<@ToxicFrog>
Man. Compact edge-triggered anything in DF is harder than it sounds.
00:31
<@Vornicus>
Edge triggering needs a smidge of delay
00:33
<@ToxicFrog>
That's not really a problem.
00:33 * ToxicFrog studies the design for the SR latch some more
00:34
<@Vornicus>
Is it a crossing problem?
00:35
<@ToxicFrog>
No, it's a problem with implementing LE lines in a reasonable amount of space
00:35
<@Vornicus>
LE lines?

I need a latch that will respond to its S and R lines only when E is high

00:36
<@ToxicFrog>
This can trivially be done by adding two AND gates, but that triples the size of the latch

<@Vornicus>
A DFF is usually 5 NAND gates.
00:39
<@ToxicFrog>
Yeah. This is five times the size of an SR latch in DF.
00:39
<@ToxicFrog>
In DF, an SRL is a single gate.
00:39
<@ToxicFrog>
I'm aiming for no more than twice that.

<@Derakon[AFK]>
Is this Dwarf Fortress or something else?
01:02 Derakon[AFK] is now known as Derakon

<@Vornicus>
This is Dwarf Fortress.
01:03 * Vornicus goes down to the bottom layer of his fortress and builds a 6502. :P
01:03
<@Derakon>
Heh.
01:08
<@ToxicFrog>
I could implement my CPU gate for gate, but that would be huge and slow.
01:09
<@Vornicus>
heh
01:26 * Vornicus wonders what the DF world would pay for decision support services.

well, vorn, what would you charge to design a fortress that functioned as a turing device?

< AFKSkull>
how about a program to intercept direct3d draw instructions so as to insert additional 3d objects into the display of an application?
02:23
<@Vornicus-Latens>
More than you have.

< AFKSkull>
I figured as much
02:24
< AFKSkull>
though it never hurts to ask^_^
02:24
<@Vornicus-Latens>
More than most people have. Partly because step 1 is "get a decent windows machine" and step 2 is "learn direct3d"
02:25
< AFKSkull>
how about the exact same thing, but in openGL?
02:26
<@Vornicus-Latens>
Well, that gets rid of step 1, but step 2 is still in there, slightly changed
02:29
< AFKSkull>
right. s/vorn/mcmartin?

Though unless you're /in/ the program you're going to have fun trying to hack into that stream.

<@MyCatVerbs>
LD_PRELOAD hack to intercept GL calls.
08:26
<@MyCatVerbs>
Works well enough for things like making all triangles semitransparent. Inserting an object in doesn't sound so feasible, though - what if you need to work out the ingame coord system? Not actually doable in the general case.
