When I only replaced the image file name with my own image, I got this error.
(I didn't change any other part of the code)

The image size is same(200x200) with the original one with the same format(jpg).
The error message is attached below.

please attach your modified copy of the sketch to this bug report. use
tools -> archive sketch and then click the "create new attachment" link above.

edit]
I only changed input image file (same resolution,size with original pgm)

Since I didn't actually change the code, I only changed the image file, I
doubt that there might be some bug in 'point' function that internally
calculate 2D position of the sketch window from 3D coordinates by projection.
If the generated 2D position is outside of the window, then
arrayIndexOutofBounds error make sense..

k, thanks, will check into it.

fixed for 0151.
