Season 01 – Episode 41 – Fixing and Mirroring Components

Fixing and Mirroring Components

Title kind of says it all, really.

In a belated follow-up to the investigations and explanations about the maths behind signing angles we fix the only obvious issue that was left with the foot and put our guides to the test by mirroring the now potentially finished components.

Only one bugfix left for the leg FK, if everything goes well, to do in the next stream and then the rig should finally be complete for sharing.

Season 01 – Episode 40 – Learning and Visualizing Maths

Learning and Visualizing Maths

Over one and half hours focused on tools to visulize maths, developing intuition, and understanding correlations. Vectors, Matrices, Trigonometry and Desmos.

I know the math videos are popular, and I had wanted to do something along these lines for a while, and today it took my fancy to give it a shot.
If you care at all about learning maths then this is certainly worth watching, no matter what level you’re at (it’s more about learning than it is about the specific sub topics).

It also comes with some graphs for you to play with:
Rotational Transform
Angle Between

Season 01 – Episode 36 – Finished All Components

Finished Components With Working Symmetry

After warming back up to the rig in the previous stream yesterday this went pretty well, even if I say so myself.

Most of the content is nodelling and reviewing what I’m doing and why, but there’s a good amount of work happening at a relatively snappy pace.

Bugs (presumed) of the previous day are squashed, all components are made to properly guide and deguide, handedness is now considered for the foot too, the foot receives a proper deform layer, our tool for guiding is confirmed working… And more.

It is a nodelling episode, which we’ve had many of, but it’s a good one in my opinion, and it finally takes us to what might be the finish line for all components. I/O and re-assembling the rig should be all that’s left next (unless we will find issues 😉 ).

As for the previous episode I recorded a brief intro which is available in the first link/embed below, you can watch that if you want a quick verbal preview of what goes on in the episode, but it’s mostly what you have just read.

Season 01 – Episode 34 – Everything Else About Mirroring

Mirroring Components, Everything Else

Different format than usual for this episode!

There was a good chunk of work that would be repetitive and boring to do on-stream as nodelling, so unlike in any previous episode I decided to do it off-stream and then bring the rig up to comment on why and how it was done and the underpinning fundamentals.

This is meant to compress the time to finish the rig a bit and offer a more concise episode.

I like how it came out and it seems to have been well received, so it might happen again, albeit probably not this season since the work remaining should generally speaking be new and/or interesting to see through its execution.

So, to make a long story short: This video goes over everything about mirroring components that is required to get a fully reflected component for the leg and shows the rig in action.

I recommend downloading the corresponding ep34 scene from the download section to follow along by exploring the scene as I go over it.
It can be found here as usual.

Season 01 – Episode 10 – IK UpVector and Pop Limit

IK UpVector and Pop Limit

We explain how to introduce an UpVector in our custom IK solver. Following that we take a look at the numbers and reasons behind the classic IK over extension “pop”.

Some nodelling, some applied maths, some maths theory…
It’s a slow but, hopefully, interesting mixed bag this episode

Enjoy,
