Hi, I am trying to convert this to animation filter and webcam filter, the idea seems it is so interesting itself. But it seems the frame rate is very low.
the animate version:
PImage img;
PImage sorted;
float zoff = 0;
void setup()
{
// width and height should be similar to the picture's dimensions
size(1324, 900, P3D);
img = loadImage("Rembrandt_Girl_in_a_Picture_Frame.jpg");
sorted = createImage(img.width, img.height, RGB);
}
void draw()
{
sorted = img.get();
sorted.loadPixels();
println(frameRate);
//for(int f = 0; f < 100; f++)
//{
//int selectedPixel = index;
for(int i = 0; i < sorted.width; i++)
{
for(int j = 0; j < sorted.height; j++)
{
int order = i + j * sorted.width;
float n = warp3D(i, j, zoff, 0.02, 1024);
//int offset = (index-int(n));
int offset = abs(order-int(n));
//println(offset);
//if(offset < 0)
//{
// offset = 0;
//}
color temp = sorted.pixels[offset];
sorted.pixels[order] = temp;
}
}
zoff += 2;
sorted.updatePixels();
background(0);
image(img, 0, 0);
image(sorted, 664, 0);
//image(sorted, 200, 0);
//if(sorted != null)
//{
// //save("RembrandtGirlinaPictureFrame_sortedNoise.jpg");
// noLoop();
//}
}
float warp(int x, int y, float factor, float n_range)
{
float n1 = noise((x + 0.0) * factor, (y + 0.0) * factor) * n_range;
float n2 = noise((x + 5.2) * factor, (y + 1.3) * factor) * n_range;

float n5 = noise(((x + q.x * 4.0) + 8.3) * factor, ((y + q.y * 4.0) + 2.8) * factor, ((z + q.z * 4.0) + 1.3)* factor);
