1;2and3-Point Perspective For Architectural Sketches - Architecture Daily

hi guys Umar here for architecture daily
sketches with another sketch tutorial
now thank you so much for your
engagement on last week's video and also
for your suggestion on this week's topic
which will be perspectives so now I am
going to talk a little bit about the
three kinds of perspectives that we
would do usually for architectural
sketching the general rule of thumbs and
then I'll just kind of you know show how
it could be done really quickly
you know we only want simple sketches
you know for recording ideas and stuff
so I'll go right ahead into the first
one which is one-point perspective now
one-point perspective is the one where
all the lines would converge onto just
one point this would be the horizon line
or your line of eyesight as well again
if you remember in last week's a human
figure tutorial eyes I talked about how
you know this is our line of sight and
how the human figures with just sort of
bobble on that line now if you like to
if you like to know more how to do human
figures you can just watch our video
from last week so anyways for this one
usually you would use a one-point
perspective to show interiors in this
case I think maybe for an example I'll
use a pathway a garden pathway and I'll
just sketch out really quickly how that
would look and populate it with trees
again and also some human figures to
give it some life
so I've drawn an arch here and there's
just a little idea of perspective from
the way the arch from the thickness of
the arch itself now like I said before
is we often use one-point perspective
for interiors because it's kind of
difficult to show form with a one-point
perspective because you know if the
building is like a square building
you'll just be able to see the square
you can't see the size of the building
receding so it's much better for showing
interiors as well now also remember for
shortening when you say like you know if
you're just sketching out really quickly
and you don't have the time to draw
properly with the rulers and guidelines
all the perspective you can still sort
of suss out the foreshortening
of elements like for example you know I
think I will draw a row of trees here on
the side so it would make sense if you
know you start out with a tree like that
but then they just progressively get
smaller and smaller and smaller
it's rather it's all incremental
if you'd like to know how we've draw
trees you can also look at some of our
previous tutorials for this
and again human figures no matter how
far they are the head is always along
the horizon line so this one this guy is
like really far away but you know it's
still
so again that that point about
incremental foreshortening you can see
that in this path the lines as it goes
along it just gets even denser and as it
comes in here becomes more spaced out
and that really helps with this idea of
all of the perspective itself so yeah
that's just a little a little rule of
thumb there so now I'm going to move on
to the second type which is two point
perspective now the two point
perspective is kind of like a human's I
view of a building is often used to show
the form of the building itself like
from the street view so you'd have often
have a guideline like that usually it's
good to choose a horizon line that's
about one-third the way up to the
maximum level of the top of the building
because it will give the impression that
you are looking at it yourself from
street level
so okay guys I've just drawn a two point
perspective here and let me just explain
a few things about it two point
perspective has two vanishing points
here and here and often used in
architectural representation to show
form from the outside you know like an
outside street view and usually for the
horizon line you would choose it perhaps
maybe about two-thirds of the way up of
the whole building to sort of give it
more of an impression of a person seeing
it from the street view and a few other
guidelines that's important to note
about two-point perspective is of course
again the diminishing dimensions and
foreshortening like for example the way
I draw this row of trees is that they
become smaller and denser and they
become closer to each other as they go
along and head to the vanishing point
right here and it's the same with the
windows as well you can see that perhaps
here it's a little bit thicker but as it
goes along it gets a little bit thinner
and more denser as well
those are good rule of thumbs and again
here I've populated it with a few human
figures again also diminishing in their
dimension becoming smaller and one other
tip that I like to include is actually
drawing out windows in sketch I usually
just like to use this zero point six
medium art line pen to just immediately
black out the windows
it's very sketchy but it's very fast you
can already get a sense of depth from
the darkness of the window itself and if
you notice again the way that I drew the
pavement again relates to the vanishing
point right here for instance if you
draw a straight line from here it's
going to go straight to the vanishing
point again here so you can see how each
line is slightly angled and becomes a
little bit flatter more closer to the
horizon line as goes along and also
becomes more denser all of these all of
these
things that you would keep in mind and
discipline yourself towards will create
a very believable looking perspective
even for a simple sketch even for a
really simple ideation sketch
and there you have it guys so this is a
three point perspective or buy you have
a vanishing point here here and here
below now in this case all the vanishing
points are out of the paper space so
it's not visible and this can give you a
bird's eye view now if you invert the
vanishing point from below to above you
can also do that and that will give you
a worm's eye view so that's very
interesting too is very good for master
planning you know showing or for urban
drawing where you want to show all the
urban landscape as well now I played
with the guide lines to the vanishing
point that goes here and here by curving
it a little bit to make it look like a
drone shot you know so there is like a
slight fisheye lens effect you can't
play around a little bit with the guide
lines but you know again if you're not
too confident it's better to keep true
to the rule of thumbs now to summarize
for all three types of perspectives all
of these there are two rules that would
stay true first you have to try and
discipline yourself to try and keep true
to the vanishing points and its
guidelines like for example the
vanishing point is here here and well
somewhere there so of course you have
the vanishing point coming out like that
and the vanishing point here that goes
down it would continue all the way to a
single point of course down there
so when you are trying to consider any
and every element for each of these
perspectives you try and keep true to
these guidelines these access lines and
also the second rule of thumb is to
always take note of foreshortening
which is basically diminishing
proportions and also a denser cluster of
elements so as you get closer and closer
and closer to the vanishing point
everything just becomes denser like the
windows will become smaller and cluster
together up until if you get even close
enough to the vanishing point maybe they
just become like a thick solid thing
that's okay that will actually convince
the whole look of the perspective
actually so there you have it guys if
you keep true to those two rule of
thumbs for all three kinds of
perspectives it's going to look very
convincing even in a short sketch a
really fast sketch or even for you know
a proper drawing with all the guidelines
and using rulers so there you have it
