It sounds like you're asking for a guide or technical paper on converting VVD (likely a proprietary or less common format, possibly from medical imaging, simulation, or 3D scanning) to OBJ (a standard 3D model format), with emphasis on topology (maybe “top” refers to topology optimization or preserving top-level structure).
However, “VVD” is ambiguous. In 3D graphics contexts, VVD could refer to:
Below I’ve written a useful, practical mini-paper focused on the most common scenario: Valve VVD (vertex data) + VTA (vertex animation) + VTF (textures) to OBJ, preserving topology.
The VVD header begins with a magic number identifying the file type, followed by version numbers and a checksum (CRC). Crucially, the header defines the numLODs (number of Levels of Detail) and the numVertices. It also contains offsets that point to where the vertex data actually begins within the binary file.

The fundamental difference between VVD and OBJ lies in data organization. OBJ utilizes an "Array of Structures" approach:
This separation allows for memory optimization in file size but requires a mapping step during conversion. An OBJ face definition references the indices of the previously declared vertices, UVs, and normals.
To understand the conversion, one must first understand the source material. The .vvd file format is proprietary to Valve’s Source Engine. It is part of a triad of files that define a 3D model:
The VVD is essentially the "flesh" of the model, storing the shape of the object. Unlike a standard OBJ file, which is human-readable text (in its basic form), a VVD file is binary and tightly packed for efficient memory streaming by the Source Engine. Top Tools for Converting VVD to OBJ Here

OBJ files are often accompanied by MTL (Material Template Library) files. However, VVD files do not store textures; they only store UV mapping coordinates. The converter can generate an MTL file, but it cannot extract the textures themselves (which are in VTF format). The user must manually assign textures or convert VTF files to TGA/PNG separately.
