How do you determine which method of rasterizing a line is better? I personally think they all look around the same?

tacocat

Is the diamond rule computationally efficient? It seems like it would require a lot of processing power for a very simple problem.

embl

How are the GPUs efficient for computer graphics?

jonasjiang

I've heard a technique called anti-aliasing. Does this technique use an algorithm similar to the diamond rule?

gfkang

Is this only used for lines on modern GPU's? And what's the advantage (performance or appearance-wise) for doing so?

dchen2

Is there a "circle rule" where they used circles instead of diamonds? What are the advantages/disadvantages of using diamonds instead?

dl123

Is there a specific reason of choosing "diamond" as the criteria here?

spookyspider

How would you be able to tell if the line passes through the diamonds? Would you have to encode coordinates for each diamond on each pixel, keeping estimated "line thickness" in mind, or is there a different approach?

anag

How exactly do modern GPU's compute/store this "diamond" information about the pixels?

minhsual

Are there some ways to quantify how much better one rasterization technique is compared to another kind?

sm022

How is line rendering using the diamond rule parallelized on GPUs? Is the line split into sections drawn in parallel or is parallelism not that important for an individual line?

WhaleVomit

Is the diamond method only used for 0-thickness lines?

shoes

Have there been attempts at improving this "diamond" technique or is it the most efficient we have so far?

Midoriya

Since the line divides every pixel that it touches into two parts, can we calculate the ratio of the area of the two parts and use that as a criteria to decide whether to light up a pixel?

Benjamin

Does everything use the diamond rule or are there other rules that are used?

TejasFX

Are there other rules (i.e circles instead of diamonds) that work better for different orientations / styles of lines and pictures, and are there easy ways to discern as to which rule should be used for a specific image?

large_monkey

What are some examples of other rules that work better for different criteria? Would it be possible to look at some analysis of that? Also, it seems to me that the diamond rule is chosen partly for reasons of computational efficiency on a GPU (just 4 sides of the diamond to intersect against) rather than another shape which would entail more complex operations.

spidey

How exactly do we divide up the pixel in half or determine the diamond shape for our computations? And how do we create this non-zero thickness line to actually do these computations?

Kennen

I am also interested in, is there a specific reason that this diamond rule can help GPU acceleration, or other rules, say circle or hexagon, is equivalent in speed? Then what's the reason for using these diamonds?

coolpotato

How different can a picture look based on the rasterization technique used to light up and color the objects in the picture? Are these differences noticeable to the naked eye?

zijiaow

Are there any other shapes tried to get a smoother line?

Zishen

How we implement the diamond rule?

viceversa

Is there any efficient method to store all those information?

Dalyons

This looks like it would be vulnerable to aliasing on horizontal lines, which are fairly common, since they could be thin but light up two whole rows. Is there a way around that?
