Harmonic Wave Equation Calculator is a physics/math calculator used to find the displacement of a given point along the wave, the position of that point, the time point, wave velocity, wavelength, amplitude, or initial phase of the wave quickly and easily. Features: - Instant calculation. - Results are copyable to other apps. - Formulas are included as references. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. A harmonic of such a wave is a wave with a frequency that is a positive integer multiple of the frequency of the original wave, known as the fundamental frequency. The original wave is also called the 1st harmonic; the following harmonics are known as higher harmonics. Formula: y = A * sin[(2π / λ) * (x - vt) + Φ] where: y - displacement of a given point along the wave x - position of that point (its distance from the source) t - time point v - wave velocity λ - wavelength A - amplitude Φ - initial phase of the wave Thank you for your support, and feel free to visit nitrio.com for more apps for your iOS devices.

Scanning and exporting data utilizing Sakura3D SCAN can come in handy for various fields. For example, plants can acquire the current status of pipes and other factory equipment, while construction and civil engineering firms can utilize Sakura3D SCAN in topographical surveys and construction progress management. Import your scanned data into our point cloud modeling software "ClassNK-PEERLESS" and create 3D models that can be imported into various CAD systems. ■ Export format Point cloud: ASC, TXT, PTS Mesh: OBJ, STL ■ Sakura3D SCAN requires the LiDAR sensor for scanning, as a result we only support the following devices iPhone 18 Pro Max iPhone 18 Pro iPhone 17 Pro Max iPhone 17 Pro iPhone 16 Pro Max iPhone 16 Pro iPhone 15 Pro Max iPhone 15 Pro iPhone 14 Pro Max iPhone 14 Pro iPhone 13 Pro Max iPhone 13 Pro iPhone 12 Pro Max iPhone 12 Pro iPad Pro 13 inch (M4) iPad Pro 11 inch (M4) iPad Pro 12.9 inch (6th generation) iPad Pro 11 inch (4th generation) iPad Pro 12.9 inch (5th generation) iPad Pro 11 inch (3rd generation) iPad Pro 12.9 inch (4th generation) iPad Pro 11 inch (2nd generation) ■ Difference between a free plan and subscriptions All features are available for free, except for file output and certain premium features (e.g., Center of Gravity Visualization). By subscribing, you can enjoy unlimited file exports and gain full access to all premium features. File export is also free under following conditions. ・Point cloud: less than 500K points ・Mesh: less than 50K vertices ・Unlimited export: Once every 24h With a subscription, there is no limit to the number of scans you can export. ■ FAQ ・ How can I increase the quality of my scans? When measuring please try to move slowly and avoid shaking the device. Please try to avoid measuring the same location twice. The trick is not to scan the same point over and over again. The following are some of the factors that can hinder a good scan: - When the object is a transparent object made of glass, a shiny metal object, a mirror, etc. - When the distance to the object to be scanned is too short (within 10 to 20 cm) ・I don't know which scan accuracy to use. Scan accuracy depends on the scan target, scan environment, and setting method. For a personalized inquiry please send an email to sakura3d@armonicos.co.jp with your target, environment and setting method. ・What distance allows for an accurate measurement? The recommended distance is within 5m. ・How many points can be obtained in each scan? You can get up to 25 million points. ・Is it possible to check the number of points during a scan? The number of acquired points is displayed on the screen, during a scan, with the following color encoding as a guideline for memory usage: "green (low)-> yellow (medium)-> red (high)" . ・I don't know how to export data. There are two methods, one is via the Internet using Dropbox, AirDrop, email, various SNS, or Google Drive, and the other is to connect the device (iPhone, iPad) directly to the PC with a cable and copy the data using iTunes. ・Can the output data be imported into other software? Data created with Sakura3D SCAN can be imported into any software that supports point cloud formats (ASC, TXT,PTS) or mesh formats (STL, OBJ). It can also be imported into our software packages: spGate, spGauge, spScan, and ClassNK-PEERLESS. Sakura3D SCAN Terms of Service (ToS) https://www.armonicos.co.jp/shop/sakura-tos/
