There were
some other client specific projects:
Client: SGI India Bangalore, India
April - Aug, 2006
The project was for one of the SGI's customers in
India. SGI's customer wanted to
interactively visualize their
large Aircraft model data on SGI's multiprocessor-multipipe visualization
system Onyx4. The aim of the project was to demonstrate that SGI's hardware can
perform up to customer's expectation and can fulfill their requirements.
Tasks and Responsibilities:
·
Developed application to interactively visualize
customer's large Aircraft data managing multipipe processors, multiple graphics
pipes and SGI's Scalable Graphics Capture (SGC) cards available on the system.

Client:
A software product company in CAD/CAM/CAE Area Bangalore, India
July 2006 - Present
The Aim of the project is to find the replacement of
Cosmo3D/OpenGL Optimizer API and move away to some other SceneGraph based API
depending upon client's requirements.
Tasks and Responsibilities:
·
Investigating about available SceneGraph APIs like OpenSG,
OpenSceneGraph, nvSG etc and determining their pros & cons based on feature
set needed by the client.
