I created a page for xscreensaver hacks http://www.jumpstation.co.uk/xscreensaver/ especially http://www.jumpstation.co.uk/xscreensaver/topblock/

topBlock release version 1.0 is now ready.



I will be working on a page to celebrate its birth into the world soon ...

This line notes almost being crushed by a slam man full of sand !

I had a small emergency when all my openGL stopped working system wide, after a lot of playing about and at one point losing Xorg I found that I had a new kernel built that I had never rebooted into, after rebooting into the 2 month old kernel and a bit more mucking about everything is good again.

I have finished reading the "call of cthulhu and other weird stories" another collection of HP Lovecraft's tales. This one was much more accessible then the "Dreams in the witches house" but ultimately less interesting. I was particularly  let down by the infamous "Call of Cthulhu" which goes no where.

After that I bought RG Veda a clamp English manga, which in true Japanese style is read right to left, loads of fun but did not fill in the blanks from the video :(

Its still not quite ready but I added wire frame mode (left) and then quickly fixed the colors (right) plus loads of other modifications including the long awaited recycling of used blocks.

In hours of posting the geourl I got an email from the http://www.bagofspoons.net site owner who is involved with the semi local Lug http://www.herts.lug.org.uk/

The Java rotation code converted to C very easily and I now have the full X,Y,Z rotational tracking in the topblock code.

But there is an awful lot of tidying up before it is finished, stay tuned.

I have created a page http://www.jumpstation.co.uk/rotation/ that contains the Java applets I created to get my Maths right plus some information on how its all pulled together.

Unfortunately this means I have not actually had any time to work on the screen saver that is to receive the code.

I am still have problems with rotations in 2d space, so much in fact that I think I will write up all the Java applets I am writing to test theories and offer some one else a chance. 

Of course if I had only paid more attention in Maths class ... (blame the teachers)

I have had enough spam for a while, so I have gone back and updated ALL the pages on this site to use my javascript write email address function, I can not filter 90% of my spam away !

I finally got around to watching the 2010 DVD I bought in Ireland and was disappointed to find I had seen it before, but it is good, I might even buy 2020 (book) to find out what happened next.



This line marks the passing of fluffy ... all the best

Although not implemented I have (I think) worked out how you can track a object rotated about a distant axis.

Imagine a chess board with a pin in the center, in the bottom left hand corner square is a prawn (slightly frozen).

You are a fixed camera looking at the board as a human sitting at a table with the board in front of them might.

Directly in front of you is the center of the board, to your left and low in your view is the prawn.

You rotate and tilt your head/camera to view the prawn, the board turns slowly, the prawn moves (as the board rotates) up and right eventually leaving your field of view.

Thats the problem I want the camera to track the moving prawn, turns out I can get the distance to the prawn from the center using Pythagoras then I can use trig to get the angle, and on the rotation to get the new angle and the use Pythagoras again to work out the Adj and Opp sides which are the offsets to move the camera in 2d space, phew.

Now to implement it ....
