Trans4motor is a simulator where you can control the movements of single cylinder to 12 cylinder 4 stroke engines on the iPad/iPhone. Recommended to anyone interested in car and motorcycle engines. This is for those who have a relentless love for engines and want to enhance their knowledge. #3 Top Paid iPad App in Japan #5 Top Paid iPhone App in Japan https://www.youtube.com/user/Trans4motor https://www.facebook.com/Trans4motor Features 1) Seamlessly transforms into different type of engines Select from inline to V-type, or other multi-cylinder engines, and watch the running engines transform over continuous CG animation. Enjoy watching the inline engine camshaft separate into two parts as it transforms into the V-type engine and how phase angle modulation between cylinders makes the crankshaft rotate, separate, and combine into many engine formations. 2) Add Engine Sound (In-App Purchase) Developed in technical collaboration with "CAI MEDIA CO.,LTD.", the developer of the iPhone app featuring innovative synthetic engine sound, "RealEngineSim" this new feature will add a variety of realistic engine sounds ranging from different number of cylinders to explosions with unequal intervals and cylinder rest. Engine Sound Add-On is available via In-App Purchase. 3) Accelerator Control Accelerator control is available during engine sound replay. Tilt iPhone to different degrees as if pressing the accelerator pedal. Tilt forward horizontally (as if pressing the accelerator) to activate the accelerator, and erect vertically (as if releasing the accelerator) to deactivate it. Furthermore, you can race the engine by tapping the center of rev counter. 4) Addition/expansion of engines There are currently 22 types of engines registered. Through automatic network updates, continuous expansion is planned. In addition, there are functions installed that allow users to newly register and edit engines. Able to adjust setting for engine bore stroke, firing order, and ignition timing. Easily replicate on the iPad, engines with unequal combustion intervals for two-wheelers, Inline-four crossplane or V5. 5) Interactive Movie ·Four-stroke engines ·Firing Order ·V Angle Recorded 3 controllable presentation videos. The company and product names used within the application are generally registered trademarks or trademarks of the respective companies. The objective of this application is to upload engine specifications disclosed to the public and to learn about general information regarding engines. It does not accurately replicate actual machine measurements and designs. The CG animated engine rotates at one tenth of the actual speed to enable users to learn the structure and to enjoy the visual.

Note: This application is to test the features and capabilities of ARKit. In the era of a computer replacing books, innovative technologies like augmented reality pave way for the fun, attractive and exciting way of education. Engine Visualization an AR application is a new form of Augmented reality application that offers users to visualize an engine in the real world along with its functions. The user will be able to view the engine in detail from all sides, and also figure out the features of different tunings. Engine Visualization AR is compatible with ARCore Supported devices. Please check the below link to find out if your device is ARcore compatible. https://developers.google.com/ar/discover/supported-devices Sharing information with augmented reality is fun and exciting. The user has to point the camera on to a flat surface through the application. Once the application detects enough feature points the engine will come to life through your phone. This showcase application enables the users to visualize the engine in the real world on the go, regardless of their location. The options to scale, position and rotate make it more interactive and easier to view the inner parts and how they function. The easy to access UI makes it more user-friendly. Features: The scale, position and rotation features make this application more interactable The User at any point can zoom rotate or position the engine to have a detailed look. 3D animations: The real-life animation of the engine helps the user to understand the functionality of the function and simultaneously educate himself without the hassle of going to a mechanic shop or an automobile exhibition. X-ray View: The X-ray view allows the user to have a detailed view of the interior parts of the engine and their functionality High-quality 3D models: The 3D model of the engine is very similar to the real-life engine which helps the user easily relate to the real-life engine and its function. RPM Control: The RPM of the Engine can be controlled using the slider and on adjusting the slider, the engine’s RPM will be changed and also changes the sound of the running engine Audio Integration: The engine now has audio which replicates the real-life engine sound and the sound can be controlled by changing the RPM. The mute button is also provided to turn off the sound Effects Non-AR: All the features from AR are supported in Non-AR mode as well. Voice Assistance: Each 3D parts in the engine are interactable. On interacting with the parts in the Engine it highlights the part clicked and declares it out so that it helps the user on how to pronounce them. Engine Visualization is totally free to play and no ads are supported for now Upcoming Features: - More Interactions Contact us on for AR/VR related queries and development support Gmail - admin@devdensolutions.com Follow us on Web - www.devdensolutions.com Facebook- https://www.facebook.com/devdencreativesolutions/ Instagram- https://www.instagram.com/devden_creative/ Youtube- https://www.youtube.com/channel/UCl0z5GurtgyND9yRWMpq9Cg Linkedin- https://www.linkedin.com/company/14433245/admin/ For testing purpose only.
