Rendering with Direct3D - Direct3D Rendering - page 56

Getting ready

We'll start by creating a new Windows Form Application project named
Ch02_01RenderingPrimitives in the D3DRendering.sln solution:

1. Add the SharpDX.dll , SharpDX.DXGI.dll and SharpDX.Direct3D11.dll

references like we did in the previous recipes.

2. Next, we will add a reference to .\External\bin\SharpDX.D3DCompiler.dll

for dealing with our shader code.

3. An important step before we get started is to ensure that we are copying the Direct3D

d3dcompiler_46.dll DLL to the build directory, as this will let us compile our
shaders at runtime. To do this, open the project properties, select Build Events,
and add the following code to the Post-build event command line:
copy "$(SolutionDir)\External\Bin\Redist\D3D\x86\d3d*.dll"
"$(TargetDir)"

If you are not entirely familiar with .NET 4.5 yet, the behavior of AnyCPU
has changed. Now there is an additional option Prefer 32-bit. For all new
.NET 4.5 projects, this is selected by default—this is why we are using the
32-bit version of d3dcompiler_46.dll .

4. Make sure that you have the Common rendering framework project (that we used in

the Using the sample rendering framework recipe earlier in this chapter) added to
your D3DRendering.sln solution, and add a reference to it to our new project.

How to do it…

For this recipe, we will first create a HLSL shader to render our primitive shapes. We will
create a D3DApp class that compiles our shaders and creates instances of our line, triangle,
and quad renderers.

1. The first thing we will do is create our HLSL shader file. Do this by adding a new Text
File to the project and call it Simple.hlsl . Add the following code to the shader file:
// Constant buffer to be updated by application per frame
cbuffer PerObject : register(b0)
{
// WorldViewProjection matrix
float4x4 WorldViewProj;
};
