    Dans cette vidéo, Mark Krly explique comment dessiner en perspective à trois points, en utilisant un bâtiment comme exemple. Il souligne l'importance de placer correctement les points de perspective pour éviter une distorsion, semblable à un effet de lentille fish-eye. Il commence par dessiner un rectangle en utilisant des lignes verticales et horizontales, puis il ajoute des détails pour créer une structure réaliste. Mark montre également comment utiliser des lignes de perspective pour dessiner un personnage humain, en veillant à ce qu'il semble ancré dans l'environnement.

    Ensuite, Mark introduit un droïde flottant dans la scène, en commençant par une forme simple qui respecte les règles de perspective. Il explique comment dessiner un cercle sur une surface carrée en utilisant des subdivisions pour guider le dessin. À la fin, il ajoute de l'encre aux lignes et encourage les spectateurs à appliquer ces principes de perspective à leurs propres dessins, tout en remerciant ceux qui soutiennent son travail.

  • 00:00:01
    hey there everybody it's Mark krly I'm
  • 00:00:03
    back with another how to draw video
  • 00:00:04
    today we're going to be learning about
  • 00:00:05
    three-point perspective that's the kind
  • 00:00:07
    of drawing that you do when you want to
  • 00:00:09
    do a sort of a bird's eye view so we
  • 00:00:11
    have an office tower here and you can
  • 00:00:13
    see one two three points okay and all of
  • 00:00:17
    the uh horizontal lines on this side of
  • 00:00:20
    the building are going off toward that
  • 00:00:21
    point all of the uh lines over here
  • 00:00:24
    heading off toward that point and what
  • 00:00:25
    turns it into a three-point perspective
  • 00:00:27
    is you have a uh point at the bottom
  • 00:00:29
    where of the vertical lines are pointing
  • 00:00:32
    uh in that direction now there's a
  • 00:00:33
    problem with this drawing as I look at
  • 00:00:36
    it I think it looks distorted it's sort
  • 00:00:38
    of looks like a fishee lens and that's a
  • 00:00:40
    problem that happens when you draw the
  • 00:00:43
    three points uh or you place them too
  • 00:00:45
    close together I'm going to pull back
  • 00:00:47
    now and show you um where to properly
  • 00:00:49
    place these points so as not to get this
  • 00:00:51
    distorted final
  • 00:00:53
    product okay so I'm doing a little
  • 00:00:55
    handheld photography here to show you uh
  • 00:00:58
    we got one point here we got another
  • 00:01:00
    right here both of them outside of the
  • 00:01:03
    panel frame where we're going to be
  • 00:01:04
    doing the final art and then way down
  • 00:01:07
    here that's where that dot is now you
  • 00:01:09
    might ask me how many inches well it
  • 00:01:11
    depends on how large your paper is but
  • 00:01:13
    just kind of eyeball it and figure
  • 00:01:15
    that's the uh distances that you need to
  • 00:01:17
    have so that the drawing here in the
  • 00:01:19
    middle will be accurate three-point
  • 00:01:22
    perspective well let's not waste any
  • 00:01:23
    more time let's get on to the actual
  • 00:01:25
    lesson okay well I'm going to begin by
  • 00:01:27
    doing this all real time the very first
  • 00:01:30
    part of it anyway and then you can sort
  • 00:01:32
    of get the basic uh idea of how to to do
  • 00:01:34
    at least one object in um three-point
  • 00:01:37
    perspective so I'm starting with a few
  • 00:01:39
    lines here these are going to be those
  • 00:01:40
    uh vertical lines uh like I showed you
  • 00:01:43
    uh in the first drawing hopefully um
  • 00:01:46
    getting a nice sort of even spread and
  • 00:01:49
    you know part of the reason I did that
  • 00:01:50
    handheld thing where I showed you the
  • 00:01:52
    whole thing I there's no way I can fit
  • 00:01:54
    all three of the dots in into this video
  • 00:01:57
    frame but I can at least get these two
  • 00:01:59
    and then you you know saw before you can
  • 00:02:01
    hopefully remember where I did that so
  • 00:02:03
    this is I'm making sort of a rectangular
  • 00:02:05
    box here and uh I'm going to uh drop in
  • 00:02:08
    a line here that's going to be the um
  • 00:02:11
    lower edge of that
  • 00:02:13
    box and then uh the upper Edge uh is
  • 00:02:16
    going to come right around here this
  • 00:02:20
    will maybe be the far edge of it all
  • 00:02:23
    right and let's just drop in um this
  • 00:02:26
    line here I know it's a little hard to
  • 00:02:27
    follow what I'm doing here cuz they they
  • 00:02:29
    just sort of look like random lines but
  • 00:02:32
    here's where the magic
  • 00:02:34
    starts and I try to pull them together
  • 00:02:38
    to create a um you know it'll start to
  • 00:02:40
    look like a standing rectangular box now
  • 00:02:44
    as usual I hate to do these things it's
  • 00:02:46
    just sort of hypothetical um uh drawings
  • 00:02:50
    i' I've tried to imagine a scene uh
  • 00:02:53
    almost a narrative scene from a story uh
  • 00:02:56
    that I'm going to be illustrating as we
  • 00:02:57
    go along um but to begin with you know
  • 00:03:00
    basically it's just looking like a
  • 00:03:02
    standing uh rectangular box and
  • 00:03:06
    hopefully that shows you how I would use
  • 00:03:08
    these uh three different points uh to
  • 00:03:10
    create something that is of uh realistic
  • 00:03:13
    you know that avoids that problem I
  • 00:03:16
    showed you earlier of the kind of fishey
  • 00:03:18
    or overly distorted type of three-point
  • 00:03:21
    perspective now uh I'm not going to be
  • 00:03:24
    doing real time for all of the various
  • 00:03:27
    uh components of this illustration but I
  • 00:03:29
    wanted to at least this first one in
  • 00:03:30
    real time so you can see you know about
  • 00:03:32
    how much time it takes to render
  • 00:03:34
    something like this and indeed it does
  • 00:03:36
    involve a lot of erasing you saw me do
  • 00:03:38
    just then because you know when you're
  • 00:03:39
    first beginning you don't know exactly
  • 00:03:41
    where the box is going to be where where
  • 00:03:43
    these lines need to stop so I'm going to
  • 00:03:46
    go ahead and in time lapse add um a
  • 00:03:48
    surface up here I'm imagining that this
  • 00:03:51
    so-called box is actually a structure on
  • 00:03:53
    the roof of a building okay so bear with
  • 00:03:55
    me in time lapse I'm going to draw the
  • 00:03:57
    rest of the roof of the building
  • 00:04:04
    okay so uh we've got this is the sort of
  • 00:04:06
    edge of the rooftop um and it's looking
  • 00:04:09
    very blank and kind of overly simplistic
  • 00:04:12
    right now so what I'm going to do is go
  • 00:04:13
    in and add some sort of surface
  • 00:04:16
    rectangles and so forth that help to uh
  • 00:04:18
    delineate this surface make it a little
  • 00:04:20
    more solid looking again all in time
  • 00:04:22
    lapse
  • 00:04:23
    [Music]
  • 00:04:40
    all right so you can see how adding
  • 00:04:41
    these little extra lines helps to sort
  • 00:04:44
    of solidify things a little bit and you
  • 00:04:46
    know generally speaking if you want to
  • 00:04:48
    keep things simple for yourself you are
  • 00:04:51
    um making almost every line uh agree
  • 00:04:55
    with one of those uh three dots that you
  • 00:04:58
    put at the beginning you know uh
  • 00:05:00
    realistically yes certain things on the
  • 00:05:02
    surface of the building in real life
  • 00:05:04
    might be at some kind of an odd angle
  • 00:05:07
    and you know you can do your best to
  • 00:05:08
    replicate stuff like that but I you know
  • 00:05:10
    for me I like to just sort of keep it
  • 00:05:11
    simple and say let's pretend that the
  • 00:05:13
    entire surface of the uh rooftop is
  • 00:05:16
    covered by uh you know what do you call
  • 00:05:18
    that per perpendicular lines or you know
  • 00:05:21
    lines that create all right angles and
  • 00:05:23
    that just makes it very easy to uh uh to
  • 00:05:25
    draw the picture now I want to do
  • 00:05:27
    something here uh that um becomes tricky
  • 00:05:30
    uh drawing a figure a human figure in
  • 00:05:33
    three-point perspective um because of
  • 00:05:35
    course a person is not going to be all
  • 00:05:37
    in um you know uh uh right angles the
  • 00:05:42
    human body has never done that way so in
  • 00:05:44
    a way you have to kind of fake it but by
  • 00:05:46
    putting a few lines in place a few
  • 00:05:48
    vertical lines uh say and maybe just a
  • 00:05:51
    couple of uh horizontal lines you can
  • 00:05:54
    sort of help to give yourself a sense of
  • 00:05:56
    where this human figure would stand
  • 00:05:58
    again I'm going to do this in timelapse
  • 00:05:59
    I'm trying to cover an awful lot of
  • 00:06:00
    stuff in this video but hope you you'll
  • 00:06:02
    see how I make use uh of these lines in
  • 00:06:05
    fact why don't I zoom in I'll zoom in so
  • 00:06:07
    that you can see in Greater detail what
  • 00:06:09
    I'm doing
  • 00:06:10
    [Music]
  • 00:06:17
    here all right so I don't know how
  • 00:06:19
    perfect the anatomy is here but you
  • 00:06:21
    could kind of see how I used th those
  • 00:06:23
    initial lines to get a sense of you know
  • 00:06:25
    his shoulder would follow here and like
  • 00:06:27
    here's an example uh if I use um the
  • 00:06:30
    this perspective system to figure out
  • 00:06:32
    where his knees would fall right or the
  • 00:06:35
    tips of his toes um these kinds of
  • 00:06:39
    things can help you to to get a a more
  • 00:06:41
    accurate you know because part of the
  • 00:06:42
    problem when you try to drop a figure
  • 00:06:44
    into this uh three-point perspective
  • 00:06:46
    sometimes it looks like they're not
  • 00:06:47
    actually standing on that rooftop you
  • 00:06:49
    know what I mean uh it can it can just
  • 00:06:51
    look off in a certain way and so I'm
  • 00:06:53
    trying to show you how do you fit a
  • 00:06:55
    figure into um uh a pre-existing
  • 00:06:59
    environment like this and I think most
  • 00:07:01
    artists are kind of using some system a
  • 00:07:04
    little bit like this you know to
  • 00:07:06
    whatever degree you can find uh uh um
  • 00:07:08
    some help with those perspective lines
  • 00:07:10
    that can help you get the figure to look
  • 00:07:12
    like he's actually standing firmly on
  • 00:07:14
    top of that roof all right now I'm going
  • 00:07:16
    to pull back and add one more element to
  • 00:07:18
    this
  • 00:07:19
    drawing okay so you can see I've got
  • 00:07:21
    this guy he's sort of holding a uh rifle
  • 00:07:24
    of some kind he's hiding behind this uh
  • 00:07:27
    structure that we began drawing and for
  • 00:07:29
    some reason I feel like going into
  • 00:07:30
    sci-fi mode again and I thought I would
  • 00:07:33
    draw some floating Droid like an
  • 00:07:35
    assassin Droid or something that's
  • 00:07:37
    floating by here and he's hiding with
  • 00:07:38
    his gun so let's go ahead and drop that
  • 00:07:40
    in and show how you can add an extra
  • 00:07:43
    object and still have it fit into the
  • 00:07:45
    scene by using your three-point
  • 00:07:47
    perspective
  • 00:07:51
    scheme so I thought I would kind of
  • 00:07:53
    interrupt myself just a little bit to
  • 00:07:55
    show you how I begin to build this Droid
  • 00:07:58
    I'm starting um regardless of what the
  • 00:08:01
    final shape of it will be I'm starting
  • 00:08:02
    with this simple rectangle that obeys
  • 00:08:05
    all these rules of perspective then I
  • 00:08:07
    can go in and start adding different
  • 00:08:09
    details and so forth um on top of it so
  • 00:08:12
    that it doesn't just look like a big
  • 00:08:13
    floating block but I wanted you to get
  • 00:08:15
    the sense that you you build on top of a
  • 00:08:17
    simple structure that indeed relates to
  • 00:08:20
    all of those three points so let's go
  • 00:08:22
    ahead and turn this into a cool looking
  • 00:08:24
    Droid
  • 00:08:30
    so I'm making progress uh in uh the you
  • 00:08:32
    know construction of this Droid and I
  • 00:08:34
    thought this might be a good opportunity
  • 00:08:35
    to show you how do you fit a circle uh
  • 00:08:38
    into a square surface like this I'm
  • 00:08:39
    going to zoom in and show you the
  • 00:08:41
    step-by-step technique of doing that
  • 00:08:43
    okay so you may sometimes find yourself
  • 00:08:45
    trying to draw a circle that fits flat
  • 00:08:48
    on the upper surface of this thing and
  • 00:08:49
    you're like well how do I do that oh boy
  • 00:08:52
    it's not really fitting this is looking
  • 00:08:54
    really weird to me so let me show you a
  • 00:08:56
    good technique for doing that um uh and
  • 00:08:59
    it begins oddly enough with a
  • 00:09:02
    square um and you start by using your
  • 00:09:05
    again your three points to draw a square
  • 00:09:08
    on the upper surface of this object okay
  • 00:09:11
    so I'm just sort of dropping this in as
  • 00:09:13
    fast as I can and then once you've got
  • 00:09:16
    that square in place you can choose to
  • 00:09:20
    even further subdivide that um you know
  • 00:09:23
    into like uh
  • 00:09:26
    quarters and finally once you've got
  • 00:09:28
    something like that in place that will
  • 00:09:31
    sort of allow you to little by little
  • 00:09:33
    inch your way
  • 00:09:35
    toward a circle right one by one I'm
  • 00:09:38
    sort of Connecting the Dots here in such
  • 00:09:41
    a way that these lines will fit into
  • 00:09:43
    that square right and uh you know it
  • 00:09:46
    takes a little practice to get used to
  • 00:09:48
    doing this but hopefully by the time
  • 00:09:50
    you're done with that you've got a
  • 00:09:52
    circle that's laying flat upon the
  • 00:09:55
    surface uh of this object and then you
  • 00:09:58
    can kind of go to town building things
  • 00:10:00
    on top of that which I'm going to do
  • 00:10:01
    right now in
  • 00:10:03
    [Music]
  • 00:10:14
    [Music]
  • 00:10:16
    timelapse okay so you can see how I used
  • 00:10:19
    three-point perspective to create all of
  • 00:10:20
    the different parts of this illustration
  • 00:10:22
    including uh dropping the figure in uh I
  • 00:10:25
    don't know about you guys but I can sort
  • 00:10:26
    of imagine this being a scene from a
  • 00:10:28
    Star Wars movie right
  • 00:10:29
    why have you not yet located the rebel
  • 00:10:32
    informant we have dispatched an assassin
  • 00:10:35
    Droid your
  • 00:10:37
    lordship okay I'm getting a little
  • 00:10:39
    carried away here uh in any case I hope
  • 00:10:42
    you found this useful I'm going to go
  • 00:10:43
    ahead and jump into um uh time lapse to
  • 00:10:46
    just add ink to all of these lines I'm

    not going to go full scale into coloring
  • 00:10:50
    this time I think I might be able to do
  • 00:10:52
    what I did last time and create a
  • 00:10:53
    separate video in which I do some
  • 00:10:55
    coloring or uh introduce different
  • 00:10:57
    aspects to this lesson but for now let's
  • 00:10:59
    kick it into time lapse and add ink to
  • 00:11:02
    all of these

  • 00:11:28
    finished drawing I hope this taught you
  • 00:11:30
    uh some useful information about
  • 00:11:32
    three-point perspective how to use it to
  • 00:11:34
    uh draw pretty much anything not just a
  • 00:11:36
    Sci-Fi thing like this but apply these
  • 00:11:38
