user: You are replying to All about "rendering!".

Write your reply.

assistant: I am having a little trouble with a piece of software I am writing.
In this application we must render a bunch of walls in an order to prevent
the polygons (walls, floors, roofs etc) from occluding.
So what I basically mean is that say your playing in doom, I must render the
walls so that they never occlude each other.
I've been doing this so far by using front->back (not back to front)
rendering method. This way I only need to plot "xmax*ymax" pixels and not as
many as when using the painters algorithm. This has worked fine so far, the
render knows to stop rendering when "xmax*ymax" (64000) pixels have been
plotted, however, there is now a slight problem. If anyone has ever played
doom2, picture yourself out in that large outdoors-room with a river in E1M1.
As you can see the renderer will never plot "xmax*ymax" pixels (when opposed
to inside) so this is where I've been stuck for the last 2 weeks. If anyone
has any code/idea/documentation on how to solve this problem then please
reply.

66030500000000 might possibly decode as ADD EAX,W[0] but you certainly

Once again getting into territory I'm none too sure about...
Consider this: A86 is a 16-bit assembler. If you try to assemble code
like    MOV EAX,12345678h
it will give you an error message because that's 32-bit source.
With the registered version of A86 you get also A386. If you try to
assemble that code with THAT assembler there will be no error.
My guess is that MASM (and TASM?) can be either 16- or 32-bit
assemblers and you tell them which to be by putting USE16 of USE32 at
the top of your source.
I don't use MASM/TASM so I can't be sure of this.
I thing A86\A386 is a better assembler - but that's a matter of
opinion so please, everybody, let's not get into that argument again.

Write your reply.

assistant: Hi Paul,
Correct, always. BTW, a nybble is four bits.
Often but certainly not always. On a PC this is (as far as I'm aware) correct
but there's no single definition of the size of a word, which tends to be
very
much hardware related. For this reason the next few are also a bit of a
problem.
Two words. Number of bytes depends on the size of a word.
Generally but not always. Again, there is no single definition.
Two dwords or four words.
Ten bytes. Normally used when dealing with the FPU.
I'll bet it's as clear as mud now. :-) To elaborate on the size of a word:
I've
heard of systems on which a word is 8, 24, 32, 64, etc. bits. e.g. On a
Commodore 8 bit machine a word is generally either 8 or 16 bits, depending on
which assembler or compiler you're using. I suspect that these things will
eventually get standardized but in the meantime you should always check your
assembler and compiler docs to see how many bits it uses for a word and/or
long. Some programs I've seen even allow you to alter the size of these
variables by using command line switches or compiler directives.

assistant: There are basically three levels of virtualization that DPMI implementations
can provide:
 No Virtualization
In general, stand-alone single tasking DPMI implementations will not
virtualize any hardware devices. These host extension programs  will execute
as standard DOS real mode drivers or programs. Extenders which use the
services provided by these DPMI host drivers will translate protected
mode DOS  calls to real mode  DOS calls. Normally  these extenders will
invoke DPMI services to return the processor to real mode (instead  of
virtual 8086 mode) when calling DOS.
Partial Virtualization
Some environments that execute under DOS will virtualize hardware devices,
provide virtual memory, or provide other services that require virtualization
of some hardware devices. Under these environments, DPMI applications will
always run at a non-privileged ring (usually ring 3). Some or all  hardware
interrupts will be virtualized, some or all I/O  will be virtualized, and
virtual memory may be supported. Under these implementations, page locking
services usually must be used to lock interrupt and exception handling code.
Complete Virtualization
These environments provide a completely simulated DOS environment. The native
operating system is something other than MS-DOS. Under these implementations
of DPMI, all devices will be virtualized to some extent. Normally, page
locking services will be ignored by these implementations since all physical
device interrupt and I/O handling will be performed by the operating system.
Programs will always run at a non-privileged ring.
That's because your operating system loads your application at protection
level which prevents it from using instructions such as lidt etc.
