## What is ARPlanar?

ARPlanar,
A different way to measure the environment!

The app has its own plane detection algorithm, capable of detecting and merging planes at a speed of 200 frames per second, including the vertex colors.
The precision is around 5 centimeters, and it can be configured in the app.

You can compare planes to see what's their distance and their normal orientation in Euler angles.
It is possible to obtain room approximate area by selecting 4 planes.

Every scene can be saved into a binary file using Menu -> Model -> Save.
Then the scene can be loaded anytime for inspection in AR or 3D mode using Menu -> Model -> Load.

It is also possible to export to OBJ files (colors are not included), or ASCII PLY (including colors).
The user can share the scene or the recording through AirDrop or see them to Files app.

The app is based on my previous work on my thesis diploma:
 - find all the dominant planes in a point cloud
 - merge similar planes into a global map
 - measure distances from one plane to the other
 - approximate the relative rotation and translation from one pose to the other

Features:
 - plane segmentation
 - plane merging in auto mode and manual mode
 - project the plane points to the plane
 - find distances by averaging the distance from the center of one plane to another
 - export the map with their projected points or not
 - load previously exported scenes and view them in AR or 3D
 - record point clouds together with camera poses into binary files and replay them later

Enjoy.

## Key features

- Plane detection and merging
- Distance and area measurement

### 5/5 — Good work!

*2024-03-21*

I don’t know how to use this for work based purposes, but I see the app is well made and does what it is supposed to. It’s cool I can use this on my phone, and you’ve made it free! Thank you. Well done.

### 5/5 — Great app and huge potential

*2023-09-25, version 1.9*

I used it today and the level of detail is incredible. The distance measurement feature is very accurate and the scanning process is intuitive. I need *.pts or *.las format or even better a *.dxf file for any selected height section plane (or even vertical planes). But I guess I’ll have to do the conversion elsewhere. 

Great job.

### 1/5 — Un horror

*2021-02-06, version 1.3*

Mala no lo siguiente.

## Frequently asked questions about ARPlanar

### What is ARPlanar's precision?

ARPlanar offers a precision of around 5 centimeters, which can be configured within the app settings. This allows for detailed and accurate environmental measurements.

### Can I calculate room area with ARPlanar?

Yes, you can obtain an approximate room area by selecting four planes within the app. This feature is useful for quick estimations of space.

### What export formats does ARPlanar support?

ARPlanar supports exporting scenes to OBJ files (without colors) and ASCII PLY files (including colors). This allows for integration with other 3D modeling software.

### How do I save and load scenes in ARPlanar?

Scenes can be saved into a binary file via the 'Menu -> Model -> Save' option. Later, you can load these scenes for inspection in AR or 3D mode using 'Menu -> Model -> Load'.

### Does ARPlanar have ads?

No, ARPlanar does not contain advertisements. It is a completely ad-free application, providing an uninterrupted user experience.

### What devices is ARPlanar compatible with?

ARPlanar is compatible with iPhone, iPad, and iPod devices. It is designed to leverage the augmented reality capabilities of these Apple devices.

### How often is ARPlanar updated?

The latest version of ARPlanar is 1.9, last updated on April 1, 2023. This indicates a relatively consistent update schedule for the application.

### What is the age rating for ARPlanar?

ARPlanar has an age rating of 4+, making it suitable for a wide range of users. This rating suggests that the content is appropriate for young children.

## Version history (last 5 releases)

### 1.9 — 2023-04-01

Split planes into small regions that are rendered using textures (TriTex)

### 1.8 — 2022-01-15

Fix font atlas

### 1.7 — 2021-03-10

Added record button
Added inches and feed measurement units

### 1.6 — 2021-02-25

Dislplay line segment length created by all selected plane intersections

### 1.5 — 2021-02-21

Display distance (depth) of the center point.
Display segment length of the detected floor polygons. Small polygons are discarded. This can be adjusted using Draw->min_poly_area. Its default value is 2 squared meters.
Display height plane differences for vertical and horizontal planes. Floor level is considered the lowest AABB of all selected planes.
Many other fixes and improvements.
