Perspective projection

I've always been interested in Computer Graphics. This area of computer science unites most of the things I´m interested in. From pure maths to algorithm analysis, and software engineering, if you want to be a good graphics programmer, you need to master of this fields of knowledge.

The purpose of this post is to provide a set of interesting links about perspective projection. This concept is absolutely essential to understand modern graphics, especially 3D game graphics. Thanks to APIs like OpenGl or DirectX, you don´t have to program your own projection, but you need to understand what is going on under the hood to be able to make the most out of it.

• Siggraph Perspective Viewing Projection. This is a rather mathematical explanation, but is there any other way.
• Client Management Systems, computer graphics introduction. No maths at all, so this is a good starting point.

The Corrib river, Galway

The Corrib river crosses Galway. Actually Galway is the last place the river passes before reaching the ocean. This afternoon I gave a walk and took some pictures of the river. I hope you enjoy them as much as I enjoyed the walk:



Then I continued walking and after approximately 30 minutes I arrived to the docks. This area of the city, as it´s name indicates, is where the ships "park". There are lots of warehouses, and industrial stuff scattered across the area. Among all this things I found this structure, that seems to be part of a crane:



Lovely afternoon indeed.

Cheers!

Streets of Galway 08, Results

Probably this post should be called "Streets of Galway 08, my results", because is only to inform about me, jeje.

Well, my most optimistic forecast was to run the 8K in 34 minutes, and honestly this wouldn't have been a bad time, but that Saturday 9th of August I was in a good mood so I decided to push a little bit harder and finally my time was 32 min 50 seconds. My position was 170 out of almost 2000 participants.

The race was wonderful the atmosphere thrilling and on top of that a didn't suffer at all during the race. This tells me, of course, that I could have done a better time. My best Irish race so far, but many more are yet to come.

Streets of Galway 08

Next Saturday 8th August take place the major running event in Galway city, the Streets of Galway. This race is organized every year by the Galway City Harriers, and sponsored by Future Financial Services.

It´s is a 8K long race. My last 8K race was in Maree, and there I did a 4:20 per K average. Last Monday I did an 8K test at almost race pace, and it took me 34:27, which means that I can improve my result in Maree.

The anecdote of this race is that I was absolutely convinced that the race would take place the 1st of August. With this in my mind last week I planned a really soft training, and on Friday I called the organization because I hadn´t received the race pack (chip and t-shirt), only to discover that the race wasn´t that Saturday, but saturday week.

I hope this event doesn´t affect my performance, I´ll inform you soon.

Bye!!!
