示例1: BeginGaussianBlur
public static void BeginGaussianBlur(int radius, float viewportWidth, float viewportHeight, Renderer renderer)
{
if (radius < 1)
radius = 1;
if (renderer.IsDrawing)
renderer.End();
float[] pixelSize = new float[] { 1f / viewportWidth, 1f / viewportHeight };
if (radius > 5)
{
pixelSize[0] *= radius / 5;
pixelSize[1] *= radius / 5;
radius = 5;
}
//Pascal's triangle
float[] kernel = new float[radius * 2 + 1];
float[] t = new float[kernel.Length];

float sum = 1;
