Pushing Pixels

About a year ago I wrote about the Photosynth technology from Microsoft that creates 3D spaces from collections of photographs. At the time it only worked with a few sample data sets created by Microsoft, but there was a very nice demo to download and it was a pretty exciting piece of tech. Just a few days ago Microsoft released a full version that allows you to create your own “photosynths” by uploading collections of photos.

I just had to have a go. The image above shows a screen-grab of the Photosynth viewer with some data that I took.

Read on for more on the new release, how I got on with it, videos and links to the 3D scenes that I created.

Setting off, 5pm Friday

In this second article on my recent 3 Peaks challenge I describe the hikes themselves and the transits between the mountains. See Part One for a description of the challenge, and Part Three for preparation, training, kit and tactics.

My personal times were:

So as you can see I did succeed and completed it - I got to the top of Snowdon in a shade over 23 hours. I was a little disappointed not to get down again within 24 hours, but as you will discover when you read the account of each mountain, I just count myself lucky to have even finished at all, irrespective of times.

On the weekend of June 20th I took part in the national Three Peaks Challenge to try and climb the three highest peaks in the UK mainland within 24 hours. Starting off at Ben Nevis (1344m) in Scotland, I also climbed Scafell Pike (978m) in the Lake District, and ended up at Mount Snowdon (1085m) in Wales. In all there was about 25 miles of walking, hundreds of miles driving, and not too much sleep. I was part of the Long Eaton Round Table team of 20 walkers attempting the challenge, all to raise money for various charities including Multiple Sclerosis research. I’ve written here the story of the team’s efforts. But this post, however, is intended to be a more personal account of the challenge itself, the training and the preparation that went in to it.  Along the way I’ll mention a bit about taking photos on the way. Hopefully it will provide an interesting and useful resource for others who are doing the challenge too.

This is the first of three articles on the challenge, describing what it is and how we went about it. Part Two will go into the experience itself, and the final part will explore training, kit, and preparation.

Something that caught by eye on the Digital Urban blog was a reference to a fantastic little website applet that shows Flickr slideshows with a difference. Called Flickrvision, it shows a near-realtime view of images being uploaded to the Flickr online album website, overlaid on a map of the world. You can overlay the pictures either on a normal 2D Googlemap or, as the screenshot here shows, onto a 3D view of the Earth which spins around to help position the images.

Flickrvision in 3D mode

You can go straight to the 3D version by clicking this link. There’s no need to install anything - just click & go. To switch to the Googlemap version, just press the “Classic View” button that appears on the screen. It is a great page to just leave open on your desktop, especially if like me you have a two screen set-up.

A game you could play would be to upload photos to Flickr and watch to see if they appear on the globe. Have your favourite screen grabber tool at the ready…

A quick follow up on the post a couple of months ago about my quest to find a simple way of embedding Google Maps in Wordpress blogs. Just to recap, the main issue I had was finding a way of embedding custom maps.

While I still have yet to find a solution to self-hosted Wordpress blogs like this one, there is a good solution for anyone who has a blog hosted at Wordpress.com. For those of you that don’t know, this is a site that looks after thousands of Wordpress blogs for free. They run their own specific version of Wordpress - you can’t get at the PHP code or install your own plugins. But it’s a great way to host sites at little or no cost. I run a couple of community sites hosted there, both for the Round Table organisation - see Long Eaton Round Table and also the Area 14 sites.

That version of Wordpress provides a tag - “googlemap” - that can take any Google Map reference including custom maps and embed them in the page properly. It works really well - for an example, see the About page on my Area 14 site. Instructions for using the tags can be found here.

Now all we need is the same thing on the regular version of Wordpress, and I’ll be a happy bloke.

Just a quick note to describe some recent changes to this site.

I’ve changed the template from the attractive but not easily configurable “Feather” theme to Chris Pearson’s “Cutline 3 column” one. The initial advantage of this was it was easy to set up my own header images to be my own photos rather than someone else’s. All the headers are my own.

While it was nice to have each individual page type (posts, archives, pages, about etc) have their own header image, Chris posted a simple mod to the header PHP file that randomly selects an image from a set. Every time you visit the site or refresh a page you’ll get a different header. I intend updating the image set as often as I can. If you read further down this post I have described the header images currently in use.

But there have been more changes than this.

I have been creating my own Google maps a lot recently, largely in support of an upcoming attempt at the 3 Peaks 24 hour challenge - hiking up the three highest mountains in the UK all in 24 hours. I’ve got various maps for the three hiking trails, plus a few put together to help plan training walks.

I’ve been scratching around for a while experimenting with various ways of sharing these maps, and embedding within a Wordpress blog seems a good thing to do.

While out walking one chilly morning in Attenborough nature reserve I spotted this Robin. Luckily for me he was in posing mood and I managed to get pretty close with my 200mm lens. The image is uncropped - I got within just a few feet of him.

I got some nice comments on the image from the people over at Flickr.com, and thought it worthwhile to post here too (see the links panel for more of my pictures on Flickr). I’ve also recently been getting into Flickr a lot, and this was an opportunity to link my gallery straight to this blog for a bit of a test. Regular readers will have noticed that at long last I have chosen a different theme - the header images are all mine, although I plan on randomising the set to add a bit of variety.

Hopefully this hooking together of online galleries and Wordpress means I can keep my earlier promise of updating this site more frequently.

The sign of a bad blog is that it hardly ever gets updates. In other words, this one!

It’s hard to believe that six months have gone by without a single new posting, which is rather poor of me. My only excuse is that I have a life, and finding time to write some coherent thoughts on things, at the expense of other activities, is often too hard to justify.

And yet there is lots I would like to chuck out there, and lots of things I have been experimenting with or starting to use. For example Fogbugz (a software management tool), how do you choose an online gallery, and DIY desktop mixed reality. So here’s hoping I get the chance.

The picture introducing this post is a Long Tailed Tit I spotted while walking in Attenborough nature reserve, using my new Canon 80-300mm IS (Image Stabilised) lens. It was pretty much a reaction shot - the bird did not sit still for more than a few seconds, and I have several pictures showing empty twigs with just the blur of a tail feather exiting the frame. Click on the image to see a bigger version via Flickr (since this was originally written I’ve been getting to grips with this online gallery).

I’m pretty impressed with the lens so far, even after just a single brief outing. I got it for wildlife and sports/action photography. I still need to experiment with the image stabilisation feature to get the best out of it.

A few weeks ago I wrote about using Panoramio to publish and view images from around the world in Google Earth and Google Maps. At the time I posted just a single beach scene from Hamilton Island in Australia as a test image and noted that it takes a while for these images to appear to any user of Google Earth. At long last these have now appeared!

After I wrote the article I added a few more images I had lying around. After a few weeks, they started being flagged by the Panoramio reviewers as having been accepted by Google Earth.
