i can do this in real hand draw
but when working using tablet in computer
it s quite impossible for me to achieve perspective circle like this

is there ant special technique behind?
or did he use 3D to set as a low opaque layer?

In Photoshop you can use ellipse tool set on path (top left img). Then use path selection tool, select ellipse and tilt it. In the end right click and select stroke path.
In perspective minor and major axis of ellipse are in slight tilt. As you can see I repeated it with that method.

Feng Zhu probably uses Corel Painter. There is ellipse tool too though it works a little bit differently. Here's some Dermot Power video where he uses ellipse in perspective.

if you use Photoshop... then the vanishing point tool can make working this kind of thing out a lot easier and more accurate...

(you will find it in the Filters Menu)
there's lots of tutorials on the net on how to use it...

No tool will help if you don't understand how a circle looks in perspective. Feng Zhu could get this to look right freehand.

That is absolutely true.. but if you can get the first circle looking correct then the vanishing point tool will speed up creating and placing other circles around the image... it's a great tool...

It's the gentle breeze that kinda hits the forehead then gently slides over the top of ones head and it trails in the wake of "missing the pointness".

Well. I assumed that cerealist knows how to construct circle in perspective and just wonders how to achieve mechanical precision in some of the Feng Zhu images. Lots of stuff about construction is explained in Andrew Loomis "Succesful Drawing" book.

Ah.. I see.. thanks for filling me in:D... well... I'm not really missing the point as I completely understand what the OP was looking for... and yes you can use the PS tool to "help"... especially for digital work... as I have and read lots of books on the subject and seen lots of videos of pros using the tool to work out pespective... and placing "cut and paste" object closer and further from the "camera/viewer"...

..many pros also build stuff in 3d apps and then reference or trace the results for better accuracy...

learning to manually work out perspective is very good advice and takes a lot of practice to nail down but well worth in at the end of the day.

I agree with all of what you write. However the original question from the OP was "how did fengzhu draw perspertive circle like this?"

The answer is simply " Fengzhu understands how circles look in perspective". The answer of "using the perspective filter" creates a crutch if you do not understand what the tool is actually doing and you may use it incorrectly as well. Letting tools fill in gaps of knowledge shouldn't be the answer. Here is an old post (http://conceptart.org/forums/showpost.php?p=2884394&postcount=10) I made some time ago about drawing circles in perspective. This might help some.

From what I understand he can do this traditionally.

Yes Farvus... you are correct... I understood also that the OP was able to do this traditionally and that is why I brought up the the filter idea...

of course knowing how to do perspective stuff is highly beneficial, which he can do traditionaly... so I'm not sure what the answer he's looking for to pull it off digital wise... maybe he is using a mouse... but if so... then the good oulde elliptical marquee is your friend either way.

I understand why you posted stroking a path but I don't really think he can do this traditionally when I read into his post. He would've asked how to make an ellipse in photoshop instead of asking how to do this in perspective like Feng.

If you darken the image you can see a lot of very light guide lines, that certainly looks to me like he plotted perspective. I'm sure he must have used the information from plotting the perspective to indicate where the circles should go, but I doubt they were hand drawn that way as they are very precise and uniform.

My question is why would you bother? Perspective plotting may not be hard once you understand it, but it's still tedious compared to making a simple 3D model to give you the proper guides.

It doesn't look like those are freehand, so probably just plotted out perspective then dropped in elliptical selections and applied a stroke or whatever the equivalent of that may be in painter/whatever other program.

Btw, where did you find that image? I'm a big fan of his and have a lot of his work saved as inspiration to learn from but have never seen that one before; tineye doesn't return any results.

edit Err it seems like the question has been answered already and this is an oldish thread..

Why? you should take a long hard look at scott robertson's work when you ask that question.

My answer to cerealist's question would be that in photoshop you can use transform-> distort on a circle made with the elliptical marquee tool.

make circle formation flat (top view), use distort tool to match perspective

Velocity Kendall

exactly Xyphid. make all the circles in plan view then distort them as one to the desired perspective
