What NEXUS Model Converter is
NEXUS Model Converter is a free toolset for creating and viewing batched multiresolution 3D models. Nxsbuild converts .ply or .obj files into multiresolution .nxs models and can combine multiple pieces into one file. The format supports point clouds and meshes with per-vertex normals, colors, and texture coordinates, while textures are stored internally. Its view-dependent structure allows different resolution levels during viewing. Nxsedit can compress models, prune lower hierarchy levels, export to .ply, and report model information; the project states compression can reduce model size to 10–20%. Out-of-core tools process large models and textures with limited resources. Nexus also supports network streaming and compression for streaming applications. Web projects can use its WebGL library, Three.js loader, or 3DHOP rendering engine. C++ software is GPL, JavaScript software is MIT, and Windows executables and source code are available from GitHub releases.
Good
- Free C++ and JavaScript software
- Converts .ply and .obj inputs
- Supports point clouds and textured meshes
- Includes WebGL, Three.js, and 3DHOP integrations
- Out-of-core tools handle large models
Watch out
- Nxsbuild's 2000 MB RAM default is not a hard limit
- Windows executables are provided, but other desktop binaries are unspecified
- C++ software depends on Qt and VCG lib
- No free trial is offered
Who it suits
It suits developers adding multiresolution 3D visualization to C++ or JavaScript applications. It also helps users preparing large models for web viewing or streaming.
Verdict
NEXUS Model Converter provides conversion, editing, streaming, and web-rendering components without a listed price. Its multiresolution workflow and integrations are useful for developers, while resource handling and licensing dependencies deserve attention during setup.
