Cornerpin
-
I have done my testing on a 64 bit OS so 32 vs 64 is not the issue.
-
I think I've found the solution. I also removed the Absolute Quad Distort Actor from the Global User Directory. (since this is the actor that Cornerpin Projector is built on) After that, I inserted the Cornerpin Projector into a scene and all of the settings have been saving after multiple restarts of Isadora. Seems to have done the trick. I'll write again if the issue comes back.
-
That makes complete sense wesley. All of my other click-and-drag actors are based on a lot of the same underlying user actors so in general it might be good practice to use Place User Actor with my mapping stuff until further notice.

Hi Matthew and Wesley,
thanks that definitely does the trick!
Do we need to formally report this as a bug? I do see more need for this kind of WYSWYG interactions when working with projection in space.Also a small question on the following:
if I place a non- 4:3 movie (in this case 16:9) in the Cornerpin Projector MK2 v1.5 the grid is still 4:3 and the deforming of the movie becomes relative to the grid and not fitting the grid itself (i'm using a simple Movie player actor). Is there a way to set the aspect of the source material within the actor?Also I noticed that the Red circles fit the corners of the grid nicely when the stage window is in window mode but are not fitting the corners when in Fulscreen mode. This happened because my window mode is a 4:3 format and fullscreen is 16:9. When i make the window preview the same 16:9 in my settings you see the same problem as in fulscreen mode. This should inply that that people obviously should make sure their settings for window / fullscreen + beamer settings are the same before starting to do some mapping.
-
Oh wait, actually when using the Cornerpin Projector MK2 v1.5 in a 16:9 environment it seems that the red circles don't fit the grid either in window or fullscreen mode. Being not very knowledgeable in Isadora I probably have overlooked something simple...
-
Sorry for this monologue but i have seem to resolved the above issue. Inside the Cornerpin Projector MK2 v1.5 and inside the used Absolute Quad Distort Projector v1.0 I just added a user input to the 'keep aspect' input of the used 3D Quad Distort actor. This I did again at the now visible 'keep aspect' input inside the Cornerpin Peojector MK2 v1.5. Which means the Cornerpin Projector MK2 v1.5 has a toggle for leaving 'keep aspect' on or of for the movie.

Hi jorisw,
I usually work with 4:3 projectors so I apparently neglected to include that. Can you send me the version of the actor where you have made that change so I can put that out as the official one on my site.Thanks,Matthew -
Hi Matthew, of course.
Hope they work at other systems too...

Matthew, have you run into issues with frame rate and Isadora crashing when using the Cornerpin Projector? I'm running about 12 scenes. Each scene has 4 Corner Pin Projectors. I'm only playing still images with them and there isn't any video content in the scenes. The images are all sized to around 800x600, resolution of 72 JPG, or PNG files.
As I move through the scenes Isadora takes progressively more time to load each scene. By the time I get to the 4th, or 5th scene the software crashes.I'm surprised to see this performance issue with such small image files. Playing back the files with the regular Projector actor has no problems. Can you think of anything in the Cornerpin actor that may be causing this? -
I have not seen those issues. The actor is just a ui wrapped around the 3D Quad Distort actor that draws some circles and let you drag them around so it shouldn't have anything in it that would be causing this. Mark may be able to shed some light on the situation.

Hi Mathew,
noticed that the Cornerpin Projector MK2 v1.6 downloadable from your site doesn't show the show aspect input option... Did you already upload the new one? -
I have been in tech so I hadn't gotten a chance to upload the updated version. Its on my short list of things to do.
-
Following up on my last post. I found that setting the Stage Preview Buffering to None helped to resolve the issue with crashing and long load times between scenes. I haven't had another crash.
-
cool, good info, Thnx!
-
Please note that I have put a lot of work into the Stage Preview feature for 1.3.0f25. It will be faster and more robust. So please do give it a try again once you I put 1.3.0f25 up for download.
