Aug 29th in Drawing, Photo Effects by Alvaro Guzman
In
this basic tutorial, you'll learn how to create a 3D cup from scratch
in Illustrator, how to apply some texture to it in Photoshop, and also
how to use the Vanishing Point filter to mock-up a scenario and apply
realistic shadows.

digital design is a modern form of art, which allows me to explore
innovative techniques, and helps to deliver a clear message to the
public.
My work covers advertising, corporate image, print design, and web
design areas. I am currently the Design Team Leader of SouthMakers.
Final Image Preview
Before we get started, let's take a look at the image we'll be
creating. Click the screenshot below to view the full-size image. As
always, the layered Photoshop file is available via our PSDTUTS Plus membership. You can view the final image preview below or view a larger version here.
Step 1
This is a beginners tutorial, for this we're going to use two of the
most popular filters Displace and Vanishing Point. We'll also use
Illustrator to render the 3D cup.
Let's get it started. First of all open Illustrator, I'm using
Illustrator CS3 to render the cup. Create a new Web Document that is
1024 pixels by 768 pixels. Next, draw a shape with the Pen tool, as in
the image below. Ensure the foreground color is a light gray (#E6E6E6)
and set the Stroke Color as None.
Step 2
Revolve our shape to make it spin from the left or right side, you
can see a detail tutorial about using this technique over at
VECTORTUTS: Working with 3D Objects and Transparencies to Make a Vector Cola Bottle Design, but as this is a Photoshop tutorial I'll keep it simple.
Go to Effect > 3D > Revolve, in the popup dialog click on More
Options and set the following values: Angle at 360º, Offset 0px from
the Right Edge, Surface of Plastic Shading, and Blend Steps set at 100.
Use the following image as a guide. After clicking OK, you'll see how
our ugly 2D shape turns into a nice 3D cup.
The cup's hole must have the same diameter as the cup's base. When you've finished the cup, copy (Command + C) the vector shape.
Step 3
Then open Photoshop, create a new document 1024 pixels by 768 pixels
set to RGB 72 dpi, and paste the clipboard into a new layer (be sure to
paste the cup as a Smart Object). Make the object a little bit bigger
and hit Enter.
Step 4
Duplicate the vector object by dragging the layer miniature over the
New Layer mini-button and go to Layer > Render > Smart Object to
render the copy.
Step 5
Now we're going to create a Displacement Map using the cup's deep
levels. Select the "Cup copy" layer and Right-click (Alt-click) over
it, then select Duplicate Layer. In the popup dialog under the Document
option select New from the drop down and type a name like "map." Save
the new document somewhere.
Step 6
Create a new document 1024 pixels by 768 pixels and paste this image into a new layer. You can create a texture from scratch if you want. I'm using stock this time.
Step 7
Go to Filter > Liquify to make some curves in the vains of the wood texture, as shown below.
Step 8
To apply the Displacement Map go to Filters > Distort >
Displace, set both the Horizontal and the Vertical scale to 10, then
select Stretch To Fit and Repeat Edge Pixels. Select all (Command + A)
and Copy (Command + C) the selection.
Step 9
Paste (Command + V) the document into a new layer above all the
other layers in our main document, then name it "Wood1." Also, change
the layer's Blend mode to Multiply. At this point you must see the cup.
Step 10
Now Command-click the "Cup copy" layer miniature, then Command +
Shift + I to invert the selection. Select the "Wood1" layer, go to
Layer > Layer mask > Reveal All, and fill the selection with
black using the Fill tool (G). Finally, add a new Fill layer as a black
background.
Step 11
Create a new layer below the "Cup" layer, name it "Floor" and select
it. Go to Filters > Vanishing point and draw a plane using the cup's
base as a guide, then expand the plane as much as you want. We're going
to paste the "Floor" texture in this plane, grab this image, or any other, and paste it into the vanishing point plane.
Step 12
There's a nice wood surface to work with. Hide the farthest side of
the surface, show the ruler (Command + R), and drag a horizontal guide.
Select the "Floor" layer and add a Layer mask > Reveal all. Using a
big soft black brush, paint some areas of the layer mask hiding some
areas of the surface. You can use the guide to get a straight line.
Also, you can hide a little bit of the surface's front side.
Step 13
Now we're going to add a background picture, a curtain.
First, flip the image horizontally and paste it into a new layer named
"Curtain." Using the same idea as the previous step, add a Layer Mask
> Reveal all to the "Curtain" layer. Using the same big brush draw
some black areas on the layer mask. Once you've finished hiding the
main areas, change the brush's Opacity and Flow to 50%, and hide more
areas.
Step 14
Now for some Dodge and Burn! Our two best friends. Select the "Cup
copy" layer, then using the Burn tool (O) set to 100px, Hardness 0%,
and Exposure 20%, burn some areas against the light direction. Do this
inside the cup as well. Do it very carefully, and if you need to Dodge
some areas of the cup as well.
Step 15
A quick tip to burn only the inside of the cup. Select the "Cup
copy" layer. Make an elliptic selection covering the entire hole, then
select the Burn tool, and start painting. It only burns inside the
selection, as you can see below. If you want to dodge outside the
selection, Command + Shift + I to invert the selection, then select the
Dodge tool and start painting.
Step 16
Duplicate the "Cup copy" layer, then place it above the "Floor"
layer and below the "Cup copy" layer. Press Command + U to adjust the
Hue/Saturation and set the Lightness value to 100. Select all and cut
(Command + X) the black copy.
Step 17
Go to Filters > Vanishing Point and paste the image over the
plane. Distort the shadow to make it look like the image below. Next,
using a Layer mask or the Eraser Tool, delete some areas of the shadow
next to curtain.
Step 18
Select the "Cup copy 2" (Shadow) layer and go to Filters > Blur
> Gaussian Blur, then set the Radius value in 6px. Set the shadow's
Blending mode to Multiply and Opacity to 85%.
Step 19
As you can see, there's a tiny part over the cup's base without any
shadow. To fix this duplicate the "shadow" layer and paste it above the
"cup" layer, then delete everything but the tiny shadow of the cup's
leg.
Step 20
Paste the dark cup again, but this time into a new layer below the
floor shadow. Press Command + F to re-apply the gaussian blur, then
using a soft Eraser or a Layer mask delete all the extra shadow; We
only need the shadow over the curtain. Finally, change the Blending
mode to Multiply and the Opacity to 75%.
Step 21
Now for an additional shadow detail, duplicate the "floor shadow" layer, make it wider and change the Opacity to 20%.
Step 22
Now, add a bit of liquid to our design - wine is perfect. Show the
Guides and draw two horizontal and two vertical guides tangent to the
cup's hole. Then using the Eliptical Marquee tool, draw an ellipse
using the tangent guides as boundaries.
Step 23
Select the Gradient Fill tool, set the Radial gradient mode, then
change the Foreground and Background colors to #980015 and #4C000F
respectively. Also, fill the selection with the gradient.
Step 24
Move the "Wine" layer a few pixels down. Make the same selection
again, Command + Shift + I to invert the selection. and hit Delete to
remove the selection. Finally, change layer's Blending Mode to
"Overlay."
Step 25
Now you can add more details to the wine, I added two ripples by using a soft white Brush opacity and flow below 50%.
Conclusion
That's it! Of course, you can try to create your very own scene,
design different objects, apply other textures, and get outstanding
results. Try it! You can view the final image below or view a larger version here. Also, sign up to the PSDTUTS RSS Feed to stay up to date with the latest tutorials.
