Reflection

No reflection

And I said, No, it's a Stirling engine. But they didn't believe me.

A final instance where things might go wrong is reflective objects that have specular reflections.

Most of the time the entry and exit points are so close together it doesn't matter. But the direction of exit certainly does.

Two changes give a better result, one that's both more plausible and easier to control.

And this is very important light to capture, because this is the light that reflects off the first surface of the skin.

An iceberg that has not experienced as much compression and has a large amount of air and surface edges reflects light as white.

Two dimensional surfaces are usually as far as we need to go.

One idea is to attenuate the specular term by the lumbersian fall off.

Let's look at each of these materials in turn.

Fresnel reflectivity

Meanwhile, the ripples are traveling on the table, and because of the reflections at the top, you see at the back of the bottle, after several frames, the reflections are focused.

What if I were to ask you four is twenty percent of what number? So a lot of people's reflex might just be, oh, let me take twenty percent.

Reflex.

Here's a view of the model with the low shininess and the light coming up from behind it.

From farther away, they may be no change in pixel location.

We also built New York City's first green and cool roof demonstration project on top of our offices.

So the first one is we call solar radiation management, and that's the idea that you could put reflective, mostly reflective particles or other means to make the earth whiter, effectively to increase the earth's reflectivity, reducing the amount of of heat that's absorbed by the sun and therefore exerting some overall cooling tendency on the earth.

Rather their goal is to look reasonable to the viewer.

And blue.

That's a reflex action.

Reflections on puddle.

It's just that in many cases this scattering is over an imperceptably small distance.

The system measures the beam's time of flight, recording the time it takes for the light to hit a surface and make its return.

Redirection

True Reflection

Unlike a normal mirror, it can reflect back the incidental light in the exact same direction.

Some more examples.

By the way, this demo puts all its shaders inside the JavaScript program itself, if you want to look at an example of how that's done.

Yes, because Big Theta is like an equality.

Confusingly, phong invented two cool things.

Assign the shininess, and also assign the specular color to be this.

A mirror reflects light.

Water reflects light.
