我想用 Win2D 库创建绘图。我已经完成了，但是当我想重绘更大的图纸时遇到了一些性能问题。这是我用来显示绘图的解决方案：

private Microsoft.Graphics.Canvas.Numerics.Vector2[] trianglePoints = new Microsoft.Graphics.Canvas.Numerics.Vector2[3];

private void RenderTriangle(List<Triangle> TriangleList)
{
            using (var drawSession = renderTarget.CreateDrawingSession())
            {
                CanvasPathBuilder pathBuilder = new CanvasPathBuilder(Win2DCanvas);

                foreach (Triangle triangle in TriangleList)
                {
                    trianglePoints[0] = triangle.vertexA;
                    trianglePoints[1] = triangle.vertexB;
                    trianglePoints[2] = triangle.vertexC;

                    triangleGeometry = CanvasGeometry.CreatePolygon(Win2DCanvas, trianglePoints);

                    pathBuilder.AddGeometry(triangleGeometry);

                }
                drawSession.FillGeometry(CanvasGeometry.CreatePath(pathBuilder), color)
        }
}

主要问题在于这一行：

triangleGeometry = CanvasGeometry.CreatePolygon(Win2DCanvas, trianglePoints);

创建大约 100 000 个多边形需要大约 6000 毫秒，这是令人难以置信的长时间。

你知道在 Win2D 中渲染大量三角形的更快方法吗？

我应该在 C++ 中创建多边形并将它们包装到 C# 或其他东西吗？

感谢您重播。
