Hey, how about tring some 3-point perspective !?

hm. I can see why really only need 2 or so i am told

It was very famously used back in 1973 by Ridley Scott (Alien, Bladerunner, Gladiator, etc) for an advert for bread - which has repeatedly been voted "best advert ever":

Which certainly shows what that hill is like (as well as being, as always by RS, very beautifully photographed - he started out in ads, but this is the one that gave him the break into movies).



I prefer this version. Clickety! smile.gif

i think its kinda horrible sad.gif i'm still strugling with perspective too...
em... please dont scold me for my drawing ok? unsure.gif
or maybe someone can give me a tips about perspective?

smile.gif Nobody gets scolded for their efforts here. Looking at your drawing, you have the viewpoint too high. Almost like you were looking down from a high bulding. if you lower the viewpoint, your seating needs to exit the picture at a higher point. Like this.

This brings the viewpoint down to a more natural level. Try it and you'll see how that works. smile.gif

thanks for the tips happy.gif i will try to draw it again but i will do it after i finished my homework from the collage smile.gif
yunmi
i did it! happy.gif

When a regular subdivision (part (A), seen from above) is put in perspective, we can draw approximately as in part B (see the above drawing of Songsparrow) . But how to draw the horizontal lines correctly, following the law of perspective ? I've raised the challenge in Kay's topic.
NVA
A rectangular figure ABCD (figure (A)) has, in one point perspective, the form A'B'C'D' (figure C). The vertical edges converge to the point O on the horizon line.
The problem is how to draw in perspective the division of the rectangle ABCD into 4 equal parts.
I suggest the following method.
You divide the rectangle ABCD vertically also into 4 equal parts, and draw one diagonal. Notice the intersections of the diagonals with the subdivision lines.
In perspective (A’B’C’D’), all the vertical lines converge to the point O. The diagonal remains a diagonal in perspective. Therefore you can determine the intersection points. These intersection points give you the references to draw the horizontal lines in perspective.
(see the next comment for the case of irregular divisions)
NVA
For the case of irregular subdivisions, you can proceed as follows:
Let, for example, the figure ABCD, divided into inequal parts. Then you first draw the diagonal. From the intersections of the diagonal with the division lines, you draw the vertical divisions to get the points E and F. In perspective, the relative proportions between D, E, F and C are conserved. Therefore you can determine the points E' F' on the line D'C'. From E' and F' you draw the converging lines to O. These lines gives the intersections with the diagonal in A'B'C'D'. From these intersection points, you draw the horizonal lines in perspective.

Forgot about this post! Sorry NVA. Your illustrations are very good Well done! smile.gif Dave (dcorc) posted up some excelent animations that may cover this subject. But I can't find them? So I have quickly cobbled together a very simple animation that may go some way to explain the simpler aspect of this subject.

See it here.

Sure would have been nice if the teach in the drawing 101 class I took could have showed us this..
I knew there were tricks and techniques for making things more understandable.

Now how did you figure out the short end line lengths on the far ends or was that just arbitrary?

Knocked this up in just a few minutes. I didn't really take note of the left hand side of the cube, instead, concentrating on how to divide up the right hand face. So in fact, the perspective is more than likely not correct vis a vis the vanishing points!

I saw Dave very good animation. His illustrated the case of division into 2 or 4 equal parts. For general divisions into inequal parts, see my comments. Well, all this to understand the principle. In practice, we all draw approximately!
