Q Light Controller+

For a moving head, I would like to be able to define two endpoints with Pan/Tilt and Pan Fine/Tilt Fine, and then be able to specify a duration of movement between the two endpoints. An algorithm will calculate the number of midpoints possible to transmit given the duration, and then smoothly as possible send new pan/panfine/tilt/tiltfine values to the fixture in every iteration. In addition, the ability to specify a fader in the virtual desktop that would allow the user to move the head between the two endpoints manually.

All of this is already possible. Example attached. Keep an eye on the pan/tilt channels.

Going through these topics, you'll notice that you live in a 3D world with your lights and that you 'only' have 2D controls (pan tilt).

I made a few changes to Yestalgia's example.

...and then be able to specify a duration of movement between the two endpoints ....

On the left side i added a Loopback Slider to control the Fade Speed.
Furthermore i added some buttons to set the Fader to some predefined values.
Feel free to set the Range of the Speed Dial and the values of the Sequences to whatever you need.
Remark: the Loopback channels are all set as LTP.

the ability to specify a fader in the virtual desktop that would allow the user to move the head between the two endpoints manually.

Next to that i added a Cue List with a Cross Fader.
I used a Loopback Slider on this Cross Fader, where the range is limited from 2 to 253 (that way preventing the Cue List to "Flip over" from one scene to another).
This Loopback Slider is placed on top of the Cross Fader of the Cue List.
Remark: make sure that the Pan and Tilt channels used in your scenes are set to "Can Fade".

Wow, thanks. I can’t wait to try this out.
