WRL files are an extension of the Virtual Reality Modeling Language (VRML) format . VRML file types enable browser plugins to display virtual reality environments. The term VRML is often referred to as “worlds” or vrml world file - which is also what WRL actually stands for.
Voxels are to 3D what pixels are to 2D.
Firstly -- let’s examine what pixels actually are. Everything you see on your computer screen is made up of very small squares called “pixels.”
Point-cloud modeling is typically used in the process of 3D scanning objects.
Rather than defining surfaces through mathematical formulas, or building them out of rudimentary shapes like triangles -- point cloud modeling creates a representation of a 3D object with densely placed vertices -- or “points” -- along its surface.
Polygonal (or polyhedral) modeling is the most common type of modeling for video games and animation studios.
This type of modeling builds 3D objects out of smaller components called “tris” (triangles) or “polys” (polygons).
BRep modeling, or Boundary Representation modeling, is, in CAD applications, the most common type of modeling. BRep is a mathematically precise representation of a 3D object. This representation defines the geometric boundaries between solid and non-solid geometries.
In a recent blog post (Healing and Preserving 3D Model Intent) and eBook (Healing as an Essential Function), we wrote about the healing process within the 3D ACIS Modeler and 3D InterOp on precise (B-rep) models. To recap, healing is the process of modifying model data so that it conforms to the rules of the target system, while adhering to the intent of the source.
