Description

Watch the GTC session about the technology behind this imaging at http://nvda.ly/NgAUY. Immersive Design Studios bridges the transition from FPGA to GPU-based image processing with our proprietary software - CANVAS: a GPU image-processing platform designed for various AV applications including multi-screen warping, blending, pixel- mapping and color matching. We will present a case-study based on a project at Montreal's Bell Centre hockey arena, featuring projections on ice during the 2013 NHL playoffs. The installation required image warping and blending with 12 overlapping projectors -each set of 6 projectors mapping in 6K onto the arena ice. The use of CANVAS allowed for pixel by pixel resolution, easy warping and blending, as well as cutting the projector calibration time from 8-12 hrs down to just 15 min.
