Abstract
Meeting the demands of the current tera-scale visualization
community requires the use of large- and small-scale tiled displays. The
Lawrence Livermore National Laboratory (LLNL) efforts in this area have
led to the creation of one of the largest interactive tiled displays
built to date, and a number of new efforts for “personal”
tiled displays. Visualization hardware and software now being built will
display up to 15 times the number of pixels in a typical desktop
display. We outline the system implemented at LLNL for the creation and
support of large, tiled, multi-pipe graphics displays. The system builds
on a simple, portable, parallel API for tiling OpenGL commands in
parallel to multiple contexts on a set of X servers. This API has
allowed us to retrofit existing visualization and analysis codes to
support these displays with very little effort. While this work
represents a first step toward the ultimate goal of scalable
visualization in individual office spaces, the result has been the
creation of useful new visualization workspaces and tools for our users
