How to convert STL (StereoLithography) to Houdini?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

STL

STL (StereoLithography) is one of the industry's oldest (and simplest) 3D file formats created back in 1987 for 3D Systems' first commercial 3D printer. It is widely used for rapid prototyping, 3D printing and CAM. Okino has provided one of the very first and still primary STL export conversion systems for close to 3 decades.

Please take note that there is no 3D file format which is much simpler than STL. It is not a high-end, high fidelity 3D conversion file format as many people have come to wrongly believe. Rather, STL defines just a raw triangulated polygon mesh with no smoothing information (vertex normals), no uv texture coordinates, no assembly hierarchy part naming or any material assignments. 3MF and VRML2 are often much better file formats for moving 3D datasets into downstream programs and/or 3D printers.

The Okino STL exporter WEB page provides good graphical tutorial about how to convert CAD file data into STL and also how to clean a 3D model which is 'almost water tight'.

Houdini

Houdini is a 3D animation software application developed by Toronto-based SideFX, who adapted it from the PRISMS software tools. Houdini is most commonly used for the creation of visual effects in film and television.

Being both from Toronto, Okino has known the original 3 developers of the PRISMS/Houdini software since 1991 and have kept a close relationship with some of them. Given the very niche markets into which Houdini has been sold since the mid 1990s, we do not get many requests for the conversion of data in or out of Houdini compared to our primary 3dsMax/Maya/Cinema-4D daily requests. Nevertheless, we developed our FBX and COLLADA converter modules to be compliant with the Houdini software.
