Geometry Systems Inc.
GSI Studio: for entertainment and
engineering applications involving model viewing,
model orientation, mesh alignment and merge, mesh healing,
mesh sculpting, curve network creation, NURBS surfacing, restructured
mesh/grid generation, 3D paint, and texture mapping.
GSI Mesh Studio: for 3D polygon mesh applications
covering scanner control, mesh alignment and merge, mesh healing,
and mesh sculpting.
GSI Crystal Studio - for laser sub-surface
engraving applications. It handles both 3D and 2D
images to create precisely positioned point cloud ready for
laser engraving machines.
GSI Crystal Plus Studio - in addition to
the functions of GSI Crystal Studio, it provide the functions
like mesh align and merge to create 360 degree point cloud
instead of just the frontal view.
GSI Viewer Studio: for general 3D model
viewing and display.
GSI Orchestra SDK - in addition to the end-user
products, GSI also offers a development platform for customers
and partners to develop their own application specific tools
and solutions quickly and economically.
A typical workflow form mesh to NURBS surface is shown below:
The original model is:
Step 1: Scan a model into computer
Step 2: Align the scanned meshes
Step 3: Merge the aligned meshes
Step 4: Fix hole and smooth mesh
Step 5: Create curve network
Step 6: Create grid/restructure mesh with LOD management
Step 7: Create NURBS surface with boundary continuity management
Step 8: Output NURBS patches, curves, restructured mesh, grid,
texture map, etc
*We want to express our thanks to Michael Garland
for Mixkit, Mensi for their SDK, Minolta for their DSK, Cyberware
for the sample echo file IO, Imagemagic, OpenNURBS from Rhin,
and qhull code. Our align and merge software is based on the Scanalyze
system developed at Stanford University for the Digital Michelangelo
Project and we like to thank Stanford University for their great
