Any Hollywood programmers here? Could Hollywood be used to code something more complex like LightWave 3D 5.x for example or is that beyond what it can do? I don't know so just asking.

it is certainly too slow for highend graphic applications. I do not think the results would be very fun. But perhaps others with more Hollywood experience can say more about it.

We need a Hollywood Application list.

I noticed in this demo that there is multiple layers.
How is this?

nice demo. But demos are all coded in assembler and not in a high level language. I do not know if that is possible (supported) by any of the languages. But a really good effect.

@Olaf

Could you say more about amiblitz 3D support via stormmesa?
Perhaps post a basic example listing?

Does amiblitz support   .library calls?  so allowing to use microbe3d.library that is (imho) more efficient

I am not a expert (yet) but i know that there is a example that is using stormmesa and it is full supported

I found a explanation from "Wanderer" Thilo Köhler that MESA is full integrated

Source-Code (screenshot) from example 3d_cube

How is amiblitz with gui programming?

Outside of Hollywood, how could some one make software that can be relatively easy to port from platform to platform?


Use an OS-agnostic APU like SDL, QT, GTK, WxWidgets, etc. in C, C++, etc. If we had Java JVM, that could be another option.

My favorite is WxWidgets, as one of the mian goals wiht it is to make an app appear and behave as an OS-native one. Other of these APIs may look foreign on your OS of choice, such as a QT app always looking like a QT app, regardless of what OS it is running on. WxWidgets apps intend to look like MS Windows app on MS Windows, or look like an OSX app on OSX, etc... I'm really hoping we get a WxWidets port to AmigaOS and -alikes. If only I had free time...

Is there any reason why software can not be made for Amiga os anymore?


No. I just bought Stormc4 a few days ago...

You have to design your code to be portable. Take a look at BasiliskII for example, it was designed with portability in mind. Split the parts that are platform specific, you'll probably gain readability too. Many linux apps are just "hardcoded" posix apps not easily portable to non posix systems (that's why Cygwin exists for Linux and ixemul for Amiga). Take as an example SheepShaver, the latest maintainer posixified all the code making it non-portable to non-posix platforms.

If you decide to learn C amiga is a good platform for that too, the most important part is that you learn to use pointers properly, otherwise there's no much sense in using C.

If you decide to develop games you could use SDL library, it won't be fun to use on miggies. You can create your own functions for drawing sprites, backgrounds... and once SDL works then you can try to make an OCS/AGA/CGX version (it won't be easy but will be more effective than embedding SDL calls everywhere in your code).

If you decide to create an app try to split the logic part from the GUI and the storage one. You may have to rewrite small parts of storage part for taking care of endianness and you will have to rewrite GUI part for sure but it's not such a big problem, there are usually tools for that.

On Amiga systems the GUI of choice would be MUI as it's supported on all systems and for other OSes you can choose GTK, QT... keep in mind that these alien GUIs run awfully on Amiga if they run at all.

Great.
I have studied C and C++ and got into using pointers.
I have a blog on pointers, not much is there.

I see for the most part what you are saying about organising your code for portability.
I would like to bring more programmers to the Amiga. The ability to bring code from other platforms seems to be a must these days.

Would Amigans be willing to buy software for a dollar or 99 cents?
