You can create your own red/blue 3D images to print, or look at on a computer screen, using a normal digital camera and some image processing software. For this activity we explain how to use Adobe Photoshop, but you should be able to get the same results using similar programs by playing around with the tools and settings.
To recreate this 3D effect in print or on a computer screen, we need to simulate binocular vision. In short, we need to take two photos of our subject, separated by a short distance (the distance between your eyes: about 3 inches), then make it so your left eye only sees the left image and your right eye only sees the right. To do this we will use red/blue 3D glasses and when viewed through the glasses, our photo will appear three-dimensional!
Materials
- Digital camera
- Photo editing software (Such as Adobe Photoshop)
- Red/blue 3D glasses (You can make your own or buy them)
Hints
- Don't save the changes to the original photos, always work with a copy.
- Try making other versions and centering on something else in your photo (something more in the foreground or background) than what you originally planned.
- It may be helpful to adjust the alignment while watching through 3D glasses.
- This method works especially well with close up photos of detailed and textured things (use your camera's macro mode, usually indicated with an icon of a flower which will make it auto focus even when very close to your subject).
Activity Procedures
- Start out by picking a subject. It is easier to take photos of objects or landscapes because we need to take two photos that are as identical as possible. Shots of people can work provided they stay very still and do not move in the time it takes you to snap two photos. Take your first photo, then try to slide the camera over 3 inches and take the same photo again. One easy trick is to take one photo looking through your left eye and the second while looking through your right. A common mistake is to take the pictures too far apart.
- Download the photos to your computer and open them up in a photo-editing software such as Adobe Photoshop. Any program will work as long as it allows for red, blue, and green color channels to be manipulated independently.
- Once both pictures are open, convert them both to grayscale by clicking on IMAGE in the menu bar and selecting MODE then GRAYSCALE. [Image>Mode>Grayscale]
- Convert the right photo back to red, green, and blue (RGB) by clicking IMAGE on the menu bar and selecting MODE then RGB (the image will still appear gray). [Image>Mode>RGB]
- In the Channels tab (in the layers palette between the LAYERS and PATHS tabs), select the red channel by clicking on the word RED - NOT the little eye next to it (eyes indicate which channels are displayed, not selected). Only that channel should appear highlighted.
- Go back to the left photo and select the entire photo [Ctrl-A] for PC or [Command-A] for MAC then copy the image [Ctrl-C] for PC or [Command-C] for MAC, and finally return to the right photo and paste the image [Ctrl-V] for PC or [Command-V] for MAC.
- Now you are ready to complete the merging of the left and right images. Go back to the channels palette. Click on the little box next to RBG. An eye should appear in all four channels but still only the red channel is highlighted. You should now have a mostly black and white image with red and blue halos.
- You are nearly done. The left and right eye images need to be better aligned to remove as many of the halos as possible. This is achieved by centering the two images on the subject of your photo (typically what is in front and center - this will be the easiest part of the 3D photo for peple to focus on). Select the move tool [press V] then use the arrow keys to move the red image until you see the best alignment. We are trying to remove the halos from around our subject, though objects towards the edges will still be quite haloed.
- The final step is to crop the image down to the size you want using the crop tool located in the tool bar (left hand column, third tool down). Try to remove areas of excess red or blue around the edges. Once you have selected the area of the image you want to keep hit ENTER to crop the image. Now that you are done, don't forget to save!
- Now when you look at your image using red/blue 3D glasses you should see the scene appear in 3D, depending on which way your shifted the images you might need to switch which way you are looking through the glasses. You should try experimenting for a while with taking photos and creating the images to get the best results.
I bet Nike ZoomX Vaporfly Next%, the 3D printed marathon shoes, must've motivated you to build something cool. It's only wise that you would want to try a 3D printing software before investing in a 3D printer. However, choosing a good free 3D printing software can prove to be a hassle. There are too many options where each caters to a diverse range of applications.
To make things a bit simpler, we've compiled a list of the best 3D printing software for beginners. But before we take a look at the list, there's one thing you should know. If you're already using Photoshop, then you can get started right away. Photoshop also lets you create 3D models from scratch and print them using services like Shapeways 3D.

Kicking off the list is TinkerCAD, an online 3D design application which is perfect for beginners. It makes use of a simple block building concept, which essentially gives you access to basic shapes using which you can make your 3D models. That makes it an excellent tool for creating geometric designs.
TinkerCAD is fairly simple to get familiar with, and it also offers a bunch of amazing tutorials to speed up the learning process. Once you're done making a model, it lets you share or export the file easily.
And if you don't own a 3D printer, you can also make use of its third-party printing service integration to get your model delivered to your doorstep in no time.
Try TinkerCAD2. Cura
Next up is Cura, another great 3D printing application for beginners from Ultimaker, a leading manufacturer of 3D printers. Unlike TinkerCAD, Cura is a slicing software for 3D printers which you can use to create a 3D model and slice it into layers as G-Code for the printer.
On top of that, you can also use Cura as a failsafe measure for your models. It can let you know if there are any problems with your model's structure that might cause issues with the printing.
That feature is a blessing for beginners since it ensures that you don't waste any printing material or time on creating models with structural issues.
Try Cura3. Sculptris
While TinkerCAD is great for creating geometric designs, you should give Sculptris a shot if you want to create something a bit more organic. It's quite simple to use and offers a few key features that will help you create stunning 3D sculptures.
Working on Sculptris feels a lot like working with modeling clay, which makes it one of the best options if you're looking to create 3D models of things like cartoon characters; something that you can't do with TinkerCAD.
However, you'll only be able to create very basic 3D sculptures with Sculptris. You'll need to rely on other premium software like ZBrush to refine your designs later. Apple operating system download for laptop.
Try Sculptris4. SketchUp
If 3D sculpting isn't really your cup of tea and you'd much prefer software that relies on line drawings to help you create a 3D model, then you should try using SketchUp. The software is suitable for most skill levels as it has a natural learning curve. And once you get going, the software offers a couple of advanced features as well in the paid version.
Much like TinkerCAD, SketchUp is useful for creating geometric designs. The software is most commonly used for designing architectural projects. So if that's what you're aiming for, then you just can't go wrong with it.
The best part about using SketchUP is that it's also available as a web app. You can work on your design on any system as long as you have it saved on your account.
Try SketchUp5. Meshmixer
Meshmixer is another viable option if you're going to be sculpting organic models in 3D as it makes use of a triangular mesh to help you create smooth, even surfaces.
Will premiere pro run on macbook air. Just like Cura, the software also includes a feature which will help you check your model for holes and fix them in real-time.
Along with that, Meshmixer is also great for preparing your designs for 3D printing. It includes tools to slice the sculpture for the 3D printer, generate supports for structural integrity and even analyzes the design's fragility before you send it over for printing.
Try MeshMixer6. 3D Slash
Now if you're aiming for a retro, blocky aesthetic for your 3D models, then you should check out 3D Slash. The software allows you to upload your 3D model which it then breaks down into 3D building blocks.
You can then make any changes to the model using a variety of different tools. However, you will face some limitations in terms of functions in the free version of the software.
Along with the ability to pixelate just about any model, 3D Slash also offers a VR mode. You can use that mode to get a clear view of how your model will turn out using a VR headset. 3D Slash comes with one of the simplest user interfaces out of all the software on this list. That's what makes it a fantastic option for people of all ages.
Try 3D Slash7. FreeCAD
Software To Make 3d Images
Rounding things off is FreeCAD, a parametric 3D modeling tool which will help you create precise geometric designs like replacement parts for your gadgets. The software isn't as good for creating new designs as it is for altering existing ones because of its parametric component.
Editing existing designs is fairly simple; you just need to head to your model history and change the parameters. It's that simple.
So if you're not hell-bent on creating your 3D models from scratch, then you should try FreeCAD. However, if you'd much rather create your custom model, then you'd be better off with either of the other options.
