 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Here is an initial release of MandelbrotEXP16 V1.0 This new program calculates the "Normalized partial iteration" (Yikes) for each pixel for smooth color transitions. I don't see this program as an "upgrade" or "replacement" for the 8 bit color Mandelbrot Explorer, It's a completely different animal in my opinion although it shares most of the user-interface with the other program. I am partially color-blind and I do like the contrast and visual textures provided by the 8bit colors in the other version. If you have better color perception than mine, you may have a greater appreciation for the smooth color transitions in this new version. In any case, I think there is a place for both versions. Notes: I changed the aspect ratio to display better on "normal" monitors. Rolling colors is disabled for now, I need to figure out an efficient way to roll 16bit colors. CSUB? The 'P' key will now display a color mapping help screen while the 'M' key is a shortcut to allow you to change the color mapping without the separate screen. The rendering time is only slightly slower due to the fact that the additional calculation only takes place once each pixel and not each iteration. I am working on some final tweaks that may improve performance (rendering time) and then I will post the 'C' source code and sample files etc. Let me know what you think about the smooth colors!

Sasquatch, I love it! Sorry I've been awol...but I've been busy with life and hobbies #1 & #2!  Everything works as expected and the smooth transitions on coloring are perfect! I'll try and test all functions out later today! Great job! Steve |

Perfect time 'waster'! Everything works. I added a line to play a modfile while roaming around, looks like 8000 samplerate is tolerable up to 512 iterations. I like at least 256 iterations. I wonder if there is any possibility of improving this...some tweak on the csub side? In about a month, I may have some time to do something productive with this. Steve |

Thanks for the feedback Steve! I had been so focused on keyboard problems and rendering performance that I hadn't even thought about music in the background. Try this test version when you have a little "time to waste" LOL It renders just a bit slower, but gives MMBasic more time to do it's background processing. It may help with your mod file at greater iteration depth. I also included some updated sample files with nice color mapping for the 16bit version in the .zip file. I'm still working on the color mapping, it works ok, but I think it could be better. MandelbrotEXP16.zip -Carl |

Sasquatch, that did the trick! Works well at 256 iterations and 22050 sample rate. I think it's even okay at 44100, maybe just a slight stutter on occasion, but since my ear detects no difference between 22050 and 44100, I'll keep it lower. If I can find some time here in the next few days, I'll work on a routine to: play music?, ask for a directory to build a play list. Steve |

Sounds great! I had also thought about a "slideshow" mode that would cycle through the images stored as .dat files displaying each one for 10 seconds or something like that. If combined with music that would be even better. -Carl |

Sasquatch, Here is a modification to the .bas file, that adds the ability to play modfiles. I ask for a modfile directory or answer 'no' for no music. It will play modfiles for 5 minutes (a reasonable time, given you don't know when a modfile ends) then change to the next file and loop around, I use setticks for this. You can also press the Wii Classic R button or the 'N' key to change to the next file. I've also added more functions for the Wii Classic and changed the defaults for depth and hue...something 'pretty'  . I'm not sure of your revision method, changed it to version 1.0U from 1.0T. I would send some modfiles, but am unsure of copyright status...they're easy enough to get hold of. I could also add the same ability for .mp3, but for me at least, modfiles are more in keeping with the 'retro-ness' of the platform!Steve MandelbrotEXP16u.zip |

Thanks Yock! I'll check it out later today. I plan to work on a "Slideshow" mode where it will cycle through the .dat files displaying (rendering) each one in sequence. Combined with the music this should be really cool. And thanks for the help with the default colors, My color perception is sub-standard. Edited 2020-09-30 06:29 by Sasquatch -Carl |

Seems to work great! I'll need to find more MOD files to give it a proper testing. What would you think about using the 'N' key to toggle music on/off and the < > (less than,greater than) to skip to the previous and next track? When using the 'N' key to toggle the music on it would prompt for the directory? -Carl |

Here is the file with the requested changes. For now I have removed auto track changing, that will give me something to do tomorrow!  I'm also thinking about some type of status line, perhaps by changing the vertical resolution or even a 'peek a boo' type that would be pulled from offscreen...but that's going to take a bit of study on my part!Steve MandelbrotEXP16u.zip |

Well, with the way you've got this setup, the status line was pretty easy to implement, nothing fancy needed. I've also re-enabled Roll Colors, it just increments the multiplier by 10 up to the upper limit, then drops to the lower limit, etc.. works okay for me. The 'm' command is still available to set the hue and/or multiplier independently. Other things I'm thinking about are, cursor visibility, sometimes it gets tough to see...not a big deal...and I don't have an idea at the moment to address it. Last thing would be to spiff up the status line, where the text would overlay the plot...see thru....that would take blitting I think...and study, as I haven't messed with blitting yet.. I can upload if you'd like to see these changes, or....not sure if you're still looking to do any more with this. Steve |

Hey Steve, Did you get the auto track changing for the MOD files working again? When you are done tinkering upload your latest changes and I'll merge it with anything I've changed since the last upload. I think I'm about done, unless I get some inspiration for something more LOL. -Carl |

Here is V1.1 of the MandelbrotEXP16 program. Yock1960 added Modfile capability and a new status line. The cursor has been changed to give more contrast against lighter backgrounds. Sample .Dat files have been added to the .zip 'C' source for the Mandelbrot16 CSUB has been added to the .zip Due to copyright concerns, you will need to supply the .MOD files to your preference. There seems to be several websites where .MOD files can be freely downloaded but I don't have time to research potential copyright issues. MandelbrotEXP16.zip -Carl |

Carl, I think this is the last from me (finally!) A slight, subtle change to the status line. I tried the idea of transparent text background and apart from having visibility issues, similar to the cursor when in 'busy' areas (good fix on the cursor BTW), it really slowed down moving the cursor. Perhaps this could be done differently/improved, but for now, I don't think it's worth pursuing. Also fixed a minor bug with the status line. Other changes are: 1) new command 'T' for rolling Depth. It can be interesting to see the changes, goes from current through 256, 16-256 total range...probably enough for most people. 2) added some parameters to the load/save list and make a check for the existence of a file named default.dat, which will autoload if it exists. Check this file against your latest. I just hand made the cursor changes to my last, so I may have missed anything else you changed that I didn't see! Steve MandelbrotEXP16w.zip |

Yes, I made a number of small tweaks other than the cursor. For example no need to render the entire image when changing the MOD settings, just copy from Page 1 is much quicker. I suggest you use a file compare program. I use WinMerge, as the name suggests it only works on Windows but there are many others for Mac, Linux etc. They will show two files side by side on the screen highlighting any differences and allow you to move lines or blocks of text (code) from one file to the other. -Carl |

Okay, did the file compare/resolution, merged the files. There are a few things I left different, either because they were trivial or perhaps my recent changes has made it unnecessary. For example in the next or previous mod file, you do a +2, where I do a +1...seems to work, I think this may have been a bug I fixed. Anyway, changes: 1) Roll Depth - T command, same as roll colors, except... 2) from the startup help screen, pressing any key except TAB, loads default.dat, which is set to the program defaults, but could be changed if the user wanted. Pressing TAB loads user.dat...if it exists. After initial startup the file command is still available. 3) 'Blinged' up the status line! Some color and if autoplay is enabled, the text 'autoplay on' starts out all green, but as the 300 second count increases, the text changes red...as a visual indicator to when the next track will start. The faster updating of the status line is great! Steve MandelbrotEXP16wa.zip |

I finally got around to trying this 16 bit version of Mandelbrot explorer. It works fantastic! About the only change I might make is to display the full numerical resolution of the coordinates. Great work Sasquatch and yock1960! Although I didn't try the MOD files or extra commands. I/O/D and arrow keys gets me around. The default colours look great. The rest is too much to remember. ;-) Visit Vegipete's *Mite Library for cool programs. |

So, I restricted the coordinates display to save space, trying to keep to a single line for the status line. For myself, the coordinates are not strictly important, since I'm driving around graphically. I can work on some kind of toggle, either dropping some info, the modfile title for instance, to expand the coordinates or adding a second line to the status...seeing how it looks...or something different...if I get some inspiration! Sasquatch has done a great job with this and it's been fun adding a few bits and pieces! It should help me when I start something 'new'...new to this platform anyway! Steve |
