Tessallate to get triangles strips

Hi All,

I'll try to be as specific as possible. If I'm not clear, please let me know.

I'm using version 8.0 of the SDK.


I'm parsing a JT file using the jtkTraverser class and a callback.

In that callback, as shown in the traverse sample, in case I find a jtkPart, I aim to tesselate this jtkPart into jtkTristrip a stated page 173 of the functional_description.pdf.


The problem is that he part returns 0 when I call numTessParams on the jtkPart.


I tried creating my own polygonset after calling getInternal and getinternals on the shapes of the part to pass it to JtkEntityFactory::createTriStripSet but the model contains part set that are edges (2 vertices) and not triangles.


What would be the good method to tessellate a jtkpart to triangle strips when numTessParams returns 0 ?


I can give details if I'm not clear enough.


Thank you for your help, guys.

Answering my own question here.
Problem solved taking a direct way: cast jtkPart depending on type, a simple switch and it works.


What is JT?

JT is the World’s Most Widely Used 3D File Format for PLM

JT is the common language of PLM and is the world’s most widely used 3D format. JT is the first ISO International Standard ( IS 14306-1) for 3D visualization and collaboration. Compact and accurate, JT is used throughout the product development lifecycle in all major industries to communicate the critical design information typically locked up inside a CAD file.

Siemens PLM Software customers rely on JT to be the most robust 3D visualization format available.
