BUGLE-EPS(7) Bugle user manual BUGLE-EPS(7)NAMEbugle-eps - captures vector graphics representatios of scenes
SYNOPSIS
filterset eps
{
filename "screenshot.eps"
key_eps "key"
title "My screenshot"
bsp "no"
buffer "10000000"
}
DESCRIPTION
This screenshot is similar to bugle-screenshot(7), but instead of a
raster image, it produces a vector graphic suitable for printing. This
is achieved through gl2ps[1], which is incorporated into bugle. The
supported formats are Postscript, Encapsulated Postscript (EPS),
Portable Document Format (PDF) and Scalable Vector Graphic SVG).
The capturing process utilises the OpenGL feedback buffer (see
glFeedbackBuffer(3)), which creates some inherent limitations. No
per-fragment effects (such as texturing or bitmap rendering) are
captured, not will vertex programs work correctly. Essentially, the
colour of each vertex must be either directly specified or determined
by the OpenGL lighting model.
OPTIONS
filename
The file to which the screenshot will be written. The extension is
used to determine the file format. Valid extensions are .ps, .eps,
.pdf and .svg.
key_eps
The key-press which triggers the snapshot.
title
The title that is embedded in Postscript and EPS files.
bsp
If this boolean is enabled, the depth sorting is done with a BSP
tree to give accurate results. This may be necessary to get correct
results in scenes with complex occlusion, but it is much slower.
buffer
The number of entries to allocate for the feedback buffer. If this
is too low, the feedback buffer will overflow and the screenshot
will fail. The default should be enough for most simple scenes, but
for highly complex scenes it may be necessary to create a larger
buffer.
