Hello everyone, I had the privilege of dedicating a week to thoroughly testing the Miraco. With over two decades of experience in the film and TV industry and a solid 15 years of working with 3D scanners, I’ve accumulated an assortment of scanning tools over the years, including my trusty old NextEngine desktop scanner, a Revopoint POP, a Range, and the latest addition, a Miraco. Additionally, I’ve extensively delved into the world of photogrammetry. Recently, I decided to step out of my film and VFX domain and published a video on YouTube, aiming to put the scanner through its paces directly in front of the camera. [![](https://canada1.discourse-cdn.com/flex029/uploads/revopoint3d/original/2X/1/1d8d2d6fb2fa5dfbc79a8deafd5971ac96334c8b.jpeg "Revopoint Miraco 3D Scanner complete test") ](https://www.youtube.com/watch?v=LTT1ZEq5s8g) I want to emphasize that I don’t belong to the usual YouTube content creator category. My main expertise lies within the film and visual effects industry, so please understand if I seem a bit out of my comfort zone in front of the camera 😉 Should you have any questions or require further insights, please don’t hesitate to reach out. Thank you for your time and consideration. Link to the kickstarter page of the Revopoint Miraco: [https://revo.ink/3Fkkk9k](https://revo.ink/3Fkkk9k) Warm regards, Julien ---

Hi @Giu3232 Thank you for sharing and creating! You look great in the video. Hope to see more of your MIRACO sharing! 😊 ---

Thank you, that’s a great review! Very good comparison between far and near mode. Also the fact, that your background is vfx industry helps for people like me who are more interested in the visual quality of the scans. I would really like to know more about your opinion on the texture quality. Would it be possible to do a test scan also in far and near mode from a medium sized object with texture on? ---

> [@KRS](#): > > Would it be possible to do a test scan also in far and near mode from a medium sized object with texture on? Hi @KRS the early MIRACO Beta prototype versions that most reviewers got was not fully ready for capturing color textures in its full potential. For that reason I would advice to not suggest yourself with the color results yet as that are not the final product quality results, as not all features was added yet to the beta devices . I will have soon full color MIRACO Showcase … stay tuned ---

Thank you for your reply! I am eagerly waiting for your showcase. I also have an additional request. As i haven’t been able to find any downloadable sample scan from the Miraco it would be very helpfull if you could make this textured 3D scan available for download. It would be even better, if the corresponding project file to open with revo scan was also available for download. Thank you so much for your help! ---

> [@KRS](#): > > It would be even better, if the corresponding project file to open with revo scan was also available for download. Since the campaign is not finished yet or the final Miraco in final production , sharing data from beta devices is not permitted yet under NDA restrictions… I understand that you would love to check on the progress but without permission I can’t do that , neither anybody else . I will see what I can do , if the results meet the satisfactory of the dev.team …maybe I will be allowed to do that . For some of my work color scans are also very important … and things getting better and better so fingers crossed 🤞 ---

Hello, As I mentioned in the video, my needs are a bit specific since the film industry has specific texture requirements. Typically, we employ a polarized filter on the camera and position two light sources at 45-degree angles on either side of the objects, also using polarized lighting. This setup, known as “crossed polarized,” effectively eliminates 100% of reflections. I’m not entirely certain how well the Miraco scanner would accommodate this setup. Specially if the technology is based on light to capture the geometry. Furthermore, we need the capability to manipulate shadows and highlights effectively, which is why we shoot in RAW format with a minimum of 16 bits to ensure the utmost flexibility in post-production. It may change but the current textures seems to be 8bits .jpg only There are two methods for processing textures: utilizing pictures taken during the scan of each frame and assigning a color value to each face. Textures provide higher resolution, but during my tests, I found that vertex color appeared more accurate. I maintain regular communication with the team regarding texture-related matters. I want to clarify that I am not affiliated with Revopoint, so I may not have information on the distinctions between the beta version of the scanner I have and the final product. However, based on @PUTV answers, it seems that my unit is likely an early developmental version. From what I understand, and a moderator can correct me if I’m mistaken, the scanner employs a technique similar to laser scanning. It scans one patch, capturing associated images, then proceeds to the next frame, repeating the process iteratively. Once it has collected all the point cloud data and images, it consolidates them into a single mesh and a unified texture. However, while the geometry fusion is remarkably precise and consistent, merging textures can present challenges. The geometry remains consistent, but the color quality is highly contingent on factors like reflections, camera settings, and the object’s position relative to light sources. During testing, I occasionally noticed visible seams between the pictures taken, which is why I primarily opted for the vertex mode rather than relying on texture color. If the final version of the scanner addresses these texture issues and introduces the ability to export 16-bit TIFF or possibly 32-bit .exr files, the Miraco could potentially reach a level suitable for professional production use in geometry AND texturing. Once this is achieved, I might primarily use photogrammetry only for capturing entire environmental scenes, and use the Miraco for everything else. To sum it up, my encounter with the scanner left me thoroughly impressed, and I was pleasantly taken aback by its capabilities. With the exception of the texture-related challenges (which might be attributed to my unit being an early beta version), this device stands out as a truly remarkable piece of technology. ---

HI @Giu3232 MIRACO uses 3D structured light technology . The light source ( infrared ) from the scanner head projector projects a series of parallel patterns onto the scanned target and measure the three-dimensional shape. When infrared light projects the patterns onto the object’s surface, the patterns become distorted. The cameras capture these images and send them to the software for processing as a Raw unorganized frame cells , after that the fusing process organize it into regular point cloud that can be later meshed . ---
