How to convert JT (Jupiter Tessellation) to OpenGL C Code (.cpp)?


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.

     

JT

"JT" is the predominant and lightweight 3D visualization file format for PLM. 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. JT data can be very lightweight, holding little more than facet data or it can be richer and hold associations to the original CAD information, assemblies, product structure, geometry, attributes, meta data and PMI. It supports multiple tessellations and level-of-detail generation.

Okino was one of the very first members of the Siemens 'JT Open' initiative and hence we provide excellent support for the import and export of JT files. We do not use reverse engineered toolkits but rather the officially licensed runtime systems from Siemens Corp.

     

OpenGL C Code

OpenGL is a cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.

Okino's OpenGL export converter writes out the scene database as a C code program in the Open GL scene description language. The resulting program can then be compiled and used to draw the 3D database directly using OpenGL. The database is output as a series of polygons with vertex positions, normals, colors and texture coordinates. In addition, the surface definitions (materials) associated with each polygon is used to set up the OpenGL shading parameters. Please note that each object is output as a separate C code function in the resulting file.
