我正在使用C＃和SharpDX庫在我正在處理的項目上進行一些渲染。但是，我只能夠在第一次傳球時獲得完整的對象，隨後的每次傳球只會得分。如果使用FillMode.Solid或FillMode.Wireframe，則無關緊要。我也禁用撲殺。如果我圍繞物體旋轉相機，我仍然只看到點。我有圖像在我的文件中顯示問題和關鍵點。在過去幾天看過這些代碼後，我完全沒有想法，也許有些新鮮的眼睛能夠弄清楚。DirectX 10 - 完整對象閃爍，然後只繪製點
此外，它似乎只繪製第一個三角形，而不是第二個。
下面是圖片： 
這裏是我的代碼：
網格初始化
rCom.mesh = new Components.Mesh3D(this.render.Device,
new Components.VertexStructures.Color[] {
new Components.VertexStructures.Color(
new SharpDX.Vector3(-1.0f, -1.0f, 0.0f), new SharpDX.Vector4(1.0f, 0.0f, 0.0f, 1.0f)),
new Components.VertexStructures.Color(
new SharpDX.Vector3(-1.0f, 1.0f, 0.0f), new SharpDX.Vector4(0.0f, 1.0f, 0.0f, 1.0f)),
new Components.VertexStructures.Color(
new SharpDX.Vector3(1.0f, 1.0f, 0.0f), new SharpDX.Vector4(0.0f, 0.0f, 1.0f, 1.0f)),
new Components.VertexStructures.Color(
new SharpDX.Vector3(1.0f, -1.0f, 0.0f), new SharpDX.Vector4(1.0f, 1.0f, 1.0f, 1.0f))
},
new[] {
0, 1, 2, 0, 2, 3
}
);

渲染更新代碼
public override void Update(double timeDelta = 0.0f)
{
// Clear our backbuffer with the rainbow color
d3d10Device.ClearRenderTargetView(this.renderTargetView, (Color4)SharpDX.Color.CornflowerBlue);
float time = (float)(timeDelta/1000.0f); // time in milliseconds?
// Do actual drawing here
foreach (RenderComponent com in this._components)
{
// Get any required components
PositionComponent pos = com.entity.GetComponent<PositionComponent>();
// Set up required buffers
var inputAssembler = this.d3d10Device.InputAssembler;
inputAssembler.SetVertexBuffers(0, com.mesh.vertexBuffer);
if (com.mesh.indexBuffer != null)
inputAssembler.SetIndexBuffer(com.mesh.indexBuffer, Format.R32_UInt, 0);
// Set up effect variables
// These matrices should always be defined in the shader, even if they're not used
com.shader.shader.GetVariableByIndex(0).AsMatrix().SetMatrix(this.camera.viewMatrix);
com.shader.shader.GetVariableByIndex(1).AsMatrix().SetMatrix(this.camera.projectionMatrix);
com.shader.shader.GetVariableByIndex(2).AsMatrix().SetMatrix(pos.rotationXMatrix);
com.shader.shader.GetVariableByIndex(3).AsMatrix().SetMatrix(pos.rotationYMatrix);
com.shader.shader.GetVariableByIndex(4).AsMatrix().SetMatrix(pos.rotationZMatrix);
com.shader.shader.GetVariableByIndex(5).AsMatrix().SetMatrix(pos.scalingMatrix);
com.shader.shader.GetVariableByIndex(6).AsMatrix().SetMatrix(pos.translationLocalMatrix);
com.shader.shader.GetVariableByIndex(7).AsMatrix().SetMatrix(pos.translationWorldMatrix);
foreach (var shaderVars in com.shader.vars)
{
// Eventually, we'll use this to set all the required variables needed
}
// Run through each technique, pass, draw
int i = 0, j = 0;
foreach (var techniqueContainer in com.shader.inputLayouts)
{
var technique = com.shader.shader.GetTechniqueByIndex(i);
foreach (var passContainer in techniqueContainer)
{
var pass = technique.GetPassByIndex(j);
inputAssembler.InputLayout = passContainer;
pass.Apply();
this.d3d10Device.Draw(com.mesh.numberOfVertices, 0);
j += 1;
}
i += 1;
}
}
// Present our drawn scene waiting for one vertical sync
this.swapChain.Present(1, PresentFlags.None);
}
最後，我着色器文件
matrix View;
matrix Projection;
matrix rotationXMatrix;
matrix rotationYMatrix;
matrix rotationZMatrix;
matrix scalingMatrix;
matrix translationLocalMatrix;
matrix translationWorldMatrix;
struct VS_IN
{
float4 pos : POSITION;
float4 col : COLOR;
};
struct PS_IN
{
float4 pos : SV_POSITION;
float4 col : COLOR;
};
PS_IN VS(VS_IN input)
{
PS_IN output = (PS_IN)0;
input.pos = mul(input.pos, rotationXMatrix);
input.pos = mul(input.pos, rotationYMatrix);
input.pos = mul(input.pos, rotationZMatrix);
input.pos = mul(input.pos, scalingMatrix);
input.pos = mul(input.pos, translationLocalMatrix);
input.pos = mul(input.pos, translationWorldMatrix);
input.pos = mul(input.pos, View);
input.pos = mul(input.pos, Projection);
output.pos = input.pos;
output.col = float4(1.0f, 1.0f, 1.0f, 1.0f);//input.col;
return output;
}
float4 PS(PS_IN input) : SV_Target
{
return input.col;
}
technique10 Render
{
pass P0
{
SetGeometryShader(0);
SetVertexShader(CompileShader(vs_4_0, VS()));
SetPixelShader(CompileShader(ps_4_0, PS()));
}
}
請讓我知道是否需要任何進一步的信息或代碼。我真的希望有人能幫助我，我無法弄清楚。
