8 Compute reflected, refracted, and transmitted rays

So in this example, the transmittance of number 1 would be the amount that got through over the amount that you put in.

Or you could view that, the transmittance we've already defined, as the negative log of the light that is transmitted over the light that is input.

The dermis already indurated, translucent.

This is transmittance 1.

And so when the people who defined it said, well you know, what we care about is how much is transmitted versus how much went in.

Pass through

Transparent

Over here, the transmittance would be the amount that you got out over the amount that you put in.

transmit

Opaque

Well you could actually use this information.

Or ways of measuring how much light is transmitted versus how much was put in.

Then light began to travel through the universe.

Transparent 1280 x 1024

Transparent 1600 x 1200

Transparent 640 x 480

But the easiest way is the negative log of the transmittance.

And you have some light that makes it through, that exits.

Selection Transparency Color Similarity

And if you were looking at these, this has the least light, this has a little bit more light being transmitted, this has the most light being transmitted.

So if transmittance is a large number, absorbance is a small number, which makes sense.

If you're good at absorbing, that means you're not transmitting much.

Loss of Translucency Information

So let's call this transmittance 2.

Creates a transparent image of 1024 x 768 pixels.

Creates a transparent image of 1280 x 1024 pixels.

Creates a transparent image of 1600 x 1200 pixels.

Creates a transparent image of 640 x 480 pixels.

And so here, we're trying to measure how good is it at absorbing?

So once again, it's going to bump into more molecules and more of it will be absorbed.

To start I sketch the shape of the drop and go over it.

I began to be fascinated by plastic, so I spent four months making eight plastic blocks perfectly optically transparent, as a kind of release of stress.
