• Furnish with AR: This app essentially functions as an app to see furniture in your room using AR technology. Pick an item from the extensive IKEA 3D catalog, then use your phone’s camera to virtually place that sofa, table or bed into your actual room and view it at true scale. You can walk around and see how the piece looks from different angles, just as if it were really there.

It’s a comprehensive way to visualize interior design changes – from the big furniture down to accent pieces.
• Real-time 3D view: Besides the AR mode using your camera, Room Planner offers a standard 3D design view on your device. This lets you move around a fully virtual rendition of your planned room to ensure everything fits and looks great from every perspective.

These features give you fine control similar to professional CAD software, which is excellent for 3D interior design rendering tasks that require detail.
• High-quality rendering: Adjust environmental lighting (time of day, geographic location for sunlight) and add light sources to lamps to simulate realistic lighting in your model. Live Home 3D’s rendering engine produces very detailed images with reflections, shadows, and textures that look true-to-life. You can capture static images, create 360° panorama views, or even record a video walkthrough of your virtual space to share with others.
• AR and mobile visualization: On iPhone and iPad, Live Home 3D has a fantastic augmented reality feature – you can project your designed room or house at full scale onto your real-world surroundings via your device’s camera. Walk through your design as if it were built, using AR to see how furniture and layouts would feel in actual size.

Lighting, shadows, reflections, and materials are automatically optimized to look realistic.
