I'd like you to identify the types of matrices these are.

In 1979, it had the largest selection of software for any PC. Trs then is the order to remember.

You also have a rotation matrix that will rotate the model or anything else around the y axis.

For example, for the hub cap, here's the series. There's the scale, rotate and translate set for the hub cap itself.

What about a series of scales, uniform or non uniform? Does order matter?

Here's the conceptual diagram of the whole idea.

By putting this object into the clock hand, I'm saying that I want to use the block in its current position.

Then by putting it inside an Object 3D called clockHand, we get an additional scale, rotate and translate that wen can apply.

If you to take a box or a spherical clock hand from their previous exercisers and position it and rotate it, you'll get it something like this.

Translate

We take the multiplicative inverse of each scale factor.

The model's locations are now rotated.

unknown is doing the standard rotate then translate in a series of operations.

Translations can be added together to get a single translation vector.

This is trigonometry.

This is trigonometry.

Finally what about a series of rotations and translations all along the same axis?

Translate this object

And what we can do right over here let's say that this radius is r

The translation of an object by a vector

You want it to stay where it is. You have a few matrices at hand to perform the task.

We had to take corrective action when we transformed normals by a scale matrix, needing the inverse transpose in the worst case.

The answer is to translate, rotate, and then use the inverse translation.

When the run is three, the rise is negative four.

For practice try orbiting fully around your model.

These are supposedly the shortest paths in terms of number of hops to all these nodes.

And that's exactly what we did. delta y over delta x was equal to eight five, or rise over run is equal to eight five.

You're not hard to read at all.

Instead, Andrew will use this style of boring ring

One interesting observation is that the relative fraction or importance of dark matter seems to increase with the radius.

He moved from place to place.

I don't know how many zero's I'm going to need.

I can't, I have only three charges left.

And let's see if that makes sense.

We've seen that 3JS can't easily let us position and rotate the hand of a clock in place.
