view3dscene vs. Fast STL Viewer

view3dscene is a highly adaptable viewer that supports an extensive range of 3D model formats, such as glTF, X3D, VRML, Collada, 3DS, MD3, Wavefront OBJ, and STL, along with 2D formats including Spine JSON and sprite sheets from CGE, Cocos2d, and Starling XML. Users can explore a dynamic virtual environment enriched with features like collisions, gravity, animations, sensors, shadows, mirrors, shaders, and more. In addition to its viewing capabilities, it can effortlessly convert all models into the X3D format, streamlining the workflow for developers. If you have the Castle Game Engine, executing view3dscene from the CGE bin subdirectory is a straightforward process without any additional downloads required. All supported model formats by the Castle Game Engine, including X3D, VRML, Collada, 3DS, MD3, Wavefront OBJ, and Spine JSON, are readily accessible. The application boasts various navigation methods such as examine, which allows users to rotate and reposition the entire model; walk, simulating first-person shooter movements with collision detection and gravity; fly, which resembles walk mode but without gravitational constraints; and 2D navigation. Moreover, users can easily convert between X3D classic and XML encodings in either direction, along with transitioning from VRML 2 to X3D, further enhancing the versatility of model management. Consequently, view3dscene stands out as an indispensable resource for developers and artists engaged with both 3D and 2D model formats across diverse development platforms.

The application is capable of handling both binary and ASCII STL file formats, enabling users to visualize 3D models directly on their Android devices. It supports the simultaneous viewing of multiple files and models, offering various practical modes such as shaded, wireframe, a hybrid of both, and point views. To improve visibility, distinct colors are employed to differentiate between the front and back sides of the models. Users can enjoy swift loading times for STL files, even those containing millions of triangles, allowing for efficient management of larger models. Key features include boundary detection and the ability to recognize separate networks or components within a model. Interaction is made easy, as users can select a model by tapping on it and can deselect by touching the background. The status display shows bounding box details when a model is selected, and users have the flexibility to invert normals or remove a chosen model from the scene. Moreover, the app facilitates direct access to STL files from various cloud storage services, including Gmail attachments, Google Drive, Dropbox, and OneDrive through Fast STL Viewer. For users interested in 3D printing, there is an integrated option to connect with Treatstock, while the internal file manager conveniently tracks the last ten accessed files for quick retrieval. Additionally, the application is designed to provide a user-friendly experience, ensuring that both casual users and professionals have a comprehensive toolkit for STL file management and visualization.
