Polar co-ordinates with equations
- [Instructor] Let's have a look at distorting this image using the Equations filter once again, but this time we'll change it to polar coordinates. Here R stands for radius and T stands for theater, and by theater they mean angle. They can't use A for angle because A is used for the A Parameter. Let's try changing the theater. We can change this to T times A, so it's multiplying it by whatever parameter we put in A, and then as we drag this slider you can see how it bends the image in on itself. And it'll continue bending it in until we get round to a full circle. We can produce some interesting effects using mathematical equations once again. So let's set our radius to, radius, the original radius, times, the cosign of the radius, and that gives us this interesting spherical effect. If we then multiply that by our B slider, we'll use B because we've already used A up here. We can now drag the slider and it moves the image around within this spherical distortion. And we can add our T…
