What is a WRL File?

Wed Jan 15, 2020

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.

The Main Benefits and Disadvantages of Voxel Modeling

Wed Dec 18, 2019

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.”

The Main Benefits and Disadvantages of Point-Cloud Modeling

Tue Dec 17, 2019

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.

The Main Benefits and Disadvantages of Polygonal Modeling

Tue Dec 17, 2019

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).

The Main Benefits and Disadvantages of BRep Modeling

Fri Dec 6, 2019

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.

CGM Core Modeler Enhances Feature Recognition

Tue Dec 6, 2016

The 2017 1.1 release of Spatial’s CGM™ Core Modeler improves the robustness of its feature recognition capabilities by extending the range of recognizable structures. Feature recognition rapidly identifies manufacturable structures in a model (such as holes, pads, logos, etc.), enabling users to group and perform subsequent operations on these constructs. This capability enables improvements to many workflows, such as reducing complexity for downstream simulation and analysis.

Geometry for Bevel Cuts using Water Jet & Laser Cutters

Wed Mar 16, 2016

As water jet and laser cutters become more sophisticated, the geometries that they are able to cut are also increasing in complexity.

Healing Gaps in CGM

Fri May 15, 2015

As we live in a less than perfect world, 3D CAD models are far from perfect. Particularly, models often times contain gaps, which can be found between adjacent vertices, edges, and faces.

Application Driven Documentation

Fri Nov 16, 2012

In this post I’m going to talk about how we use C3D Toolkit to generate 'live' sample code snippets for our CGM documentation.

How to Train Eight People Without a Trainer

Tue Apr 17, 2012

John's recent post on documentation and behavior driven development reminded me of an interesting experience I had last fall in developing training documentation.  Our annual 3D Insiders' Summit (early bird registration is now open, by the way. We hope to see you there!) always gives the sales team a rare opportunity to come together from around the world in one geographic location with a large chunk of the development team.  We decided to take the time to have some introductory CGM training for the TAMs (Technical Account Managers), and through the process of elimination, I somehow landed the task of organizing it.
