示例1: projectPointer
import toxi.geom.Vec3D; //导入方法依赖的package包/类
@Override
public PVector projectPointer(Screen screen, float px, float py) {
ReadonlyVec3D inter = projectPointer3DVec3D(screen, px, py);
// It may not intersect.
if (inter == null) {
return TouchInput.NO_INTERSECTION;
}
// Get the normalized coordinates in Paper coordinates
Vec3D res = screen.getWorldToScreen().applyTo(inter);
// PVector out = new PVector(res.x(), res.y(), res.z());
PVector out = new PVector(res.x() / res.z(),
res.y() / res.z(), 1);
out.y = 1 - out.y;
// Second possiblity... (WORKING) Use directly the 3D location instead of the plane.
// PVector interP = new PVector(inter.x(), inter.y(), inter.z());
// PVector out3 = new PVector();
// PMatrix3D posInv = screen.getPos().get();
// posInv.invert();
// posInv.mult(interP, out3);
// out3.x /= screen.getSize().x;
// out3.y /= screen.getSize().y;
//
// PVector diff = PVector.sub(out, out3);
// System.out.println("Diff " + diff);
// out3.y = 1 - out3.y;
return out;

import toxi.geom.Vec3D; //导入方法依赖的package包/类
@Override

//
// // go from screen coordinates to normalized coordinates (-1, 1)
// float x = (float) undist[0] / getWidth() * 2 - 1;
// float y = (float) undist[1] / getHeight() * 2 - 1;

// 3D intersection with the screen plane.
ReadonlyVec3D inter = screen.getPlane().getIntersectionWithRay(ray);
// dist = screen.plane.intersectRayDistance(ray);
if (inter == null) {
return TouchInput.NO_INTERSECTION;
}
// 3D -> 2D transformation
