Particle Physics using a Coupled Map Lattice

cml0

Hey! Been a looong time since I posted anything here. I just wanted to share what I’ve been working on the past few days as I thought I could get some cool gifs out of it.

This here is the beginning of an experiment to simulate some kind of particle motion in realtime. If I just figure out how to do this properly I can eventually use it for e.g. smoke, fire, cloud formations, water or cool displacement effects in my future applications. But it’s really haardd x) Fluid dynamics is one of my goals, I’ve been reading up on it, but as it’s based on complex physics equations, a lot of it is still incomprehensible to me. And my programming environment is lacking many features.

Anyway, this is what I’ve got so far. It’s done on my pc’s gpu in a glsl es shader so I’m constrained to parallell programming. But that’s a good thing; it allows me to render and update more than a million particles 60 times a second. A texel works like a particle storing information in its rgba channels. I store the visibility of the fluid in the red channel, and the velocity (vx,vy) in the green and blue channels. (Not using the alpha channel atm.) I draw the texture onto itself to update the particles. Since it’s parallell programming, I can’t actually move the particles. Instead I’m using what’s known as reverse advection to take the information from another texel by using the current texel’s velocity and “look back in time” advecting the visibility and the velocity itself. There are some really ugly artifacts in the gif though. I’m far from done if I want something near real fluid dynamics. Maybe I can use a blur shader to spread the velocities thereby removing the border artifacts, or just some kind of interpolation, or try to understand how others did it with the very limited number of resources I’ve found on the inernet x)

I’m not surprised at the amount of effort going into a 3D model game designed to look exactly like a 2D…  well… animated film… But I still can’t believe it. The game’s certainly capable of letting the environmental lighting take over in certain situations and scenes, but most of the time it uses hand drawn shadows and textures to present things as awesomely as possible.

There’s also little to no ragdoll or automatic physics. Just like a sprite based game, every single frame of every movement is modeled individually. Which is like saying “Hey you know how it’s easier to just have the physics automatic? Let’s NOT do that. Let’s make this look awesome. It’ll take forever and it’s just a for a split second movement, but it’ll be awesome.”

ArcSys how you manage to make a game as amazing looking as the FIRST GG was in its own time but in 2014? It’s 2014 we’re supposed to have seen everything.

Reversic Acid
Reversic acid is a rare fluid that can reverse the angle of light traveling through it. Science remains unable to completely explain the phenomenon, though it was known to Ancient Egyptians who believed it to be the work of Set.
When light travels through a normal liquid like water, the light simply travels through unaffected. But when light travels through Reversic acid, it gets confused and the photons forget which way to go, an interruption in what scientists call “Quantum Memory”. Magnifying glasses are assumed to work on a similar principle, in which the photons forget what size they are and grow larger.
Though practical applications are scarce, experiments have taken place to exchange the vitreous humor (The water inside your eyeballs) with Reversic Acid. The results as reported by the first test subject stated that he could not only see backwards, but backwards in time, thus witnessing his own birth.

So… can I drink it?

Reversic acid only has a Ph of 75 so it’s perfectly drinkable, but consider the effects if you did: First, your intestines would twist around to flow in the opposite direction. Then your blood would flow backwards. This in turn would cause you to walk, talk and even think in reverse. You would wake up in the evening and then wait to go to sleep in the morning. You would eat with your butt and poop with your mouth. The film “Memento” would make perfect sense to you. That’s just not natural.
Don’t do R.A. If you see anyone going backwards, report them to your local police or hold an intervention. R.A. spoils lives, but it’s never too late for its effects to be… Reversed.

if I drink reversic acid, and I want it to be reversed, do I drink more reversic acid?

No, Reversic Acid has a quantum spin of 180 degrees, but it’s quantumly cumulative instead of quantumly progressive. You can’t complete a full quantum circle without Antireversic acid, which will turn you back quantum-clockwise (Reversic Acid being quantum-counter-clockwise).
Note also that by using the word quantum a lot, this post becomes exactly as legitimate as the works of Deepak Chopra.

Indie or hobbyist, if you’re a game developer with a Tumblr blog dedicated to your process and progress, reblog this!
You will be added to The Game Developer Network.
You can read about the network here.
If you have a Twitter you’d like linked, please include that in your reblog!
You can also be added to the directory by messaging me.
** Remember: This is only for game developers.
Basically, my reason for creating this is so that gamedevs on Tumblr can find fellow gamedevs. It’s kind of like an easy to navigate directory to find and connect with people who are also working on games.
Don’t be scared to ask or reblog! This is for all game developers on Tumblr! Really. Don’t feel lame. Help me help you~

First post!

Hi there.

"Ping Pong Boys" is a manga/anime parody about a 15 year old boy and his friends who want to master the art of ping pong in a hopeless world.

That’s what this blog is gonna be all about. Character designs are first out, and I’m open to all suggestions! Several designs are already made and put on schedule, so please follow (if you feel like it). And the main character has been posted, so just visit to check it out! :D 

Get ready for PING! PONG! BOYS!!!

Game competition

I participated in a competition where the goal was to make a prototype of a game in 10 days. This is what I came up with if anyone’s interested. It’s a puzzle platformer in which you control a beam that starts off cold and becomes hotter the further it goes. (The game is in Norwegian, but here are at least the controls in english: WASD to move, jump and enter doors. Hold LMB to shoot, hold RMB to view room. R to restart room.)

MULAN WAS A KYOSHI WARRIOR

I always wondered how she pulled that move off without cutting off her hand and when I realized it was impossible, I was devastated. 

No that isn’t impossible. She twists the fan. She doesn’t just pull down. It is feasible, difficult, but not impossible.

Wanna talk impossible? How about how he just JUMPED THROUGH A FUCKING ROOF.

This is one of our several attempts of boss music. The music will have a special role, when coming to how the boss fight will develop. Also, this is not the final version. We plan on upgrading the music eventually, so consider this a draft for now. Without further ado, this is the castle theme, boss version.
