Why is it that we shouldn't consider pixels to be squares as Prof. Fatahalian mentioned, especially since a normal computer screen seems to have pixels ordered in a grid-like fashion?

I noticed that the edges of each letter show a faded black perhaps to help it look more continuous than jagged. Is this phenomenon usually captured by the model description or is it a product of rendering the model?

It seems like each pixel is a mix of colors (green, blue, red) - I think he mentioned in lecture that pixels are not just one solid square of color (as shown here with the mix). But can one control regions within the pixel, or is it just adjusting the levels of rgb per pixel, where the r, g, and b are in fixed "locations"?

The way how the colors within each pixel can be altered produce a resulting color that's different from the individual color parts (rgb) reminds me of the Benday dots coloring method common in old comics. Some examples of the Ben-day include: colored sphere and a color chart.

There seems to be a small line of black at the bottom of each pixel, do pixels have some space between them?

@a_s Each pixel made up of rgb components and the color is determined by the voltage applied to the each of those components. By varying the intensities of each component, a pixel can create colors in the RGB color model. Here's a little blurb about how LCDs work that explains a bit more => https://electronics.howstuffworks.com/lcd5.htm
