So there's one point that just by looking at it we could say is going to be in our locus.

We also know that the projection of the building on the internal chip is 4mm in size.

And this is f2.

And it's for focus.

And what we want to do is, we want to find out the coordinates of the focal points.

Let's take it right there.

Though graphics hardware can definitely accelerate image processing operations. We'll mostly be focused on 3d rendering in this course.

It's equidistant from a focus and a directrix, where this is the focus.

So let's call that a directrix.

Set here equivalent focal length assuming a 35mm film camera, in mm. A value of 0 means the focal length is unknown.

Well, the first thing you do is though I've never well, we could just figure out the focal length just by plugging into the formula.

So 1 over 4 times 2 is equal to 1 8.

It looks something like that.

And let's say I have some other point.

So what's the reality?

Let's focus on the conversations between our friends and our family and our coworkers and our loved ones.

Or they can be, I don't want to say always.

This doesn't cause any damage.

And it's a center, a focal point for economic and social development.

I'll call that well, we'll call that a focus because it will be a focus.

But where's the focus point?

I'll do it on this right one here.

That's our directrix and it has the equation y is equal to k.

It's not a this is wonderful!

And you enter that space, and you feel like, Wow!

We have focused on the worst case scenario.

And you essentially divide 1 by 4 times this value.

And the remaining piece?

The distance of this point to the image plane up uppercase Z.

Or b which is, remember, what was b?

Just remember, you're going 1 over 4A below the vertex.

This is f1, this is f2.

Requires great focus.
