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.
Tried some (Integer) Speedtest, some people asked me about. Of course I’m also interested if my feeling (double 060/50 speed). I used some code from Benchmarks Game. Especially the tests: fannkuch 10 and BinaryTree 15. (68060/50Mhz= A1200 with Blizzard 1260, MorphOS = MacMini 1.4Ghz, UAE/AROS/Linux = Athlon FX 8120 3.16 Ghz)
Speed rel. to 060
Speed rel. to 060
MorphOS 68k emul
So my feeling was more or less right, it’s around double speed to 060, so it’s a nice step but far far away from UAE. More interesting for me would be FPU processing but at this point the comparison would be very dramatic and a little bit unfair because Vampire still have no FPU support (even it’s everywhere announced, but seems even next version will not have FPU).
I bought a neat eat toy for me. An A600 already equipped with an Vampire processor card. A Vampire is an FPGA based CPU card for Amiga 500 and Amiga 600. A while ago I thought already about to buy a Vampire card. The delivery times for it are very uncertain and seems in the order of 6 Month. I even would need to buy an A600 first, I was really to lazy to do such step with uncertain future. But I found an ready to use one one ebay. Maybe a little bit more expensive but thats fine by me, still much cheaper than a 68060 or PPC card. 😉 The capacitors are exchanged but the audio sounds strange, but not a big problem for me. Mainly I’m not interested in the speed but but in the GFX Card which comes with the FPGA on Vampire. Its the only way to get a 24bit GFX card into a keyboard Amiga (except the very seldom BVision for A1200). Of course my for me very interesting if freepascal and it’s programs work with it and good news on this side, it’s working nicely. The only problem (like on my A1200) is the slow harddisk which makes it much slower then UAE but as I read the next firmware should improve that a lot. Of course a screenshot (done with a screenshot program I wrote in FP-IDE directly on my A1200 some weeks before)
Didn’t have much time today, so I only show a cute little program to learn typing, out of the box compiled for AROS TappyTux, also with Mathematics. still not perfect, needs a little bit work, (sometimes the text is outside), it throws 2 hammers and so on.. but even so very neat.
Playing a little bit with loading routines for vector formats and found the amazing fpvector package. It contains also a nice test program to test loading of files. It works already very nice loading of .svg and .dxf Files. For example .odg files does not work some string to float problem. Also the drawing works rather nicely but also shows some problems with the filled polygons. Worth to try to compare with the Linux version.
Still playing with raytracing (so 3D calculations without GL or so) and other 3D Stuff. Magorium converted a nice little raytracing program from C to Pascal. It creates a random scene and calculate it with high precision. It makes a nice pictures. It is using SDL for display and threading, it seems the SDL Threads do not work, so I changed that to use Pascal Threads and now it is working nicely. Again a nice program for SMP 😛 already ready to use multiple threads (at Linux it runs fine with 8 Threads)
After long time I did again a little bit raytracing stuff, magorium found some source, I reviewed some of my old sources. I would be a perfect thing for the coming AROS SMP, ok I guess it will not appear so soon but it’s really a nice thing.
Notice the multicolor shadows and the multiple refelections.
I never worked with SDL before so I searched for a little tutorial for it and came across a YT video showing SDL game making with freepascal YouTube Link.
I tested the source and applied the special changes for AROS (basically to initialize the SDL and other link libs) and it works really a nice tiny game. I will look more to source to understand the SDL behind it. But first of course a little video
