The stitcher component enables the loading and parsing of
PTGui Pro project files (.pts).
Files saved from the trial version of PTGui will not work as they are encrypted.
PTGui Pro is a panoramic image stitching software which can be
tried and purchased here: ptgui.com/
The stitcher component will parse a PTGui Pro project file and
create the necessary amount of inputs to its component to read
in all involved shots and output the full panoramic texture.
This can be used for real-time video stitching. Use a snapshot of the inputs from all the cameras, send it through PTGui to create a .pts file and then load the .pts file. You can now feed the same cameras into the component and a live-stitch will be performed.
Right now it only accepts inputs from fisheye lens, and outputs equirectangular projection.

Updated to raise a better exception than the one Barak ran into.
Requires builds 54320 or later
[b]The latest Stitcher Component can now be found in the Palette on the left when you first open TouchDesigner. 50000+ series builds of 088.
Out of interest, is it easy enough to adapt for a nadir input from a 5th source?
Also is it possible to to render a spherical camera in TD for compositing back on to the equirectangular? Would this be using a custom projection matrix?
You can render using Cube Map in TD and then use the Project TOP to put that into equirectangular. We also have fisheye and dual paraboloid renders available, but those will suffer from artifacts if your geometry isnât well tessellated. The Project TOP doesnât currently convert those though, so you used need to write those yourself.
Hello to all
Iâm new here and Iâm starting to use TouchDesigner.
I found this component for stitching very useful .
I used the component but I can not figure out how to equalize chromatically all the video sources in real time.
I hope you can help me .
Yes, you could send it out via one of the outputs from the graphics card and capture it using OBS and a capture card. Iâm not too familiar with OBS so itâs possible there is a way to capture on the same machine that is doing the stitching too.
if PTGUI project saved with the lens parameter as âfull frame fish eyeâ (GoPro) Stitcher wonât open it, changing âfull frame fish eyeâ to the âcircular fish eyeâ solves project to TD issue, but than looks like geometry doesnât translate right. Is any workaround possible? Trying to stitch 6 gopro rig
I like it so far. Obviously, it has some limitations but fun to shoot stuff on the go and see it in VR on my phone then and there.
THe Gear 360âs picture is basically two back-to-back fisheye hemispheres that are stitched together for a spherical âVRâ view. Would it be hard to persuade this component to stitch this?
No its not too hard, this is the same image format as the Ricoh Theta camera. You just need a PTGui file for the camera and youâll be good to go. Help is inside the Stitch COMP in readme
Hi, Iâve the same problem as @dimon
The Stitcher refuses to open any PTGui project when the lens parameter in PTGui are set to âFullframe fisheyeâ, which is the correct lens for GoProâs, used in most of the 360 rigs.
Will be very nice to see an update in the Stitcher for fullframe fisheye compatibility.
Thanks
Malcolm mentioned before that we need a .pts file and some sample images of âFullframe Fisheyeâ to look at this. We do not have the required files but if provided for us weâd be happy to test and try to update the Stitcher component. Thanks!
