[iPhone12 Pro / iPadPro 2020] Using Forge to create a 3D model scene

In this article, I will show you a series of steps to create a 3D model scene using Forge, a mesh scanning application for iOS released by Abound Labs Inc.

What is Forge?

Forge is an app that allows you to create a 3D model scene using the LiDAR (3D scanning function) that is available on the latest iOS devices mentioned above.
It can be used on Apple devices equipped with LiDAR, and features an easy-to-use user interface.
There are many other scanner apps that allow you to easily create 3D model spaces today, such as the “3d Scanner App” and “Scandy Pro” that allows you to accurately create face models using the face recognition function.

Forge specializes in spatial generation, and has become a hot topic on social networking sites for its extremely low error rate compared to reality caused by scanning.
I’ll be showing you a series of steps to actually create a 3D model space using Forge and upload it to STYLY.

The app also has a chargeable component, and if you pay a monthly fee, you can export in FBX or OBJ format.
Please refer to the following LiDAR app comparison chart created by a person named imawa@h, which includes a comparison with other apps and their merits.

First of all, let’s do some preliminary preparations.
The following iOS devices are compatible with Forge.

  • iPad Pro (2020)
  • iPhone12 Pro
  • iPhone12 Pro Max

Next, let’s download Forge.

Using Forge to create a 3D model scene

We will be using an iPad Pro (2020) to take pictures.
We will take pictures of a road and turn it into a 3D model scene.
First, let’s start Forge.

My Scans screen

My Scans screen

When you open Forge, you will see a screen called “My Scans”.
This is where you will manage the data you have taken.
Now let’s start shooting. Press the “+” mark in the lower right corner.

This will take you to the shooting screen.
One of the features of Forge is that it has various functions such as zooming while shooting and making the subject monochrome to make it easier to shoot.
Let me introduce the functions one by one.

  • Color
    This function allows you to make the subject monochrome and then colorize the area of the subject that is being scanned, or conversely, display the scanned area as achromatic polygons.
  • Camera
    Allows you to zoom in on your subject.
  • Follow
    Displays the scanned subject in virtual space.
  • Above
    Focuses on the ground and tracks the photographer’s movements to make it easier to shoot.

I turned on Color for shooting.
I felt that one of the features of Forge is the ability to use different functions depending on the shooting location and situation.

At first, I recommend shooting a small area.
As is the case with other apps, if you shoot a wide area, there is a risk that the app will crash and the data will be lost when exporting, so start by shooting a small area and gradually expand it.
As shown in the image, you can create a beautiful image by carefully shooting around colored cones and rounded objects.

Press the Stop button.

Press the Stop button.

When you are done shooting, press the red rectangle to end the shooting.
Exporting will begin. While exporting, the texture will be unclear, but when it is finished, it will be displayed beautifully.
When the export is finished, take a look at the 3D model to check it.

Exporting with FBX

Exporting with FBX

The next step is to export the 3D model to send it to your PC.
Tap the Share button below and select FBX.
I use Google Drive, so I uploaded the file to Google Drive that comes up afterwards.
This completes the process using your iPad/iPhone.

Uploading to STYLY

You can learn more about how to upload a 3D model scene in following article.

How was it? By scanning an actual space and turning it into a 3D model space, it can be useful as a material for production or as a work of art.
Please refer to this article and try to make a 3D model of your space.
