fourth camera” of the new iPhone?

Open “JigSpace”, you can see the clearly classified and rich content of “Jig Library”, in this library, you can select the content of interest to view.

Because of the existence of the lidar scanner, “JigSpace” can be positioned on the plane very quickly, and objects can be placed on the plane with one click.

Through operations such as zooming and dragging, we can view the appearance structure and every detail of three-dimensional objects from multiple angles. At the same time, there is a text description of the corresponding interface below the picture.

Click the arrow on the right side of the screen to enter the analysis interface, and click the corresponding area to display the name of the structure, so that we can have a more comprehensive and in-depth understanding of the AR items displayed.

In addition to the very rich structure display and teaching, “JigSpace” also has a very interesting introduction to scientific principles, from the structure of the traditional lock to the electronic movement of the battery. If you need to explain this knowledge to children, then “JigSpace” is A very convenient and practical teaching tool.

  • Reality Composer: Build your own AR scene

Unlike the previous apps, the “Reality Composer” officially developed by Apple is not an AR application for scanning or teaching aids. With it, you can build an AR scene from scratch.

Open the app, and you will see a recent project interface like when the iWork suite is opened. Click the’+’ in the upper right corner to select the anchored new scene of the AR scene. The editing interface of “Reality Composer” is also similar to iWork. On the left is a scene area with square modules, and on the right is the control area of ​​the model.

As a demonstration, let’s make an AR scene where a ball hits a square mountain. First click on the “+” at the top, add a ball, and select “Steel” in the “Material” on the right, so that we have an iron ball. In the same way, we can also create other objects.

Click the behavior tool in the upper right corner, add the trigger method and trigger result of the sphere, and you can make it move. Here, we can set the speed and direction of the sphere’s movement, and set it to’click to roll forward’.

However, when you click to play, the sphere will pass directly through the block without impact. This is because we have not added a movement type to the block. After setting the movement type of the block to’dynamic’, you can see the animation of the block being knocked open by the sphere.

Next, we copy the square to form a square mountain. Remember, when copying, we must remember to click on the “…” in the upper right corner and select “Copy with behavior”. In this way, the AR scene of the’round ball hitting the square mountain’ that we created has completed the most critical step.

Click the play button in the upper right corner to see how it works.

After creating the scene and animation effect, click the “AR” button at the top to display the newly created AR effect in the real scene.

During the entire production process, we did not perform programming or specifically learned some editing methods, and completed the creation of an AR scene completely through a visual interface. “Reality Composer” also has a very rich model, from shelf cabinets to battery notebooks, from axe brooms to house furniture. If you understand this app in depth, you can create a lot of rich and interesting AR scenes.

Although AR is not new, because of the addition of lidar scanners, AR has higher recognition accuracy and faster speed. Whether it is using AR to try shoes or travel from room to outer space, the new lidar scanner allows AR apps have changed from “available” to “easy to use”.

The potential of the lidar scanner does not stop there. Maybe in the not-too-distant future, we can use it to obtain accurate three-dimensional data of the human body to achieve more perfect fitting and makeup; you can also use the photos and videos obtained Information, rapid realization of 3D modeling, making the production of games and animations easier; even we can create a self exactly like the real world in the virtual world…Perhaps, the lidar scanner can open up a new application system , And this day is not far away.
