Examples with IntInt_Obj suite.primitive.IntInt_Obj used on opensource projects

Example 1 with IntInt_Obj

use of suite.primitive.IntInt_Obj in project suite by stupidsing.

the class Render method renderPixels.

public Image renderPixels(int width, int height, IntInt_Obj<R3> f) {
    int nThreads = Constants.nThreads;
    int[] txs = Ints_.toArray(nThreads + 1, i -> width * i / nThreads);
    R3[][] pixels = new R3[width][height];
    List<Thread> threads = // 
    Ints_.range(// 
    nThreads).map(t -> Thread_.newThread(() -> {
        for (int x = txs[t]; x < txs[t + 1]; x++) for (int y = 0; y < height; y++) pixels[x][y] = f.apply(x, y);
    })).toList();
    Thread_.startJoin(threads);
    Image image = new Image(width, height, BufferedImage.TYPE_INT_RGB);
    for (int x = 0; x < width; x++) for (int y = 0; y < height; y++) {
        R3 pixel = limit(pixels[x][y]);
        image.setRGB(x, y, new Color(pixel.x, pixel.y, pixel.z).getRGB());
    }
    return image;
}

Example 2 with IntInt_Obj

use of suite.primitive.IntInt_Obj in project suite by stupidsing.

the class Render method render.

public Image render(int width, int height, BiFun<Float, R3> f) {
    float scale = 1f / max(width, height);
    int centerX = width / 2, centerY = height / 2;
    float[] xs = Floats_.toArray(width + 1, x -> (x - centerX) * scale);
    float[] ys = Floats_.toArray(height + 1, y -> (y - centerY) * scale);
    return renderPixels(width, height, (IntInt_Obj<R3>) (x, y) -> {
        R3 color;
        try {
            color = f.apply(xs[x], ys[y]);
        } catch (Exception ex) {
            LogUtil.error(new RuntimeException("at (" + x + ", " + y + ")", ex));
            color = new R3(1d, 1d, 1d);
        }
        return color;
    });
