Thanks! Happy new year!

Incredible stuff! You did hint at a fast raytracer. I was wondering if it meant a real-time raytracer. With POV-Ray, even a simple scene at 80*50 without all the details enabled takes a minute or two. To get someting in real-time would imply a couple of orders of magnitude speed-up. For sure this ca...

offtopic question: does Atari STe have dual playfields like Amiga?

No, the STE doesn't have a dual playfields mode.

Good! I'm afraid to ask but is the pad button assignment ok? It should be A for fire and B for bombs, isn't it? You can also exchange those buttons in the in game options so does that work as well? Yes, the jag pad buttons assignment is correct. Default is A for fire and B for bombs. The exchange o...

I just tried it. It's really fun, incredible sprite action!
I'm not very good at shoot them up, my best score is 392572.

I tested this public build on my Falcon. No lightmap weirdness, it runs fine!

Ah, my sentence was not very clear: I tried your new public build of Q2 engine in Hatari 1.8.0.
Tonight I'll try with my Falcon...

I briefly tested the new public built in Hatari.

Lightmaps seem to be a bit messed up. Here is a screenshot from ikdm4 in color mode.


It also happens in mono mode. It seems to me that something doesn't use the proper dimensions.

This stuff is mesmerizing. Great work Anima!

I tested the engine on a regular 14MB Falcon.
It runs at about the same speed than the previous version I tried but with a lot less noticeable texture popping. That week-end was well spent!
The outdoor lighting in IKDM4 is really nice, with its soft shadows.

I briefly tried this version on Hatari 1.8 this morning and it works fine.
The surface caching is definitively improved, good job!
I'll try it on my real Falcon tonight.

Thanks guys for the compliments.
I have no specific plans for the moment, though doing a small game would be cool.

I'm using the Windows version of Hatari. The command "hatari_falcon.exe --help" doesn't do anything. With the command "hatari_falcon.exe -W" I get in both cases: "Hatari v1.8.0, compiled on: Jul 30 2014, 00:55:03" It is the same executable, I compared with Winmerge and it tells me that both files ar...

I made an additional test: I force the instruction cache ON. In this case, the bug doesn't happen anymore. The test program gives 14470 ms in both my Hatari installations. I attached both the test program and the voxel program that forces the instruction cache. Before that, only the instruction cach...

Here are a few results of the CPU side code running 100 times. - Hatari 1.8 in my dev setup (no bug): 14470 ms - Hatari 1.8 in my emulators folder (bug): 20375 ms - Real Falcon030 (no bug): 10820 ms It is strange that I get different results between the Hatari installations. Executables are identica...

so Jaguar is only twice as fast as Falcon with voxels (do you use same resolution on Jaguar)? is there any time left for game logic and sprites on Falcon? I use the same resolution on the Jaguar. However there is a small game running around in the Jaguar version. The game logic would probably not s...

Do you have fast RAM? Which FPU version you have? Any other modifications to stock Falcon? The Falcon doesn't have any fast RAM. It's a 14 MB Falcon with 68882 FPU and 4GB CF. It doesn't have any accelerator. The FPU isn't used in voxel drawing loop. Maybe you could at some point do a version of yo...

When one goes up, horizon looks weird though as hills get clipped. Ah! Did you run into this weird bug? horizonbug.jpg This is very strange. It doesn't occur with the Hatari install I have with my dev tools, but it happens with the other Hatari install, in my "emulators" folder. Both installations ...

Hello, here is a DSP based voxel engine I made in the past few weeks. It runs in 160x200 on a VGA monitor only, the Falcon doesn't do 160x200 on a RGB in hardware. It's adapted from an engine I made for the Jaguar. It typically runs in 9~10 fps. The Jaguar version is about twice as fast (~18 fps wit...

Interesting question! I'd like to give it a go... So with hindsight I think the following changes would have made a more balanced machine: - CPU, BUS at 20 MHz and DSP at 40 MHz. Thanks to various accelerators we now know that the Falcon can be overclocked to 25/50MHz with little modification. At 20...

I was not aware of this tool! Thanks! I will try it out tonight.

Hello, I'm trying to set up 160x200 True Color mode on VGA but I'm not successful. I start from 320x240 TC, which I set using XBIOS function VSETMODE. To set up VIDEL registers, I'm using the explanations from this page: http://mikro.naprvyraz.sk/docs/mikro/videl.html Setting 200 lines is easy, I ju...

Source engine coming to life on Falcon... that's a red letter day!

Silliness aside, I like the experimentation you're doing. We're in completely uncharted territory here.

8-bit computers have been pushed quite far in modern days. It's nice to see people also pushing the Falcon...

Really the adaptation of the Quake2 engine on Falcon has unforeseen consequences!

Thank you guys for the appreciation!
