CAD Assistant
Open Cascade CAD Assistant is a powerful offline 3D CAD viewer and converter with simple and intuitive interface, free for both personal and commercial use. Originally developed as a testbed and showcase for the Open CASCADE Technology on mobile platforms, the solution has been appreciated as fast and handy 3D viewer by thousands of end-users on mobiles and desktops worldwide. CAD Assistant brings the power of open technologies to the hands of engineers working with 3D data. CAD Assistant is based on open source libraries (Open CASCADE Technology, Qt, FreeType, FreeImage, etc.) and employs open formats for CAD and mesh data (STEP, IFC, IGES, BREP, glTF, JT, PLY, STL, OBJ, 3DM). It also supports a set of other file formats like DXF, SAT (ACIS), XT (Parasolid). Viewing mesh models with associated data is an additional functionality included in CAD Assistant. Mesh can be read from files in PLY format.

Fast STL Viewer
Binary and ASCII STL files, 3D viewer models for Android. Show support for multiple files/models. Practical view modes: shaded, wire model, shaded + wire model, points. Front and back are highlighted with different colors highlighted. Fast loading of STL files/models. Support for large STL files/models (million triangles). Binary and ASCII STL files/model formats. Mains boundaries/edge detection. Separate (not connected) networks/parts detection. Selection function (hold a finger on a model to select it). To deselect a model, hold a finger on the background. Show bounding box information in the status per selection. Invert normal in a selected STL model. Delete a selected STL model from the scene. Open STL files directly from Gmail attachments, Google Drive, Dropbox, OneDrive via Fast STL Viewer. 3D printing with Treatstock option. The app's internal file manager tracks 10 recently opened files for easy access.

F3D
F3D is a fast and minimalist 3D viewer. It supports many file formats, from digital content to scientific datasets (including glTF, STL, STEP, PLY, OBJ, FBX, Alembic), can show animations and support thumbnails and many rendering and texturing options including real time physically based rendering and raytracing.
It is fully controllable from the command line and support configuration files. It can provide thumbnails, support interactive hotkeys, drag&drop and integration into file managers.
F3D also contains the libf3d, a simple library to render meshes, with C++ and Python Bindings, as well as experimental Java and Javascript bindings.

MeshLab
The open source system for processing and editing 3D triangular meshes. It provides a set of tools for editing, cleaning, healing, inspecting, rendering, texturing and converting meshes. It offers features for processing raw data produced by 3D digitization tools/devices and for preparing models for 3D printing. In this version we introduce support to several file formats (.gltf, .glb, .nxs, .nxz, .e57) and a brand new plugin for exact mesh booleans. The 3D data alignment phase (also known as registration) is a fundamental step in the pipeline for processing 3D scanned data. MeshLab provides a powerful tool for moving the different meshes into a common reference system, able to manage large set of range-maps. MeshLab implements a fine tuned ICP one-to-one alignment step, followed by a global bundle adjustment error-distribution step. The alignment can be performed on meshes and point clouds coming from several sources, including active (both short- and long-range) scanners.
