How to get the projected coordinate of a 3D point?

Hi everyone,

I have a problem about how to get the projected coordinate of a 3D point.

Suppose the 3D point locates at [10 20 30], then I save an image of the scene in current view.

Then, how do I know the coordinate of the 3D point in the saved image?

Does anyone have some ideas?

view.screen_coords returns the point in the Model as X,Y coords - screen value.
But you must ensure that the exported image used the same size as the window, otherwise there is no direct relationship between the point and the image's pixels...
