Recently I start to study SharpDx, so I am a newbie for it.
I try to create a cube which has difference color on each vertex such as the picture below.
However, what I created after my coding is something I'm not understand such as the picture below.
I have checked my code many time but still couldn't find out what was wrong with it. I hope somebody can point it out for me. Many Thanks.
Hear is My Code
InitializeDirectX:
int width = renderForm.ClientSize.Width;
int height = renderForm.ClientSize.Height;
Rational rational = new Rational(60, 1);
ModeDescription backBufferDesc = new ModeDescription(width, height, rational, Format.R8G8B8A8_UNorm);
SwapChainDescription swapchainDesc = new SwapChainDescription
{
ModeDescription = backBufferDesc,
SampleDescription = new SampleDescription(1, 0),
Usage = Usage.RenderTargetOutput,
BufferCount = 1,
OutputHandle = renderForm.Handle,
IsWindowed = true,
SwapEffect = SwapEffect.Discard
};
SharpDX.Direct3D11.Device.CreateWithSwapChain(DriverType.Hardware, DeviceCreationFlags.None, swapchainDesc, out device, out swapChain);
context = device.ImmediateContext;
RasterizerStateDescription rasterDescription = RasterizerStateDescription.Default();
rasterDescription.FillMode = FillMode.Solid;
rasterDescription.CullMode = CullMode.None;
rasterDescription.IsDepthClipEnabled = false;
RasterizerState rasterizerState = new RasterizerState(device, rasterDescription);
context.Rasterizer.State = rasterizerState;
DepthStencilStateDescription depthStencilDesciption = DepthStencilStateDescription.Default();
depthStencilDesciption.DepthComparison = Comparison.LessEqual;
depthStencilDesciption.IsDepthEnabled = true;
DepthStencilState depthStencilState = new DepthStencilState(device, depthStencilDesciption);
context.OutputMerger.SetDepthStencilState(depthStencilState);
Utilities.Dispose<RenderTargetView>(ref renderTargetView);
Texture2D backBuffer = swapChain.GetBackBuffer<Texture2D>(0);
renderTargetView = new RenderTargetView(device, backBuffer);
backBuffer.Dispose();
Texture2D zBuffer = new Texture2D(device, new Texture2DDescription
{
Format = Format.D16_UNorm,
ArraySize = 1,
MipLevels = 1,
Width = renderForm.ClientSize.Width,
Height = renderForm.ClientSize.Height,
SampleDescription = new SampleDescription(1, 0),
Usage = ResourceUsage.Default,
BindFlags = BindFlags.DepthStencil,
CpuAccessFlags = CpuAccessFlags.None,
OptionFlags = ResourceOptionFlags.None
});
depthStencilView = new DepthStencilView(device, zBuffer);
zBuffer.Dispose();
context.Rasterizer.SetViewport(0, 0, renderForm.ClientSize.Width, renderForm.ClientSize.Height);
context.OutputMerger.SetTargets(depthStencilView, renderTargetView);
My Hlsl:
cbuffer CameraConstant:register(b0) {
matrix World;
matrix View;
matrix Projection;
};
struct VS_IN
{
float4 position : POSITION;
float4 color : COLOR;
};
struct PS_IN
{
float4 position : SV_POSITION;
float4 color : COLOR;
};
PS_IN VS(VS_IN input)
{
PS_IN output = (PS_IN)0;
output.position = mul(input.position, World);
output.position = mul(output.position, View);
output.position = mul(output.position, Projection);
output.color = input.color;
return output;
}
float4 PS(PS_IN input) : SV_Target
{
return input.color;
}

Many Thanks to the one who can point out my problems in these codes.
