VRML in Manufacturing

[talhah]

Hi,
I hope to guide me for any website or free papers about VRML used in simulation in manufacturing engineering

VRML is an approximate representation of 3D geometry using tesselated surfaces i.e. flat triangular mesh fitted to the surface. You can control the accuracy & reduce the error to the true surface by increasing the # of triangles. Most CAD & CAE software can easily create VRML output as .wrl files.

VRML is popular because it is a very light (small file size) & simple (points & lines) representation of complex 3D geometry & is often used for visualization (on the web & in s/w) & in process simulations where approximate geometry is sufficient. It is not used in product simulations such as FEA where the true 3D geometry is used to generate the mesh needed for the simulation but the FEA mesh can be exported as VRML files also.

Here is a link to the W3C site that defines the VRML standard

Hi Deb,
Yes, I mean VRML in Process Simulation in manufacturing

This seems a good paper. Also check out the References at the end of the paper.

Dear Deb,
Thanks for your efforts.
With my regards.
