Algorithms Circle

AI Thread Summary

Algorithms for drawing circles in computer graphics include Bresenham's circle algorithm, which is efficient for rasterizing circles on a pixel grid. This algorithm uses integer arithmetic to determine which pixels should be illuminated to form a circle, minimizing floating-point calculations and improving performance. Another common method is the midpoint circle algorithm, which also focuses on symmetry and incremental calculations to achieve smooth curves. Resources such as gamedev.net provide additional insights and examples for implementing these algorithms effectively.

Adam

I don't have a computer graphics textbook, but I need to figure out the algorithms for drawing circles. Bresenham, and I think another one. Anyone got some notes or tips about this stuff?

Thread 'MS 365 Profile Badge colour'

Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...

Thread 'ChatGPT Examples, Good and Bad'

I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...
