First one looks correct - I guess the problem lies in saving the blocks as polygons and then transforming those polygons. Any system is going to warp them, and it will look wrong. I'd save the blocks as just two endpoints through all the transformations, and add thickness later. Edit for new page, I'm talking about this:

It's not the sleepers that's the deformation, I know they'll always deform and it's not realistic, I'm talking about at the 45 degree angle the exposed end of the track is all squashed and short. Though that endpoint tracking + thickness idea is neat.

Though that endpoint tracking + thickness idea is neat. Translate the midpoint of the exposed end instead, and calculate the track positions off of that? Same basic idea as beta's recommendation for the sleepers. You only have two points that are free: the centers of the tracks at either end. Everything else should be calculated from those. What are you generating those curves from? EDIT: The variables I'd use are the center points of the track at either end and two vectors specifying incoming and outgoing directions, and then constrain the tracks to follow a circular arc.: 1. Calculate the radius and center of the circle from the two points and directions. 2. Add or subtract the separation of each line from the center arc. 3. Draw circle arcs of those radii with the same center and subtended angle as the center's arc. A straight track segment has an infinite radius, so you'll need to special case it. EDIT2: Like this.

Any system is going to warp them, and it will look wrong. I'd save the blocks as just two endpoints through all the transformations, and add thickness later. Yeah this was what I was getting at - treat the midline for each sleeper as between two points, one on each track line, and let the function move the points. You end up with a rotated line and you just need to align the sleeper with that. I guess the slight complication is that tight turns with short spacing will end up trying to cram several sleepers into the inside turn, and you might get overlaps. But yeah I wasn't sure if the whole thing was the output of a function, like... I guess I'm not very good at explaining this, but like the kind of things you can do with a graphic calculator. Drop in some equation and it traces out the shapes, y'know? If it's a more complex program where you can draw the sleepers separately then it could work out ^^^ That up there looks awesome though, and I love how the internet lets people do things like that to give examples. Hey here's some live animated code!

My 2D vector water test gone horribly wrong: A point is chosen as if something struck the water at a certain speed. The waves propagate, but feedback on themselves at greater and greater magnitudes.

I'm guessing it clears where you currently are not where you last were which means on the way down it leaves a trail.

I transformed the canvas I was drawing on to accommodate the scale/skew of the object I was drawing, and didn't reset that transform before clearing it for the next frame. (In addition, I failed to allow for my sprite's pivot point so it was drawn half a body height too far up)

 First time running the game with all the art setup for 1920x1080. It 'works' at least. But I still need to apply the scaling to all positional and more importantly sprite sizing code :P

I know it's probably shameful to post gifs that were taken from videos of my screen, but I'm lazy I guess and it's running on an iPad: I got the waves and propagation right, but when attempting to fill it instead of using lines, it looked really glitchy and found that I couldn't create concave fills, so I had to break it down into smaller convex polygons. Before using fills, it was best to see what it was doing using lines. As you can see, something was screwy. I've since fixed it for the most part.

Do you have timers on those missiles so they can finally blow themselves up if they don't hit anything? Because you probably should.

The 'wall' is a small representative section of a very big spaceship, made up of individual components with behaviours that affect the components around them. And yes, I added timers (and proximity detonation) and the missiles now work gloriously.

Man, that water thing has come a long way. I finally nailed it down and looks pretty good, and there's a ton of options you can play around with. However, I don't have a lightning bolt connector on my iPad 2, so I'll have to capture it with an HDMI connector or something. I'm in a video suite, so they'll figure it out.

One of the new features coming soon to VLC for WinRT is a new music player view. It looks pretty nice so far: The background is replaced with the artist image, and it stays there throughout the UI. Only it does not go away if you switch to a video...  I love the idea of Frank Black just staring at me when watching old Lowtax videos.  .

Remember that if you render it with back culling on and indices in clockwise order then it will go bad. Also, am I seeing Z-buffer issues? Edit: This is OpenGL, right?

It is OpenGL, though I should've explained that I got it fixed. It was actually a two part problem, the first being that I mixed up the normal and texture coordinate indices, and the second was that I was loading the texture upside down, so the texture coordinates were sampling from an alpha section. I was just outputting the texture RGBA directly, so that's why it has all those weird gaps. It's a little hard to make sense of it as an image so I made a gif of it:  It looks like this with lighting now:
