Axiom Requests

Mouse would be nice. I think there could be the option to use the Doors CS7 mouse or a standalone routine maybe. However keep in mind not everyone wants to buy an adapter to connect their mouse to the mini-USB port, so such program would require that arrow keys and two keypad buttons can alternatively be used if no mouse is connected.

I have one: Multiple Buffer Suppert. Meaning, you can have two, three, or four Graph screen buffers, with diff. symbols for each, and different DispGraphs draw different ones to the screen. Also, you could OR one buffer over the other when displaying. This would be soooo useful.

I'm thinking this removes greyscale, so,

Dispgraph = Buffer 1
Dispgraphr = buffer2
DispGraph(Degree symbol0 = Buffer Three
DispGraph' = Buffer 4

And so on, applied for all the drawing commands (including Line, preferably)

[Builderboy]

Where would the memory for the 4th buffer come from?

[willrandship]

I don't know RAM pages? There's tons of space there, right?

[Builderboy]

Yeah, but you have to swap into it, after which you lose the other 3 buffers

[willrandship]

But a Buffer takes 768 bytes. A Ram page has 8000, right? That's 10 buffers with a few bytes of breathing room, if I did my multiplication right

Also another request: Partial screen updates for more speed. As in, specify update a rect from 0,0 to 10,10, only changing 100 pixels, instead of the whole screen.

[Builderboy]

True, but where is your program?  It was in the *other* ram, the one you just swapped out of now you have 10 buffers and no code!

- grayscale package for cleanly displaying 3,4,5,6,7 and 8 level grayscale based on 2-3 buffers
- quick RLE compressor/decompressor (different from pucrunch due to a smaller size and faster speed)
- I'll second stereo sound
- OOP control axiom

[Builderboy]

How could you use OOP in an Axiom?

[Ashbad]

I'm sure there are ways I had a system pseudo coded out, but I gave it up because it would be a bit hard to make in assembly.  But, if no one else makes it, maybe I can later on

[willrandship]

@BuilderBoy That's why your routines fit in the other half of the RAM not taken by the four buffers, and return you like a subroutine when finished.

@AshBad with the newer dispgraph, 7 level is easy enough. swap between 0 and 1 (4 lvl) every frame for one between them. It doesn't look half bad, either! same for 1 and 2, 2 and 3. It looked hideous before 0.5.1, but now it's pretty decent.

[Builderboy]

Will, but what I mean is that as soon as you access the second page of Ram, every part of your program is gone, because its in a different Ram sector that you don't have access to anymore

[Ashbad]

Though, I think an assembly version would look better

To tell the truth, 5-7 level grayscale is extremely similar to 8 level

[willrandship]

So, how does one use it in a program? seems like there must be some way to switch back and forth....

@Ashbad, sure, but try it! 3 transitions to 5 the same way 8 is harder though.

[Builderboy]

Im no expert, but I believe you have to be executing from the OS, or from an App in order to control the swapping of RAM pages and still have it be useful.  But anybody feel free to correct me
