Creating a 3D sphere
with a shadow on a plane made
from a grid

This
is what we are going to make:
The
first step is to create the grid that our sphere will sit on
1.
Open
Illustrator and create a new document (File >New)
2.
Then with the line tool, draw a straight blue line
a.
You
can change the color by clicking on the color palette underneath the tool bar
b.
Remember
whatever square is in front (the stroke or fill) will be the one that gets
changed. Make sure the “stroke” is the square you make light blue. The fill
square should be set to “no fill.” (see above illustration)
3.
Next
we will duplicate our blue line to create the first part of our grid for our
plane
a.
With
the black arrow tool, select your blue line
b.
Drag
your cursor over your line till you see the cursor change from a single arrow,
to a double black and white one.
c.
This
next part is a two finger work out: hold down the “option” key or “alt” on a
PC, click with your mouse, and then press the shift key. Now with your mouse,
drag a copy of your line. Make sure you let go with your mouse before you lift
your fingers from the “option”, “alt”, of “shift” keys. The “option” or “alt”
key is what allowed us to create a copy of our line, while holding “shift” kept
our new line directly parallel with our old one. Your page should now look like
this:
a.
Now
simply hold “Command + D” (or “Control + D” on a PC) till you have enough blue
lines to create your plane.
b.
Now
select all our lines by using the black arrow tool and drawing a box around all
our lines, or by going “Select>All” or “Command + A”.
c.
Once
all our lines have been selected go “Object +Group” or “Command + G”
d.
Now
we are going to rotate and create a copy of our lines to create the rest of our
plane
1.
Select
the rotate tool
2.
Holding
the “Option” or “Alt” key, click in the center of our group of lines
3.
In
the dialog box, change the angle to 90?. You can check the “preview” box to see
what you have done. Then click “Copy”.
4. If your lines don’t line up perfectly, you can use your black arrow tool to select the group of lines and make them smaller.
e.
Once
you have created a grid you like, our next step will be to skew our plane.
1.
Let’s
select everything we’ve created so far by going “Command + A” or “Control + A”
2.
Then
we will group our objects (Objects > Group, or “Command + G, or “”Control +
G”)
3.
Now
we’ll use out shear tool to give our plane an angle.
4.
Select
the Shear tool in the toolbar
5.
Hold
down “Option” and click in the center of our plane
6.
In
the dialog box, type in an angle of 20?, and a shear angle of -70?. You can
click the Preview box to see what you have made.
4.
Now
let’s create our sphere to sit on our plane
a.
First,
let’s create a new layer for our sphere and lock our layer containing our
plane. That way we don’t accidentally do something to our plane that we don’t
want to.
1.
To
create a new layer, go to the layers palette and click the “create a new layer”
icon. If you cannot see your layers palette, go under the “Window” menu and
click “Layers”.
2.
Rename
your layers by double clicking on the words “Layer 1”, or “Layer 2”. Rename
“Layer 1” – “Plane” and “Layer 2” – “sphere”. Lock the “Plane”
layer by clicking on the lock icon next to the eyeball in the layers palette.
b.
Next,
use your elliptical marquee tool to create a sphere on your plane. Remember if
you hold “shift”, your circle will be a “perfect” circle, holding “option” or
“alt” will start your circle from the center as opposed to the upper left hand
corner. Holding both together will create a perfect circle that starts from the
center. Just remember to let go of your mouse first.
c.
Once
your circle is created, give your circle a radial gradient fill by clicking the
radial gradient in the swatches palette, and get rid of your circle’s stroke.
Remember, if you don’t see a particular palette, you can always go under the
“Window” menu and find it. So far your page should look like the following
page.
d.
By
default, the radial gradient doesn’t make our circle look that 3D. To give it a
more realistic quality, we can use the gradient tool. Remember, to effectively
use the gradient tool, the first spot you click on will be your lightest point,
then you drag your cursor to where you want the darkest spot to be. You can
drag outside your shape.
e.
We
can also make the circle gradient different colors then the default black and
white
1.
Select
the gradient palette, which might be underneath your “stroke” palette, or it
will be under the “window” menu.
2.
Then
make sure you can see your “gradient” options by clicking on the “fly-out menu”
button and selecting “Show Options”. Your palette should look like this:
3.
Now
you can change the color in the gradient by dragging down color swatches form
your “swatches” menu onto the gradient palette crayons. You can drag them on
top of the existing crayons to change the color, or you can drag them anywhere
on the color bar to add additional colors. To delete, a gradient color, select
that crayon and drag it off the palette.
f.
Lastly,
we can create a shadow for our circle so our circle looks a little more
anchored on our plane.
1.
Select
our circle
2.
Hold
“Option” and drag a copy
3.
Using
our black arrow tool, we can squish down our copy of our circle so it’s a
shadow shape.
4.
You
might also want to change the colors back to black and white by filling our circle
copy with the b+w radial gradient in the swatches palette
5.
With
the black arrow tool, position the shadow where you want it
6.
Select
our original circle with the black arrow tool and go
“Object>Arrange>Bring to Front”
7.
With
the black arrow tool, select our shadow and reposition it as needed
8.
To
give our shadow a more realistic look, you may want to open the “Transparency”
palette (behind the “Gradient” palette tab) and change the blend mode from
“Normal” to something else such as “Darken”.
Congratulations!
Your circle should now look something like this:
