MUIMapparium 0.4

Posted by ALB42 on 26. Mai 2017No Comments

Working more on the Trackview to show the height and speed track, added a simple Popup Menu and a Data Reader. In the beginning I wanted to use the Bubble function of MUI to show the coordinates, but it flickers like hell if you move it over the map (because you have to destroy and recreate every time) and it makes very bad redrawing errors. On AROS for example when the bubble is over an other part of the window, the background behind it will not repaint, when the bubble disappear. On Amiga the background of the window is visible on the edges instead of my curve background. Also added a fine grid for better visibility of Values and heights, still fixed but maybe later can be disabled via menu.

I implemented a on screen (on-map) menu for zooming and to show the side panel, so do not need use the menu. I did that already for Mapparium but there only released for the special ARM version. There is also a key control available, the + and – keys can be used for zooms and cursor keys for movement.

I guess it will need one or two more version for MUIMapparium to reach the features of Mapparium but I guess it will be MUIMapparium will takes the Mapparium place (and Name) in the end.

MUIMapparium 0.3

Activated the localization for MUIMapparium currently only for english and german (of course ;-)) implemented also the local library unit for AmigaOS4 so localization is available on all platforms.
I also activated the AREXX interface currently only two commands are implemented: goto lat lon [zoom] to jump to a position and addwaypoint lat lon “Name” to create a waypoint. The Portname is the same as for Mapparium an example script can be found in rexx folder. The AREXX port does not work for AROS, Zune has no AREXX support currently.
I tried to compile it on AROS64 sadly the program did not work, it just freeze. Little bit strange sometimes it start but crash directly. I tried some other programs on AROS64 and they work rather nicely so why MUIMapparium not. The difference was easy it uses threads, finally I found the solution, the Critical Sections in FreePascal are mapped to SignalSemaphores of Amiga. In contrast to other OS the SignalSemaphores are not just simple pointers but a complicated structure. The given size there was ok for 32 bit Systems but for 64 bit the structure is much bigger. I included it for that release maybe someone want to try it 😉

MUIMapparium 0.2

Had some time to work a little bit on MUIMapparium, mainly implemented way points and tracks including loading and saving, same formats as Mapparium. Due to multiple requests I created a OS4 version again, but I have no way to test it. Still it’s only a very early version of MUIMapparium.

MUIMapparium 0.2 for Amiga

MUIMapparium to try

Posted by ALB42 on 22. April 201711 Comments

Some people ask me to supply a Version of the MUIMapparium presented yesterday. No problem, please just remember it’s heavy work in progress, not much is working currently. In principle only Mapping and searching function, but this is already nicely working on all my available Amigas. Please note the m68k-Amiga Version needs RTG (or it will just crash), OS3.1+, MUI of course and without network it’s not really useful ;-). The Amiga Version works nicely on Vampire A600 (RTG Screen) but should also work with every 68020+ Amiga with graphic card, just a little bit slow perhaps. (FPU is not needed, in contrast to Mapparium)

MUIMapparium on Vampire

Some days vacation, used the evenings in hotel to re implement Mapparium in native MUI and with fpimage for loading the PNG files and Drawing. The Drawing is faster than LCL (the LCL wrapper is huge, already slow) but still rather slow. At last I wrote a own Drawing routine which made it fast enough to start it on a native Amiga with Vampire A600. And it’s nicely usable even without FPU but of course on a RTG Screen.

MUIPlot – a simple function plotter

Posted by ALB42 on 13. November 2018No Comments

I used the function parser for a function plotter before when testing the TAChart for LCL. Now I gave my Plot component I use for MUIMapparium a little bit of reshape and fit it into MUIClass components and created a new function plotter.

I little video to show how it works:

Running on a Amiga 1200 with 68030 50 Mhz and 68882 50 Mhz on a 32 color AGA Screen. For Hex2 the floating point calculation speed is not very important, because it’s just a single function. But for calculating the full curve it needs a little bit more floating point calculations. Therefore a FPU is included. Also you should limit the number of Points to calculate to for example 100. For NG Amiga systems of course you can increase it to higher numbers.

More Track Statistics

Posted by ALB42 on 10. Mai 2018No Comments

When calculating the statistics value for the track export I thought it would be nice to have them for the normal Tracks Properties Window as well and also repaired the color indicator for the right and left axis for MUI (in Zune it worked).

Export smooth tracks

Posted by ALB42 on 6. Mai 2018No Comments

With such a nice weather I drive a little bit more bicycle, therefore the track function of MUIMapparium is more interesting at the moment.
First of course the export I added for the Route also is useful for the track and there even more, because we can print out some additional informations about the track.
Depending on the Program recording the track the data can be very noisy so I added a simple smoothing function.

Vampire Gold 2.8 FPU

Posted by ALB42 on 25. März 20183 Comments

During my vacation two new Versions of Vampire Cores are released. One (2.7.1) only adds more serial numbers so no actual core changes and the second (2.8) has some bugfixes. One Bugfix is called ‘- minor FPU fix’, sadly no more information what that means. I heard the rounding issue is solved and MUIMapparium (FPU-Version) should work now, so let’s try that.

But sadly MUIMappaarium still shows nothing and that is because the rounding issue is still not solved in this core (as you see in the picture), also the the precision problem persists. So I’m not sure what they fixed in this version and what happened with the MUIMapparium fixes they showed before 🙁 More waiting.

Vampire 2.7 FPU

Posted by ALB42 on 3. März 2018No Comments

I just found out you can turn off the FPU with “VCONTROL FP=0” sometimes it work, sometimes not (just crashing, if this because of my sloppy power on the Vampire or just bad timing, who knows). But after it you can start FEmu as with 2.5 and the testcodes work again. Also MUIMapparium FPU Version is working :-D.
In principle that would be the better alternative to the current situation, implement single precision inside the FPGA and trap the rest, which can then be covered by FEmu. Would make Quake and Demos and so on fast, but would not violate the IEEE 754.

In the current situation Amiga (Vampire) is not anymore IEEE 754 compliant. The Double format is now something like 24 bits significant (like IEEE Single) with 11 bits exponent (like IEEE double) because it can still go to 1e308 but the significant precision is much lower as shown before. Also strange if you multiply two big numbers to produce an overflow for example 1e200 * 1e200 in double precision that would give “+Inf” or an exception, but Vampire FPU shows 1.8e+308 (something close to the max Double Value) and you can continue to calculate with that.
