X3D is ISO standard XML-based file format for representing 3D computer graphics. X3D features extensions to VRML (e.g. CAD, geospatial, humanoid animation, NURBS etc.), the ability to encode the scene using an XML syntax as well as the Open Inventor-like syntax of VRML97, or binary formatting, and enhanced application programming interfaces (APIs). The X3D extension supports multi-stage and multi-texture rendering; it also supports shading with lightmap and normalmap. Starting in 2010, X3D has supported deferred rendering architecture. Now X3D can import SSAO, CSM and Realtime Environment Reflection/Lighting. The user can also use optimizations including BSP/QuadTree/OctTree or culling in the X3D scene.
Parasolid file format is native for Parasolid geometrical kernel. Today it is widely used in a range of applications, including SolidWorks, SolidEdge, NX, Microstation, Ansys, Abaqus and others. Parasolid has two primary file extensions: .x_t, which is text based, and .x_b – binary-based format. Parasolid is also used to provide precise geometrical definitions of parts in JT files (as XT B-Rep data segments). CAD Exchanger can read files compliant with the entire range of Parasolid file format (schema) starting from v0.15 and up to version 32 (as of time of writing this page). Likewise, CAD Exchanger writes file compliant with all Parasolid schemas.
