In my application i change the viewingplatform's transform
and immediately after that use the following piece of code to
get the world coordinates from the canvas coordinates
pt - any point on canvas
canvas3d.getPixelLocationInImagePlate(pt.x, pt.y, point3d);
Transform3D temp = new Transform3D();
canvas3d.getImagePlateToVworld(temp);
temp.transform(point3d);
but the points i get are corresponding to the viewingplatform's
previous transform value.
It seems that there is a time lag in transform update and canvas renderer
because on introducing a sleep of few seconds the values are evaluated
correctly.
Now, I have got 3 questions -
1. Is this due to the slow response of renderer thread ?
2. Is there any way by which i could get the notification of canvas
values being
updated after viewing platform's transform change ?
3. Is there any other procedure by which i can evaluate the world
coordinates
corresponding to the canvas coordinates ?
will appreciate any help
regards
Saurabh
