Cybertruck Prototype vs Final Production Version - What Changed?

In 2019 I started making a 3D model of the Tesla Cybertruck prototype version in Blender. Four years later, in 2023, Elon Musk finally released the production version of the Cybertruck . Since I've studied every millimeter of the prototype version to be able to make the 3D model I thought it would be interesting to make a comparison of how much changed during the four years. Exterior Front bumper. The black front bumper has become bigger and smoother, most likely to improve the aerodynamics of the vehicle. They also added a mudguard for the front and rear wheels attached to it. Front window. Like the front bumper has become smoother to improve aerodynamics, so has the front window which is now rounded - it used to be completely flat (To be honest I think this is the case anyway - it is not rounded much to make it super visible). Wheels. The wheels are roughly the same as the prototype vehicle wheels - they added som threads to the side of the wheel. I thought t...

Explaining the Hybrid A Star pathfinding algorithm for selfdriving cars

Let's say you are standing somewhere in a room and would like to find the shortest path to a goal. You can see a few obstacles, such as a table, that you would like to avoid. The easiest way to solve the problem (if you are a computer) is to divide the room into many small squares (cells) and then use the common A* (A Star) search algorithm to find the shortest path. But what if you are a car and can't turn around 360 degrees like a human can, then you have a problem! Well, at least until you learn the Hybrid A Star search algorithm . With that algorithm you will be able to find a drivable path to the goal. The reason I wanted to learn the Hybrid A* algorithm was that I took a class in self-driving cars, where the teacher showed a really cool video with a car that drove around in a maze until it found the goal: The problem was that the teacher didn't explain the Hybrid A* algorithm - he just explained the classic A* algorithm , so I had to figure it out on my own...

Bing Image Creator AI: An overview of art styles and materials you can use

The search engine Microsoft Bing has a new tool called Image Creator . This tool lets you create images from text by using an AI system called DALL·E 2 from OpenAI . If you want a superchihuahua with a red cape, just type "superchihuahua with a red cape" and you get four images in just a matter of seconds (the more images you generate the longer it will take unless you pay Microsoft some money). No-one took a photo of exactly this chihuahua dressed in a red cape - it doesn't exist in real life - it was generated by the Artificial Intelligence. Art styles The Image Creator tool can also generate images with a specific art style, such as watercolor or anime. But there's not an overview of which art styles are available, so I thought I would try a few of them and show the result here. To get a specific art style, you type "superchihuahua with a red cape, anime art style" so it understands which art style to use. The AI is smart when it comes to generate cool i...

How to implement colormaps like Rainbow and Viridis in code

I've been working hard on making my very own digital wind tunnel in the Unity game engine. It's based on a tutorial from the YouTube series 10 Minute Physics called "How to write an Eulerian Fluid Simulator with 200 lines of code." I translated the code from JavaScript to C#, and I open sourced the implementation here: Ten Minute Physics in Unity. To simulate any fluid you need to study the Navier-Stokes equations . These are very hard to solve. In fact so hard they are a part of the Millennium Prize Problems where you can win a million dollars if you gain some insight while solving them. Therefore you need to simplify them. But even though they are simplified you can still see the vortex shedding that's happening in real wind tunnels if you put a cylinder in them. I thought this was really cool because the simulation part is just 200 lines of code running at 70 fps on the CPU. Common colormaps I wanted to improve the wind tunnel by making it more realistic...

The miniature statues of Stockholm

Stockholm, Sweden is covered in statues and sculptures. Some are big and some are small. But some are even smaller than small - they are tiny and thus very difficult to find. This will be an overview of the miniature statues I've found. Karlsson on the roof You can find this sculpture on Fjällgatan , which is a popular area to go to if you visit the Södermalm area because they view over Stockholm from Fjällgatan is very nice. This statue was the hardest to find information of. I tried to Google, but nothing was found. You can see that he's playing a VR game so I thought he was a tribute to all the famous game companies with offices on Södermalm. But after researching another mini statue where I stalked the artists on his Instagram I realized Kolodko Mihály had created him. And the character is no one else than the famous Astrid Lindgren character Karlsson on the roof . If you look closely on the statue's back you can see he has a little propeller which real Karlsson i...
