jpeg2qtvr

Fri, 17 Nov 2006 09:42:03 +0000

A tool for assembling six JPEG cube faces into a QTVR file. This is currently a single perl script with no external dependencies, it should run on any platform.

Usage: jpeg2qtvr [options] --prefix=PREFIX > OUTPUT

eg. use --prefix=foo_ if the front, right, back, left, up and down JPEG tiles
are named foo_0.jpg, foo_1.jpg, foo_2.jpg, foo_3.jpg, foo_4.jpg and foo_5.jpg

Options

 --date date in seconds since January 1st 1970, defaults to current time
 --name title of the panorama
 --width preferred window width, defaults to 1024
 --height preferred window height, defaults to 768
 --outfile name for output mov file, otherwise result goes to STDOUT
 --pan initial pan (yaw), defaults to 0.0 degrees
 --tilt initial tilt (pitch), defaults to 0.0 degrees
 --fov initial vertical angle of view, defaults to 60 degrees
 --min-fov minimum vertical angle of view, defaults to 10 degrees
 --max-fov maximum vertical angle of view, defaults to 120 degrees
 --preview prefix for preview track JPEG tiles

It is approximately feature-comparable with freepv, the free QTVR viewer. Advanced features such as sub-tiling and header compression may be added later (but may not).

Enblend Mask

Tue, 17 Oct 2006 22:03:01 +0000

This is a page explaining a couple of experimental scripts developed for working with enblend masks.

The first script is a simple wrapper, it behaves exactly the same as enblend except that it allows the use of external mask files rather than just internal alpha channel masks. Use of these mask files is automatic, for example: if myfile.tif is an image to be blended, the script looks for myfile_mask.tif and applies this as the mask before blending.

Police launch biggest operation to tackle drunken thugs

… Officers holidays and shifts have been re-rostered for the entire competition with particular emphasis placed on England match days — The first of which kicks off tomorrow.

Stained glass window at Shirley House

Here is a problem, the tonal range of this stained glass window in Shirley House is too wide to photograph, here is a bracketed series of pictures of the window:

Fisheye to Stereographic

Sun, 02 Apr 2006 11:43:33 +0000

Fisheye images are a way of representing a photograph with an angle of view greater than 180°. Stereographic is a conformal cartographic representation that has similar properties but with less dramatic distortion: http://en.wikipedia.org/wiki/Stereographic_projection

This experimental tool (requires the Imager and Parse::RecDescent perl modules) converts from fisheye format to stereographic:

The following pair of images show a partial 288° fisheye view created in hugin and then converted to stereographic.
