DESCRIPTION

glgrib is an application to display fields encoded in GRIB edition 2 using OpenGL.

Features : raster, contour, vector, colorbar, mapscale, coastlines, borders. Lat/lon, lambert, gaussian grid. GLFW backend for interactive display (glgrib-glfw), EGL backend (glgrib-egl) for batch processing without X11 display.

Tested on :

VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)

VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
