What is RoomPlan?
RoomPlan is a framework that helps you to make a 3D model of a room’s interior. It uses an ML model, the device’s sensors, and RealityKit’s rendering functionalities to identify and capture the physical objects of an interior room. Let’s take an example. To recognize walls, windows, entrances, and doors, the framework examines the device’s camera feed and LiDAR readings.
RoomPlan also can identify furniture, and appliances and provides detailed information to the applications.
We Have Used RoomPlan Framework For Our Application
We at Technostacks, a leading mobile app development company, have implemented the RoomPlan framework for our application called Room Planner.
The Room Planner is an interactive and intuitive application that enables you to create, customize, and visualize room layouts in a virtual environment. It enables you to explore various design options, experiment with furniture arrangements, and visualize how diverse components combine to produce a harmonious and purposeful space.
Thus, you can easily enable use cases like previewing a completely virtual space and furniture right from a catalog in a diversity of perfect styles, designs, and positions.

Technostacks Has Successfully Performed Room Planner Implementation For One of Our Clients
At Technostacks, our teams have successfully performed room planner implementation for a client. Let us describes the main view controller of the Room Capture app. The Room Capture app is designed to scan and capture room data using augmented reality (AR) technology.
The view controller manages the scanning process, better processes the captured room data, and provides options to export the captured room data in USDZ format. USDZ format here stands for zip-compressed Universal Scene Description leveraged to transfer rich 3D scenes and models.
To implement Room Planner in the application, first, we need to add camera permission in info.plist file
Dependencies
The Room Capture app uses the following dependencies:
- UIKit: The fundamental framework for building iOS apps.
- RoomPlan: A framework that provides functionality for capturing and processing room data.
- NVActivityIndicatorView: A library for showing loading indicators.
import UIKit import RoomPlan import NVActivityIndicatorView

//Global function get child nodes array
func getChildGroup (arrNode: [SCNNode], name: String) -> [SCNNode]{
let array arrNode. filter term in
return term.name == name
}
return array
}
- StartTapped(_ sender: Any): This method is called when the “Start” button is tapped to initiate customization of the scene. It calls several helper methods to replace objects and add textures to different parts of the scene.
@IBAction func StartTapped(_ sender: Any) {
DispatchQueue.main.async { self.activityIndicatorView.startAnimating()
if let unwrappedNodes = self.sceneView.scene?.rootNode.childNodes[0].childNodes { self.Parametric = self.getChildGroup (arrNode: unwrappedNodes, name: "Parametric_grp")
if self.Parametric.count > 0{
self.objectGroup = self.getChildGroup (arrNode: self.Parametric[0].childNodes, name: "Object_grp")
self. ArchGroup = self.getChildGroup (arrNode: self.Parametric[0].childNodes, name: "Arch_grp") self. Floor_grp = self.getChildGroup (arrNode: self.Parametric[0].childNodes, name: "Floor_grp") if self.objectGroup.count > 0{
self.ChairGroup = self.getChildGroup (arrNode: self.objectGroup[0].childNodes, name: "Chair_grp") self.StorageGroup = self.getChildGroup (arrNode: self.objectGroup[0].childNodes, name: "Storage_grp") self.TableGroup = self.getChildGroup (arrNode: self.objectGroup[0].childNodes, name: "Table_grp") }
{
}
//Replace node or add texture methods
self.ReplaceChair (ChairGroup: self.ChairGroup) {
self.MakeTable (TableGroup: self.TableGroup) {
self.MakeWall (Group: self. ArchGroup) {
self.MakeFloor (Group: self.Floor_grp){
self.MakeStorage (Group: self.StorageGroup) {
DispatchQueue.main.asyncAfter (deadline: .now() + 0.5) self.activityIndicatorView.stopAnimating()
}
print("Done")
} } else {
// Handle the case when the array is nil
}
}
}
//Replace chair with usdz file func ReplaceChair (ChairGroup: [SCNNode], with Completion completion: () -> Void ) {
if ChairGroup.count == 0{
completion()
return
}
for obj in ChairGroup[0].childNodes{
if let objectUrl= Bundle.main.url(forResource: "NewChair", withExtension: "usdz"),
let objectScene = try? SCNScene (url: objectUrl),
let objectNode = objectScene.rootNode.childNodes.first{
var node = objectNode.clone()
node.transform = obj.transform
node.simdPosition = simd_float3(x: obj.simd Position.x, y: -1.5, z: obj.simdPosition.z)
node.scale SCNVector3(x: 0.01, y: 0.01, z: 0.01)
obj.removeFromParentNode()
ChairGroup[0].addChildNode (node)
}
}
completion()
}
//Add texture on table
//Add texture on table
func MakeTable (TableGroup: [SCNNode], withCompletion completion: () -> Void) {
if TableGroup.count == 0{
completion()
return
}
for obj in TableGroup[0].childNodes{
let box = SCNBox (width: 1.0, height: 1.0, length: 0.5, chamferRadius: 0)
let material = SCNMaterial()
let image = UIImage(named: "Table")
material.diffuse.contents = image
box.materials = [material]
obj.geometry box
let node = SCNNode (geometry: box)
}
completion()
}
After the customization, you will get the final output like this:
// exports USDZ and JSON file.
@IBAction func ExportTapped(_ sender: Any) { activityIndicatorView.startAnimating() guard let scene = sceneView.scene else { print("No scene available.")
return
}
do {
// Create a temporary directory to save the exported USDZ file.
let destination FolderURL = FileManager.default.temporaryDirectory.appending (path: "Export")
let destinationURL = destination FolderURL.appending (path: "Room.usdz")
let capturedRoomURL = destination FolderURL.appending (path: "Room.json") scene.write(to: destinationURL, options: nil, delegate: nil, progressHandler: nil) let activityVC = UIActivityViewController (activityItems: [destinationURL], applicationActivities: nil)
activityVC.modal PresentationStyle = .popover present (activityVC, animated: true, completion: nil)
if let popover activityVC. popoverPresentationController { activityIndicatorView.stopAnimating() popOver.sourceView = self.exportButton
}
} catch {
activityIndicatorView.stopAnimating()
print("Error exporting scene as USDZ: \(error.localizedDescription)")
}
}
