MUIMapparium is an alternative implementation of Mapparium using directly MUI/Zune instead of LCL.

This version is much faster especially on 68k Amiga. It still needs an RTG card but a non_FPU version is included, but if it is too slow (especially with tracks and routes showing) do not blame me, buy a FPU. On the long run MUIMapparium will replace the Mapparium, at the moment it does not have the same features (but rather close)

I decided to release the next Version of MUIMapparium even not all features are finished as I planed just to get the bugfixes out. Routes (calculated directions) can be loaded from GPX and showed on map. But I did not implement the route finding and direction command showing until now. Especially the Track curve plot was still very buggy, and of course I described in a previous blog post the pixel to position calculation which is now much better, much more precise but also much slower than before, with FPU it does not make big difference, but with SoftFloat not really funny. Routes and Tracks are now pre-calculated for the current zoom level. If the zoom level is very small and the track therefore not really good to see, only some pixels wide, it does only paint some points of it, which makes the overviews much faster. Still, with SoftFPU on 68k it still will be too slow if you have some Tracks/Routes. The drawing of Tracks/Marker/Routes can be completely switched off in Menu or buy a FPU πŸ™‚ The package for Amiga68k does contain a FPU and Non-FPU.
I also created a little GPX file with a Track, some Markers and a Route to test the features. (Even you can use any GPX/KML/KMZ/FIT File you can find on the Internet as well)

  • Bugfix: imperial units
  • Bugfix: key mapping
  • Bugfix: 2nd track curve drawing
  • Bugfix: Date/Time loading from GPX,KML,KMZ files
  • Level of Detail for Tracks
  • Precalculation of Trackpositions (Speed optimization for NonFPU systems)
  • Route drawing
  • Marker in Plot, shows also a marker in the Track
  • Turn off Marker, Track and Route drawing via Menu
  • Define Directory for Images via ToolTypes: e.g. DATAPATH=DH1:TmpDir
  • Change find IP to (old one is too slow currently)
  • FPU Version for 68k

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.

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 πŸ˜‰

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 to try

Posted by ALB42 on 22. April 20179 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)

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.

Unify ASL

Posted by ALB42 on 21. August 2017No Comments

I checked the ASL.library units of MorphOS and Amiga 68k against the official C includes of the SDKs. Especially the TFileRequester structure was always a little bit trouble because the old Amiga asl unit still used the old field names rf_* but from V38 of the Library this fields are all names fr_* and some other tiny dame differences (e.g. Dir vs. Drawer). In AROS and AmigaOS4 I only added the newer names because here I do not have any “old” code. This resulted in a big inconsistency between the platforms and need ifdef’s in the final programs. To prevent a direct breakage of the existing sources (e.g. LCL, MUIMapparium) Amiga and MorphOS have both field names in the structure (as case). The aim will be to remove that ifdef’s from the sources.

More colors

Posted by ALB42 on 20. August 2017No Comments

Due to user wishes one can now change the color of each track and route individually, which is also saved to the GPX File. Routes and Tracks in GPX have an extension area where you can add own properties without violating the GPX format, which is very nice. The Routes and Track property window have now a Color Button next to the Name to choose the color of the feature (you have to save that before the change is visible in the map).
In principle it would be nice to have the color next to the name in the Track/Route List as a little colored square (like I did for track plot axes). But I’m not sure if and how that is possible at all for such a list, without creating a selfdrawn one.
Besides that I implemented that MUIMapparium remembers the position and open status of the Statistics window, seems some user like to keep it always open to observe the loading status or something like this.

Vampire FPU emulation

Posted by ALB42 on 29. Juli 20172 Comments

The very first version of the SoftFPU called femu 0.1 is released and of course I want to try how good (and how fast) it works. It is the first version so no one should expect wonders. It comes in three versions, 030, 040 and 080 (why there is no 020?). In principle I wanted to try all of them but only the 080 Version works on the Vampire. the 030 Version crashes directly, the 040 crashes on first FPU command. So I have stay with the 080 Version.
First again my Mandelbrot program. (sadly the picture output does not work currently, not big endian compatbile πŸ˜‰ so I can not check if the result is ok)

Mandelbrot results (Runtimes, shorter is better)

Test 68060/50 MHz FPU 68060/50Mhz SoftFPU Vampire SoftFPU 68030 68882/50 Mhz FPU 68030 SoftFPU Vampire Femu 0.10
Mandelbrot single precision 0.12 s 9.53 s 3.81 s 2.14 s 38.03 s 11.14 s
Mandelbrot double precision 0.15 s 23.72 s 13.37 s 2.31 s 71.87 s 10.31 s

Thats already rather interesting, it seems the femu calculates everything in double, which makes sense because the FPU always use extended. There was a hint already in the manual that femu needs the double precision math libraries from the system. It seems that femu is just a wrapper to guide the TRAPs to the libraries. Not a bad idea actually. In double it’s even a little bit faster than the FPC SoftFPU, not bad, as guessed in the FPC SoftFPU is a lot of optimization potential πŸ˜‰

Next the Scimark test:

SciMark2 results (MFlops, higher is better)

Vampire V600 V2+ 128 MB FPU Code femu 0.10
Mininum running time = 2.00 seconds Composite Score MFlops: 0.08 FFT Mflops: 0.04 (N=1024) SOR Mflops: 0.12 (100 x 100) MonteCarlo: Mflops: 0.05 Sparse matmult Mflops: 0.09 (N=1000, nz=5000) LU Mflops: 0.09 (M=100, N=100)

Vampire V600 V2+ 128 MB SoftFPU code
Mininum running time = 2.00 seconds Composite Score MFlops: 0.06 FFT Mflops: 0.03 (N=1024) SOR Mflops: 0.12 (100 x 100) MonteCarlo: Mflops: 0.03 Sparse matmult Mflops: 0.08 (N=1000, nz=5000) LU Mflops: 0.02 (M=100, N=100)

This SciMark tests are usually done in Double precision so we see the same trend as in the Mandelbrot. It’s very nice that this tests run without any problems already kudos to the coder, it works.

To check for more FPU commands I took out my real time raytracer (ok on Amiga not that real time anymore :-P) changed that to a saving routine of a single picture and compiled for FPU and SoftFPU. It works and the picture looks very nice, as it should be:

TraceRay FPU on Vampire with femu 0.10

As visible in the picture it needed 730 s to render that picture (as I said, not really realtime) with fpc SoftFPU it needs 280s the 68030/68882/50 Mhz needs 224 s. (sidemark on my AROS i386 box that image needs 0.2 s) and for all cases the picture looks good. The femu does what it promised, not actually very fast but reliable. A little bit disturbing of course is the freezing mouse, when the TRAPs appear. But here the coder of femu can’t do anything, as far as I understood he works closely together with the Vampire developer, so maybe he get a faster (or even not-) TRAP mechanism for the emulation in a later Vampire Firmware.
At the moment I still would prefer to use FPCs SoftFPU for MUIMapparium because there the Mouse will not freeze so the GUI feels more snappy.
