Pixel Circle

on: January 14, 2006, 09:23:15 pm
Hello!

I making tutorial of circles. And i view in psp, photoshop, corel draw, paint, etc... the circles are wrong.

In ths image are the perfect circles (without anti-alias)




Perfect circle = A circle made with a curve x4.


And the PSP until with anti-alias the Circle not is perfect




Any program can make perfect circles without AA ¿?

on photoshop you can flood fill a non anti-aliased marquee selection

try making some guides, and then making the selection

circles in photoshop are ok for far..

maybe in psp you have sub pixel precision. I dunno

Image size doesn't matter! It's what you do with your pixels that counts!

yeah its always bugged me how in mspaint the circles are never completely symetrical (most of the small size ones are) but for the bigger ones like.. 10 pixels and up, Ive always flipped and rotated it ontop of itself until its completely symetrical, if you get what i mean

 I would recommend graphicsgale. It's got the circle shape tool for making perfect circles without anti-alias or with anti-alis I hope that helps :D. .

I almost never use the circle tool so I haven't really thought about it. But I'm pretty sure Pro Motion does pefect circles.
Nobody is perfect. I'm nobody.

You think make perfect circles is not important ¿? For my, and for make the tutorial of circle i need make perfect circles to create balls, etc... and if the circles not are perfect...

In this image you can understand the tutorial, and the importantce of make perfect circles.



The tutorial is how to make balls, spheres.. , ilumination, texturize balls (for make rocks,etc..), insert text in balls etc.. in a seconds :)


Kazuya Mochu,

A friend make a circles in photoshop and the circle are not perfect. Are symetrical yes, but not perfects:

Example:



If view the circle (30x30) made in PhotoShop is symetrical, but is not perfect ¿not?

Andy Tran/Mr.Modem

I never need PERFECT primitives for pixel art. Every pixel is pushed anyway, to get the effect I want. The res is so small, why would I or any pixel artist that tweaks manually later on as they should, care if the primitive tool is uneven?  Matriax, as with your other 'tutorials' I fear -whereas interesting- they are only useful to yourself. What with the five, six, seven, twenty five coloured cubes you were making in the past, and now this new ball 'tutorial'.

The cubes etc... i made in the past not is for a tutorial, is for practice with colors, isometric, ilumination etc.. and have a example of color palettes...

Well, i think the tutorials is interesting and i recived comments that the tutorials are useful for other people not only for me (Swiming pool, isometric reflects...) or what you say? (Sorry my english is not very good..)

Well, i have problems with anti-alising or apply AA in circles, and first i will make a perfect cirle and after apply the AA. But if the circle is not perfect and i apply the AA the result...

For example this is the circle, and with AA.



I dont like very much the result, think is a little blur ¿not?


If you not need a Perfect circles, etc.. how will make a ball like this:



You will make this ball pixel at pixel ¿? and if the resolution of the ball is 100x100?
