on MSDN, Friday, March 2, 2012

Over the Christmas break I spent some time porting the built-in XNA effects (BasicEffect, SkinnedEffect, etc.) to native C++ using Direct3D 11.  Finding that strangely enjoyable, I went on to make a C++ version of SpriteBatch, and also ported the XNA Primitives 3D sample, built-in state objects, and helper vertex types.  And my colleague Chuck Walbourn chimed in with some code for easily loading Direct3D 11 textures.

Supported operating systems:

• Windows 8 Consumer Preview (both Metro and Desktop)
• Windows 7
• Windows Vista with DirectX 11 update

Supported compilers:

• Visual Studio 11 (currently in beta)
• Visual Studio 2010 plus the standalone Windows 8.0 SDK  (you need the SDK to get the latest version of DirectXMath, which this code depends on)

How to use it:

• Unzip, load the solution into Visual Studio, and build it
• Link your program with the resulting static lib
• Add the Inc  folder to your include path

To draw sprites:

    #include "SpriteBatch.h"

    using namespace DirectX;

    std::unique_ptr<SpriteBatch> spriteBatch(new SpriteBatch(deviceContext));

    spriteBatch->Begin();
    spriteBatch->Draw(texture, XMFLOAT2(x, y));
    spriteBatch->End();

To draw geometry using BasicEffect:

    #include "BasicEffect.h"

    using namespace DirectX;

    std::unique_ptr<BasicEffect> effect(new BasicEffect(device));

    effect->SetWorld(world);
    effect->SetView(view);
    effect->SetProjection(projection);

    effect->SetTexture(cat);
    effect->SetTextureEnabled(true);

    effect->EnableDefaultLighting();

    effect->Apply(deviceContext);

    deviceContext->IASetInputLayout(...);
    deviceContext->IASetVertexBuffers(...);
    deviceContext->IASetIndexBuffer(...);
    deviceContext->IASetPrimitiveTopology(...);

    deviceContext->DrawIndexed(...);

To draw geometric primitives:

    #include "GeometricPrimitive.h"

    using namespace DirectX;

    std::unique_ptr<GeometricPrimitive> teapot(GeometricPrimitive::CreateTeapot(deviceContext));

    teapot->Draw(world, view, projection, Colors::CornflowerBlue);

See the readme inside the zip for more info.
