Welcome back to PJ Chen Design. I usually like to use Rhino to do
everything as possible. This type of shape is actually easier in the
t-spline, but I just want to prove it Rhino can do everything. So let's
take a look on this gecko, and how do we work with the surface like this.
Let's get started!
there are a lot of the image you can use as reference just using the "picture" (command) to
bringing back to the Rhino. We want to able to see it clear, so you can go to the
material here on the right bottom, and you can lower the opacity. so that way it
doesn't like be too strong of the color over there, and then we want to
lock that layer and working from this layer. I'm going to change to the red
color. It's easier for you to see. First of all, we're going to trace basic
outline over there, so we kind of coming over here. Don't worry about eye. We're
gonna get the body first. We want to get something like this and you can
trace it. Get it as close as your design, and I'm going to leave the bottom, the
very end open like that, and let's coming back here. I'm gonna keep tracing.
He has a really big head, and we're just gonna have something like this.
Don't worry about a legs yet. We're going to trace them separately so we're gonna
coming over like this, and again leave the bottom open like
this, and then you can adjust it, and see if the shape is what you like. By
moving the control point at the end, instead of draw it. I would like to
use the blend tool, I'm gonna blend it from here to here, so it's a nice curve
there. Let's go ahead to join all those curves here. I also want to make sure I do
not have that point over there, so the best way to do is rebuild this curve. We
want to rebuild into the less points, but this is too much the deviation over
there, so let me bump it up to 36 and take a look on that. Still, there's a lot
of point missing, so I'm gonna stay actually more than what the
original is. If that is too much of the difference, we can still adjust it
later. Everything else is looking fine over there, so I'm just gonna click
OK. We're gonna adjust it by this way. By moving this over here.
We may want to adjust this points to get more close to the original design.
You also notice after you rebuild it, it will be rounded everywhere, and this the
point it's kind of evenly out. This is what we wanted to get.
The second things we wanted to do is the hand over here, the hand I'm going to do
is having a line starting from inside of the body, and coming over here to get
something like this. I wanted this to be continuous and always back inside of the
body. I'm gonna continue to draw the rest of the feet, so I'm going to speed up
right the video right here.
Now we have all the feet, there that's starting building the main
body first. I'm going to use the sweep. So first things we need to find a rail.
It's gonna use the split command to split from there to there first.
We have two rails over there. We're going to create the cross section. I'm gonna
use the arc tool, We're gonna snapping into the near point from here to
somewhere around here, and want to make sure that it going up like this. Let's do
a test first, we're gonna do the sweep 2 rail. Rail one, rail two with the point
starting with the point right here coming to the cross section, and end it
with the point one more time. We'll get something like this. If
this is what you want that's great. If not, you can keep edit until you get
something that you like. Let me going to lock this one. We are going
to do the cross section on all of them. Let me go ahead to use the Orient 2 points.
We're going to snapping to here to here as a reference point, and we want to
have a copy, and we also want 3D scale. Let's have it coming over here on
every single one. I got an extra there. That's okay we can delete it later, and
having one over here. So you actually don't want this stick it out
from the body, so we wanted to go select a top three of them, and have them go
down. So they are not stick out from the body. You will be fine so make sure they
all stay inside of the body. Each of them it's going to be built by the sweep 2.
So we are going to pick up the curve, and we are going to split with the
point, and somewhere right here. Gonna do that to all of them with the point
somewhere in the middle right here.
At the very last one, we want to split with the point somewhere right there.
Let's go ahead to creating a surface. We want to make sure that we use sweep 2 rail,
and that's a cross session. Before you finish, make sure you record history.
Because that may not be the thickness that we want and we can always
change it later if we do record the history. Make sure that you record
history on every single of them.
Now when we look at this we
might think about okay this may not be what I like, and I do want them to be
higher lower or changing the shape of things like that, so I mean every time
you move you want to move all three pts together, then you'll get something like
that, and then you can keep adjusting. Currently they all surface right now, we
can cap it later on, but I want to finish the whole thing first. The first
things we wanted to deal with those 4 all over here. Let's coming into
the top view, and we're gonna use a sphere. so I'm going to have my seam face up.
and kind of a scale it down something like this. Then we're gonna tilt
it in the way that fitting into the drawing. So we got one there.
We need to have all five of them, so I'm just gonna copy all of them first, and
make sure that you want to rotate it, so the seam is facing outside. I got one
things like this, and that's because we don't want to cut this seam over there.
The next things that I wanted to do is try to do the the bridge in
between, and again I just noticed this might be not be fat enough, so I might
want to keep dragging a line until you you like your design.
I want to kind of edit just a little bit, something like this to make them a
little bit wider, so that will look nicer. I need to draw
the section in between, so I quickly want to draw curve. It's gonna go inside of
the body the same idea with the one for the legs to the body. So we want to have
this coming over here, and this coming over here. Once we have this,
let me Lock this one, and we are going to do some surface there, so I'm going to
simply again using the arc tool, and gonna go from here to here and make sure
they going up with the same thing. Let me go ahead and use the Orient 2 point.
We're gonna have that one snapping into this endpoint to endpoint, copy equal yes,
we do want a 3d scale, and we want to go from here to here here to here, and
you're just gonna do bunch of cross section here to here.
okay so I just noticed those ball are not right at the same level so just
using the align tool to a line to a line horizontally to the zero. Now we
got something like this, and I may want them to be a little bit skinnier, they're
skinnier and don't forget to do the bottom. it will be much easier then do
them separately, so I'm just going to create a line. I should have done that
before I do the Orient 2 point, but it's only five of them, so I'm just gonna
do something like this, and we wanted to join this and this one, and become a
closed curve. So let's give it a try, sweep two, rail one, rail two,
cross-section, so let's do the fillet the edges. We want to pick up here, here,
here. this is kind of a tight over there. I might also want to pick up this one.
We'll fillet it all the way to the end, and then apparently this one is over that
line. I just want to make sure that goes smaller and let's give it a try.
Now it's smooth all the way to the end. we're gonna do the same
thing for all rest of it. so I'm going to fast forward the video.
Now we finish the feet. We can go ahead to boolean the rest of the body to
create the eyes, what we like to do is creating an outside shape. I'm going
to use the curve, and to draw something look like something a little bit puffy
like there, and I can make this - little bit lower so they will look a little bit
rounder something like this. And we're going to simply just using the revolve.
We will revolve this guy from this point to that point for 360 degree.
We get this dish looking things, and I'm going to also using a sphere and kind of
a create some sort of sphere right there. So you can get to surface right there.
I can make this one go up a little bit, so that look like an eye or
something. We can boolean this, and to get this eye smaller and even smaller
That would be the eye we want to play with, and I'm going to using the
command Orient on Surface, and this is the guy I'm going to orient it on the
bottom. and to this surface over there. Make sure the Rigid is not check, and
then we wanted to click OK. Make sure you want to have a copy, so I have one over
there, and the other one will be approximately right there. Now we got
this one there. If it is too much outside, that's okay. We can simply just bring
them in a little bit or when you try to do the surface orientate, you might want
to set up some sort of a reference point so you can get them
be lower. Let me delete this curve over here. If that look all right
to you, let's go ahead to boolean, and then having the eyes stick it out that
much is just weird. so let's give it a fillet edges on every single edge that we
can find, and also on this one as well. So that will be the tutorial to using the
Rhino to build this organic gecko shape. The big thanks to Karen Chartier. here thank
you very much for your donation. It make a huge difference to the small YouTuber
like me. That helped me release my other duties, and create more video. Thank you
very much and thanks everybody for your watching. Please like and comment my
