@MatN There are several places in the code that will print out this error - "for each frame I get a message "XMLTag::read_tag:326 tag "AUTO", end of buffer"in the terminal." We could not determine the cause and I could not reproduce the error using a static image as background. If you provide a session file, that generates the problem, gg will look at that. |

The 2020-05 released indeed fixed it. Thanks. This can be closed. |

GG made a mod to the program for the "singularity" case to show nothing for the single unrotated frame. Testing was minimal but it was checked into GIT so I will test more tomorrow. |

Thanks! Indeed, deleting a single frame before the first edge-on frame makes it work properly. I tried to put an extra keyframe on the frame that displayed the full frame, but had difficulties getting the proper values. Maybe it is worth putting this workaround or caveat in the manual? If the picture is fully side-on, maybe nothing should be displayed, or just a vertical line? I have not tested any effects of the shadow. While I am at it, the effect's control panel does not show the point number, just "current X and Y". Is it possible to indicate the point number (1-4)? It is difficult to adjust the points when they become close together. The "preset edit" screen shows the number. On a last note, when I play the video showing the problem, for each frame I get a message "XMLTag::read_tag:326 tag "AUTO", end of buffer"in the terminal. Maybe because I used a static image as background? |

This is a case where you end up in the middle with divide by 0. You have to set the X value for the middle keyframe instead of to 0, to a little more, such as .01. And now a word from GG: The interpolated X1..X4 auto coordinates used by perspective eventually have x1==x2, x3==x4, so that all points x are scaled by zero. You also could tweak the frame count so that it is even, so that the center is not over the point where x1==x2, x3==x4, or perturb the midpoint position a little so that the answers are not exactly zero. Any suggestions for what to do in the case of divide by 0? |
