Coordinates change
Hi, I try to make some program that could add on-the-fly objects by following the path of mouse movement.
I use code like this Code:
PointBall = viz.add('ball.wrl') PointBall.color(viz.RED) PointBall.setPosition(e.x , e.y,2) I also make PivotNavigate by mouse on, but disabled left-button function part. The problem is: when I move the mouse on the screen, those generated objects do not follow the trajectory of the mouse cursor, there are some offset. How can I neglect this, and if I zoom in or zoom out the screen, does this method still apply? Thanks |

Try using the <window>.screenToWorld command. Is this what you're looking for?
Code:
import viz import vizact viz.go() viz.link( viz.Mouse,viz.addTexQuad(viz.SCREEN,texture=viz.add('crosshair.png')) ) def addBall(): ball = viz.addChild('ball.wrl',cache=viz.CACHE_CLONE) line = viz.MainWindow.screenToWorld(viz.mouse.getPosition()) pos = vizmat.MoveAlongVector(line.begin,line.dir,10) ball.setPosition(pos) vizact.onmousedown(viz.MOUSEBUTTON_LEFT,addBall) viz.mouse(viz.OFF) |
