Focal point

Thank you. Let's oppose the power of evil systems at home and abroad, and let's focus on the positive.

Aggregate economy. We now have millions of actors.

But where's the focus point?

This doesn't cause any damage.

The focus of the talk is put on the content.

So you need a paradigm shift in all of these areas.

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

Because this point right here, our vertex, is equidistant, it's 1 4 below our focus and it's 1 4 above our directrix.

And this is f2.

And it's for focus.

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 what's the reality?

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

So let's call that a directrix.

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

In this case the major axis is the vertical axis, so the focuses are going to sit here and here, and in this case, the focal lengths are going to be vertical down from the origin and vertical up from the origin, and we get, instead of it being a squared minus b squared, now since b is larger than a, the focal length, which is this, is going to be equal to b squared minus a squared.

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

So we move the decimal point over one here.

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

Five times six is thirty.

Put the one there.

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

This is f1, this is f2.

What is the evidence upon which this is based?

And let's say I have some other point.

Now we're asking you what is the focal length if an object of size 20 m that is 400 meters out if we observe it to be 1 mm on our projection surface.

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

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

Also, we did focus groups with people who were on the ground with kids every day,

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

And you have a point, that's our focus, and it's the coordinate a comma b. that the locus of all points in the xy plane that are equidistant to this focus and this directrix has a shape that

Put this on.

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

But the convention is to often put them in what's called the standard position.
