I have updated my old Anagram Generator app for new Android devices.
Lexigram and anagram searching.
Word searching using wild card characters. Useful for crosswords and Scrabble.
Rhyming. Search for words that rhyme with a sepecified word. Good for song writers and poets.
Dictionaries supported are Dutch, English, French, German, Italian and Spanish.
Download Anagram Generator from the Google Play Store here. 100% free and 100% ad free. No device access required for use.
After some updates for the latest Android versions I have now released the latest version of ADDLED to the Play Store. ADDLED is 100% free and ad free.
The aim is to find a set of numbers that add up to a total value. Initially the levels are simple with just sums using positive numbers, but later levels give larger grid sizes and negatives, multiplication and division.
As the difficulty increases there are more strategies to implement to get through levels.
The levels are quick enough to fill in a few minutes when you have some spare time. There are 5000 total levels to keep you more than occupied.
If you think this is your sort of puzzle game, download ADDLED through the Google Play Store.
I have updated my Visions of Chaos for Android application to version 1.19. Click here to go directly to the Google Play Store page.
New features/fixes include;
1. Added more color palettes
2. Added more sample GLES shaders
3. Added Delete option to remove shaders that are incompatible with device
4. Fixed instabilities with pinch zooming
5. Fixed out of index bug that sometimes occurred with Buffalo Fractals
6. Fixed spinners’ dropdown text colors so they are more visible
7. Fixed bug in GLES shaders that date.w was passed as current second rather than seconds since midnight
I do recommend using a new high end Android phone or tablet. The shaders can crash older devices and general performance can be frustratingly slow on old phones.
All of the images on my Instagram gallery were created using the app.
Today marks 10 years since I started my YouTube channel.
Back then a video with a resolution of 240p (426×240 pixels) like the following was considered OK.
These days I can upload a 4K video (nine times the vertical and horizontal resolution of that 240p video) and once YouTube puts it through their internal conversion routines it will usually come out looking excellent.
Mitsuba renderer is a free 3D rendering engine created by Wenzel Jakob that creates realistic images like the following.
Wenzel is one of the co-authors of the seminal PBRT book, so he knows his stuff. Mitsuba uses an XML file format for the scene files that you can pass to the renderer as a command line parameter. This makes it easy for me to build a compatible XML file and get Mitsuba to render it each frame.
Here are some sample 4K images created with Visions of Chaos and rendered with Mitsuba using the constant lighting model. Constant lighting means that light is simulated hitting surfaces from all directions evenly. This means there are no shadows, but crevices within structures and corners are shaded darker because of ambient occlusion.
Using Mitsuba really gives clean, nicely shaded results and the examples above only using the most basic Mitsuba lighting/material setups. Mitsuba has handled the multi-gigabyte sized scene files with millions of spheres and/or cubes scenes with ease. All the end user needs to do is download/unzip Mitsuba and point Visions of Chaos to the main executable.
The latest version of Visions of Chaos now includes both a 32-bit and a 64-bit version. You will need to have a 64-bit version of Windows to use the 64-bit version, but if you still use a 32-bit version of Windows then the 32-bit version of Visions of Chaos will continue to work for you. If you are not sure what “bitness” (bititude?) your Windows is, press Windows-Pause and look next to “System type” on the dialog that appears. Both versions are included with the same install exe to avoid confusion and the 64-bit version only installs if you are running 64-bit Windows.
The main advantage of the 64-bit version over the 32-bit is that there is no longer a 3 GB memory limit. As screen sizes have increased the amount of memory that Visions of Chaos requires to render some of its modes at these higher resolutions was hitting the 32 bit application memory limits. 64-bit Visions of Chaos can now use as much memory as you have physically installed in your PC.
Back in September 2010 I was experimenting with Lattice Boltzmann Method (LBM) fluid flows.
At that time I managed to translate some (probably Fortran) LBM source code provided by the now defunct “LB Method” website (here is how LB Method looked around that time). The algorithms worked and did give me some nice results, but there were problems like lack of detail and pulsating colors due to my display routines scaling minimum and maximum velocities to a color palette.
Yesterday I was looking around for some new LBM source code and found Daniel Schroeder‘s LBM page here. Daniel graciously shares the source code for his applet so I was able to convert his main LBM algorithms into something I could use in Visions of Chaos. Many thanks Dan!
Using Dan’s code/algorithms was much faster than my older code. It also allows me to render much more finer detailed fluids without causing the system to blow out. I can push the simulation parameters further. Dan’s method of coloring solved the pulsing colors issue my older code had and includes a really nice way of visualizing the “curl” of the flowing fluid. Tracer particles are also used to follow the velocity of the underlying fluid to give another way of visualizing the fluid flow. Once particles leave the right side of the screen they are buffered up until they fill up and can be reinjected to the left side of the flow. Tracer particles help seeing the vortices easier than shading alone.
With less memory requirements (another plus from Dan’s code) I was able to render some nice 4K resolution LBM flows. This movie must be watched at 4K if possible as the compression of lower resolutions cannot handle displaying the tracer particles.
The new LBM code is now included with Visions of Chaos.
