Example 11 with Matrix4

use of org.rajawali3d.math.Matrix4 in project Rajawali by Rajawali.

the class Renderer method unProject.

public Vector3 unProject(double x, double y, double z) {
    x = mDefaultViewportWidth - x;
    y = mDefaultViewportHeight - y;
    final double[] in = new double[4], out = new double[4];
    Matrix4 projectionMatrix = getCurrentCamera().getProjectionMatrix().clone();
    Matrix4 MVPMatrix = projectionMatrix.multiply(getCurrentCamera().getViewMatrix());
    MVPMatrix.inverse();
    in[0] = (x / mDefaultViewportWidth) * 2 - 1;
    in[1] = (y / mDefaultViewportHeight) * 2 - 1;
    in[2] = 2 * z - 1;
    in[3] = 1;
    Matrix.multiplyMV(out, 0, MVPMatrix.getDoubleValues(), 0, in, 0);
    if (out[3] == 0)
        return null;
    out[3] = 1 / out[3];
    return new Vector3(out[0] * out[3], out[1] * out[3], out[2] * out[3]);
}
