How to convert SketchUp (.skp,.skb) 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.

     

SketchUp

SketchUp is a popular 3D design product originally developed by @Last Software and now owned by Trimble, Inc. It uses the .skp and .skb file extensions.

Okino recognized the growing popularity of SketchUp (well before it was purchased by Google and then Trimble) and as such we worked directly with the original SketchUp developer to create the first set of independent, professional and fully compliant SketchUp 3D converters outside of the SketchUp program itself.

     

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.
