3D Scan your Environment with AI (Free Tool)
TLDRThis tutorial introduces Luma AI, a free tool for creating 3D NeRF scans of environments. NeRF, or Neural Radiance Fields, is a novel method that uses AI to capture even metallic and reflective surfaces. The video demonstrates recording a subject with a simple camera, uploading the footage to Luma Labs for processing, and then creating and animating a camera path to render a smooth and engaging 3D animation. Tips for capturing the video and custom camera animations are provided, along with shortcuts using preset trajectories. The creator also offers free 3D assets from the tutorial on their Blender kit profile.

- 📱 You can use a smartphone, like an iPhone, to record a video of the subject for scanning without needing an expensive camera.
- 🔄 Move around the subject in circles at least three times, capturing different heights for a comprehensive scan.
- 👀 Luma AI can handle metallic and reflective surfaces, which is a difference from traditional photogrammetry methods.
- 📹 After recording, upload the video to Luma Labs to start the scanning process, which takes approximately 30 minutes.
- 🎨 The scan can be viewed from various angles in the 3D viewport, showcasing the detailed outcome of the NeRF scan.
- 📹 To create a camera animation, set the focal length and add key frames to define the camera's movement.
- ⏱ Adjust the duration of the animation by manipulating the key frames on the timeline to create a smooth sequence.
- 🎥 Render the video with your choice of aspect ratio, resolution, and frame rate to export the final animation.
- 🔄 Luma AI offers preset camera animations like 'orbit' and 'oscillate' for quick and easy animation setups.
- 💻 The tutorial is provided by Nick, who also offers free 3D assets from his Blender kit for download.

Outlines
📱 Introduction to Creating Nerf Scans with Luma AI
This paragraph introduces a tutorial on how to create Nerf (Neural Radiance Fields) scans using Luma AI, a free tool that employs artificial intelligence to scan environments and create camera animations, including metallic and reflective surfaces. The speaker shares their recent experience using the tool for a client and emphasizes that high-end camera equipment is not necessary, as an iPhone can suffice for capturing the video needed for scanning. The process involves moving around the subject in circles and at different heights to ensure comprehensive coverage from multiple perspectives.
🎥 Tips for Capturing Nerf Scans and Uploading Process
The speaker provides additional tips from Luma AI for capturing Nerf scans, advising viewers to pause the video and read these tips before starting. After recording the video, the user is instructed to upload it to Luma labs' servers to initiate the scanning process. The paragraph explains that the scan processing typically takes about 30 minutes and once completed, the user can view the 3D scan from various angles in the viewport.
🎨 Creating and Customizing Camera Animations
This section describes how to create camera animations for the Nerf scan. The user is guided to set the focal length of the camera to adjust the field of view, from a zoomed-in perspective at 50mm to a wider angle at 15mm. The process of animating involves placing the camera at the desired start point, adding key frames at various positions, and then playing back the animation to review. Adjustments can be made to the speed and duration of the animation by manipulating the key frames on the timeline.
🖥️ Rendering and Exporting the Nerf Animation
The paragraph explains the final steps of rendering and exporting the Nerf animation. The user can choose the aspect ratio and resolution, with options for full HD at 30 FPS. The rendering process is initiated by clicking the 'render' button. Additionally, the tutorial mentions the availability of preset camera animations for those who prefer a quicker approach, with options such as 'orbit' for a looping rotation around the subject or 'oscillate' for a slight movement effect.
📚 Conclusion and Resource Sharing
In conclusion, the speaker expresses satisfaction with the tutorial and encourages viewers to ask questions in the comments section if they have any. They also mention that all 3D assets created during the tutorial are available for free download from the speaker's Blender kit profile, with a link provided in the video description. The tutorial ends with a sign-off from the speaker, Nick, who looks forward to the next video.
