The Workshop / Re: this would be nice to develop to 3d floormapping
« on: Today at 04:24:04 AM »
it's very nice - i like the rotation stuff   :t
but, i only seem to be seeing part of the image
this is about as much as i can see by adjustment



i am running XP if that makes a difference

GoAsm / Re: midi sound in GoAsm program
« on: Today at 03:46:24 AM »
i am with Japheth
simplify your code
no need for all those pointers to pointers   :P

you include winmm.inc, you may also need to includelib winmm.lib
(not sure how GoAsm works, in that respect)

hiya Jack
as you know, i am not much of a GoAsm guy   :P
but, this seems to work ok using MASM Syntax

GoAsm / Re: midi sound in GoAsm program

also - be sure to check your midi device volume
i don't know how many times i have found it set to 0   :P

The Campus / Re: Convert decimal to base 5?
« on: May 19, 2013, 11:13:37 PM »
Base5b is a bit faster   :P
it uses multiply-to-divide instead of DIV
and - it divides by 25, then gets 2 digits from a look-up table

Code: [Select]
Base5a

32244002423140

Base5b
443
32244002423140
34 25 28 33 20 27 43 32 24 40 clock cycles
EDIT: oops - fixed a slight bug in the buffer offset

i installed it - wanted it, anyways
eventually, i would like to be able to code this without it, though   :P
nothing wrong with setting goals - lol

i don't know what you mean by turning it off and on
the linear interpolation i am refering to is in the original image   :P

that is cool
you CAN see the linear interpolation   :biggrin:

thanks - i am familiar with ultrano - let me see what i can find   :t

by the way....
the images use 36 "actual" vertical data points
my code interpolates values in between to come up with 771 pixel high images
(35 x 22 + 1 = 771), i interpolate 21 points between each data point
for now, i am using linear interpolation
later, i may use some sort of best-fit curve function to get nicer results
i am guessing you will be able to notice the linear interpolation in the 3-d transform   :P

btw: i can wrap my head around 3-d transformation, easily enough
the part i don't understand is "this part is visible, this part isn't" - lol

The Laboratory / Re: A memory bug
« on: May 18, 2013, 11:26:04 PM »
there are times when the amount of stack space required is not known until runtime
i don't see any harm in probing the stack to increase the space available by TIB.StackLimit

Quote
In 32 bit PE executables that stack is set by the linker and
is part of the OS design, it is not a dynamic resizable stack.

i would say it's dynamic, as the OS continually balances the need for stack space with the need for heap space
