When you port, Swinth, will you do it in BASIC or assembly?
If it is in assembly I would be curious in the code.

I don't think BASIC could handle it..

Glen Bredon wrote the Merlin Assembler, ( AKA Big Mac ), so Swish should be in 6510 Assembler for the C64..

I would love to find the original Swish and Synth Assembler Code, or at least the Machine Language, to see how they work separately..

I "stumbled across it", while looking for something else..

I wonder, sometimes, how come this article wasn't found earlier with Google Searches, but I have to remind myself that with the popularity of Apple ( the company ) today, a simple search for "Apple 2 Double High Res Graphics" is not going to reveal many "relevent" Results...

eBay was (is) pretty bad, when searching for "Apple 2", and getting a Whole Lot of "iPad 2"..

You will get better results if a search is done using the words "vintage" and use "II" instead of the number "2".  This will still pull up a lot of the older Macs but weeds out a lot of the new products.

Not the information I had hoped it contained.

I am looking more for animation and the like.

But this has come up recently and could be

interesting in the near future.

Hi, I'm half of the 6502 Workshop team developing Nox Archaist.  Thanks for the interest in the game.  If you guys have any questions or suggestions about the game feel free to let me know. 

 

Hi-Res Graphics & Animation Using Assembly

Language by Leonard Malkin

 

It is detailed explanation/examples of graphics

for the Apple ][ and also includes Double-HIRes

Graphics.

 

We have a copy of the Malkin book.  I could post some info from it if there are specific pages you'd like to see. Unfortunately I don't have a scan of the entire book. 

 

Here is the table of contents:

Nice to meet you and thanks for chiming in.

If you could post Chapters 14 & 15 that would be great.

I have not thought to add the word "vintage", but I typically use "2", "II" and "][" in searches...

Thanks for the Tip....

I took an article "Sixteen colors and beyond; extended hi-res graphics on the Apple." from Creative_Computing_v11_n02_1985_Feb and typed source again

Result is not what I expected. Maybe source has mistakes?

Hi, now that I have my Apple IIc, I am planning to start programming again and Double Hires was something I was always trying to learn.  Back in the 80's I figured out a lot about how they work and basically wrote my own routine to transfer disks between my Laser 128 and a PC using Copy II+ on the Apple side and a terminal program and QuickBasic on the PC.  I also wrote a program to display Double Hires graphics images on a PC.  However, doing anything besides images was difficult to nearly impossible until I purchased ZBasic.  ZBasic is a great alternative to Applesoft Basic.  I wrote the board game "Risk" using double hires graphics and a mouse.  Right now my Risk program is sitting on a lonely 3.5 inch disk that I can't read at the moment.  I do have a MAC LC III with Apple IIe card that can read 3.5 inch disks, but the serial port has too many pins compared to my IIc cable I use with ADTPro.  So reading that floppy is on hold until I either buy or make a cable or adapter.

 

Sorry for rambling, but in summary, if you learn ZBasic, then Double Hires becomes very easy to use.  The only weird thing is you have to program in 1024x768 resolution which is automatically converted to the 140x192 display by Zbasic.  When designing your graphics you have to do the math to know where your coordinates should be in the 1024x768 world.  The reason they did this is so your basic program could be easily ported to other platforms such as a PC. 

 

Aside from all of this, as a challenge, I am looking forward to reading through the above posts and learning how to better do DHR with Applesoft.

Your LC III should be able to read a Prodos disk directly.  All you need is the control panel called PC Exchange.

Thanks, but how do I get it to the PC?  On another floppy?  The LC III isn't networked or anything. I don't want to derail the thread, so you can PM me if you think that is better.

After the First Horizontal Line, it seems to Skip Every Other Column...  
 
It's Not so Noticeable on Real Hardware:

But when I ran the HGR1 program on AppleWin, you can see in the Upper Left Corner a Blue line segment, and then for every Horizontal line that is dropped, the Line Segment is just a Pixel...
