I swear the web hates things being centered! 5 months ago I updated the splash page of my personal website: https://roy-t.nl.

I am certain that at that time the div marked red in the image was centered. But today I noticed that its now aligned to the right.

No clue how to get it centered again :/

My tiled terrain in all its glory. Rendering, picking, modifications and updates in a background thread. Lots of work to replicate something as seemingly simple from games from 25 years ago.

In my tile based terrain I first naively drew each tile as two triangles and each tile border as a line segment. A 128x128 terrain was rendered using 32768 triangles and 33282 line segments!

To optimize this I wrote a O(n) algorithm to assign tiles into rectangular zones. Each zone can be drawn using just 2 triangles. For this, relatively flat, terrain this means I only need 5974 triangles. Only 18% of the original. As you can see I even merge angled tiles into zones.

Generation of large tile/grid based landscape is coming together nicely. #gamedev #gamedevelopment.

Its still relatively slow. I can optimize the number of triangles being drawn a lot by merging tiles. But I'm not sure how to optimize the grid rendering.

Wonder if I can do that completely on the GPU, without drawing any primitives, if I do something smart in the pixel shader. Like a distance field based on world coordinates?

Random doodle, while trying to figure out a problem I was having with normal computation. Not particularly helpful for anyone but me. But it made me wonder, what do you do when you are trying to solve a problem?

This was done in http://getpaint.net, but I also make heavy use of the graphical calculator at http://desmos.com/calculator
