3D Scan your Environment with AI (Free Tool)
TLDRIn this tutorial, the presenter demonstrates how to create NeRF (Neural Radiance Fields) scans using Luma AI, a free tool that employs artificial intelligence to scan environments and produce stunning camera animations. Unlike traditional photogrammetry, NeRF can capture metallic and reflective surfaces. The process begins by recording a video of the subject using a smartphone, moving around it in circles to capture various angles and heights. After uploading the video to Luma Labs, the scan is processed, and the user can view and manipulate it in a 3D viewport. The presenter then guides viewers through creating a camera animation by setting keyframes and adjusting the focal length for different perspectives. The animation can be customized or generated using preset camera animations. Finally, the video is rendered in the desired aspect ratio and resolution, with the option to use custom or preset camera paths. The presenter also offers a free download of the 3D assets used in the tutorial.
Takeaways
- 🎥 **Using Luma AI for NeRF Scans**: The video demonstrates how to create NeRF (Neural Radiance Fields) scans using a free tool called Luma AI.
- 📱 **Equipment Needed**: You don't need an expensive camera to create NeRF scans; an iPhone can be used for recording.
- 🔄 **Capturing the Subject**: To scan, move around the subject in circles at least three times, varying heights to capture different perspectives.
- ⏸️ **Tips from Luma AI**: There are specific tips provided by Luma AI to pause and read before capturing the video.
- đź“Š **Uploading and Processing**: After recording, upload the video to Luma Labs to start the scanning process, which takes around 30 minutes.
- đź‘€ **3D Viewport**: Once the scan is done, you can view it from various angles in the 3D viewport.
- đź“ą **Camera Animation**: To export as a video, create a camera animation by setting focal length and adding keyframes for the desired camera path.
- ⏳ **Adjusting Animation Speed**: If the animation is too fast, you can extend the duration of keyframes to slow it down.
- 🖥️ **Rendering the Video**: Choose the aspect ratio, resolution, and frame rate for the final video and render it.
- 🚀 **Pre-set Camera Animations**: For convenience, use pre-set camera animations like 'orbit' or 'oscillate' for quick camera movement.
- đź“š **Further Learning**: The creator, Nick, encourages viewers to ask questions in the comments and offers free 3D assets on his Blender Kit profile.
Q & A
What does the term 'NeRF' stand for in the context of the video?
-NeRF stands for Neural Radiance Fields, which is a method used to scan environments and create camera animations.
What is the main advantage of using Luma AI for scanning compared to traditional photogrammetry?
-Luma AI utilizes artificial intelligence, allowing the capture of metallic and reflective surfaces, which can be challenging with traditional photogrammetry.
What device did the presenter use to record the video for the NeRF scan?
-The presenter used an iPhone to record the video for the NeRF scan.
How many times should one move around the subject when recording the video?
-One should move around the subject at least three times to cover different perspectives.
What is the approximate time it takes for the scan to be processed on Luma labs servers?
-The scan usually takes around 30 minutes to be processed on Luma labs servers.
How can one view the 3D scan after it has been processed?
-After the scan is processed, one can view it in the 3D viewport on Luma labs.
What is the first step in creating a camera animation for the NeRF scan?
-The first step is to set the focal length of the camera by adjusting the value to desired zoom level.
How does one add a key frame to the camera animation?
-To add a key frame, place the camera where you want to start, click the 'add key frame' button, then move the camera to the next desired position and add another key frame.
What can be done to make the camera animation longer?
-To make the animation longer, one can extend the duration of the key frames on the timeline by dragging them to increase the time.
What are the options for rendering the video?
-One can choose the aspect ratio, set a custom one, select the resolution (e.g., full HD), and set the frame rate (e.g., 30 FPS) before rendering.
How can one use preset camera animations in Luma AI?
-One can go to 'trajectories' and choose from presets like 'orbit' for a rotating camera or 'oscillate' for a camera with a bit of movement.
Where can viewers find the 3D assets created in the video?
-The 3D assets can be downloaded for free from the presenter's Blender Kit profile, with the link provided in the video description.

🎥 Introduction to Creating Nerf Scans with Luma AI
The video tutorial begins with a welcome back message and an introduction to the process of creating Nerf (Neural Radiance Fields) scans using Luma AI, a free tool. The host explains that Nerf scanning is a novel method for scanning environments to produce impressive camera animations. Unlike traditional photogrammetry, it leverages AI to capture metallic and reflective surfaces. The host shares their recent work using this technique for a client and instructs viewers to record a video of the subject using any camera, emphasizing that an expensive one is not necessary. The video recording should involve circling the subject three times at varying heights to capture it from multiple perspectives. The host also advises pausing the video to read tips from Luma AI before starting to capture.
