我正在使用SharpDX渲染一个点云，使用以下代码：
PointsModel = new PointGeometryModel3D();
PointsModel.Geometry = new PointGeometry3D();
//create positions
PointsModel.Geometry.Positions = new Vector3Collection();
PointsModel.Geometry.Positions.AddRange(
new SharpDX.Vector3[]
{
new SharpDX.Vector3(0,0,0),
new SharpDX.Vector3(10,0,0),
new SharpDX.Vector3(0,10,0),
new SharpDX.Vector3(0,0,10),
});
//create colors
PointsModel.Geometry.Colors = new Color4Collection();
PointsModel.Geometry.Colors.AddRange(
new SharpDX.Color4[]
{
new SharpDX.Color4(1f,0,0,1),
new SharpDX.Color4(1f,0,0,1),
new SharpDX.Color4(1f,0,0,1),
new SharpDX.Color4(1f,0,0,1)
});
//create indices
PointsModel.Geometry.Indices = new IntCollection();
PointsModel.Geometry.Indices.AddRange(
new int[]
{
0,
1,
2,
3
});
PointsModel.Figure = PointFigure.Rect;
PointsModel.Size=new Size(10, 10);在视图中：
<hx:Viewport3DX EffectsManager="{Binding EffectsManager1}"
Camera="{Binding Camera1}" BackgroundColor="#FF88AACD"
ZoomExtentsWhenLoaded="True">
<hx:AmbientLight3D Color="#030303" />
<hx:DirectionalLight3D Direction="{Binding Camera.LookDirection}" Color="White" />
<hx:PointGeometryModel3D Geometry="{Binding PointsModel.Geometry}" Size="{Binding PointsModel.Size}" Figure="{Binding PointsModel.Figure}">
</hx:PointGeometryModel3D>
</hx:Viewport3DX>我希望这些点具有独立的颜色，但我甚至没有将它们设置为红色。无论我如何设置颜色列表中的颜色值，这些点始终呈现为黑色。我遗漏了什么？

我通过将PointGeometryModel3D中的颜色设置为静态值来解决这个问题：
<hx:Viewport3DX EffectsManager="{Binding EffectsManager1}"
Camera="{Binding Camera1}" BackgroundColor="#FF88AACD"
ZoomExtentsWhenLoaded="True">
<hx:AmbientLight3D Color="#030303" />
<hx:DirectionalLight3D Direction="{Binding Camera.LookDirection}" Color="White" />
<hx:PointGeometryModel3D Geometry="{Binding PointsModel.Geometry}"
Size="{Binding PointsModel.Size}"
Figure="{Binding PointsModel.Figure}"
Color="{x:Static Colors.White}">
</hx:PointGeometryModel3D>
</hx:Viewport3DX>但我不明白为什么这是必要的。
点云现在已正确渲染，包括每个点的各个颜色。
