Very Impressive!

Nice maths & imaging 5/5 I get about
10 fps for exe on my 400MHz m/c.
|
3/1/2002 10:52:07 AM:KaoS
Pretty cool code!
I get 15fps on
900MHz PIII.
I like it...more stuff
like that!

poor performance for a 900 Mhz!!! i get
21fps on my 672Mhz AMD Duron... and
28fps with all tricky switches on...
still have to see if i can optimize the
code.
Good Work!
|
3/1/2002 12:57:35 PM:Feuchtersoft
Neato. I don't get a single frame per
second, although it's cool, nonetheless.
|
3/1/2002 1:34:48 PM:Almar Joling
Feuchtersoft: Did you compile it? If
not, you really should. running the
program from VB is _very_
slow
<P>
I'm aware that there is a
difference between Intel/AMD machines.
I'm not sure what causes it, but I
guess it depends on some optimizations
VB adds.
<P>
If manage to optimize
the code more (besides moving the math
inline), I'd like to hear it
=-)

LOL, i get 3fps on my Athlon 1.2ghz!
|
3/1/2002 2:44:09 PM:Almar Joling
Did you compile it???? If not, then...
well something is really taking up
clock cycles on your PC.

I get 42fps on my AthlonXP and Radeon
DDR VIVO video card.

I'm getting 46fps now

Cool code. I get around 29 FPS on a 1.4

any...) Keep up the good
work!

Nice little example with a repectable
36fps on my machine. You can possibly
speed up the maths a little by creating
a look up table for the trig functions
rather than calculating them each time.
It would also be nice if you could move
the light position without pausing the
animation. Anyway 4 globes from me
you'll get 5 when you provide support
for other simple primitives e.g. cubes,
pyramids.

3/2/2002 1:08:21 AM:Feuchtersoft
Ah, I just compiled it. 33 fps. Ha! I
should probably read instructions next
time.

3/2/2002 12:55:59 PM:Hans J. Reich
You get a five - very nice, and I like
to see graphics stuff as a break from
all the winamp players and such.

Simply great!
Good work.

25 fps on Duron 850mhz running Win NT
Server 4 and Direct X 6. Not bad
performance considering these factors.

3/2/2002 2:20:11 PM:M. Highlander
i got 0 fps
oh wait you have to run it
first

COOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL!

I got 3fps in the IDE, but 23fps
compiled, on my 900mhz Athlon. Very
nice. Could you send me, or post a text
on how to convert xyz to xy
coordinates, and lighting and
viewpoint, and such. I will try to
figure it out from your code, but it
would be easier if there was a little
tutorial on the math that I could
read.
Very Nice!
|
3/2/2002 10:45:15 PM:Jamie Lindgren
Really cool. In the IDE I got a mind
boggling 3 FPS >< but when compiled I
got 29 (on my 1.5 gigz comp)
|
3/4/2002 10:53:02 PM:gonchuki
someone said would try on a pentium
133... i tested it on my AMD K5-100
result: 4 FPS
very good... i get the
same in IDE on my main pc...
|
3/5/2002 1:06:36 AM:havok
Nice program, u need votes. So u got a
5 from me.
Good job Almar, your
coding seems to amaze me, doing stuff
that other people don't even think
of.

I get an error relating to an undefined
function/sub: Could someone email me
and tell me why I can't seem to find
the
sub/funct:
"GenerateRayDirectionTable"
I have the DirectX 8 reference
listed without error? Ideas?
|
3/8/2002 2:40:50 AM:Almar Joling
I first used the math functions
contained in DirectX, but they were
slower than a simple VB version of
them... I forgot to remove the
reference. About your problem, the sub
is really there! I'm always running
with Full compile, never seen the error
before. I guess it would't compile
without it either, =-). The sub is in
mdlMain, almost on the top I
believe...

very nice 8 fps on my PII 350MHz
but
it takes 100% cpu usage.
|
3/16/2002 6:47:19 AM:Almar Joling
Yeah, it uses a simple do...loop, with
just one DoEvents. It doesn't give
Windows much time to breathe =-).
raytracers are known for their required
power, that's why we still do not see
any large real-time raytraced
animations yet.
|
3/25/2002 11:26:20 PM:Kevin m F
cool, but you need a fast comp to run it
|
3/26/2002 6:52:27 AM:Almar Joling
Yeah...realtime rendered scenes won't
exist for the next years anyway. It
requires so much calculations. That's
why raytracing a simple (3D) scene on a
post-stamp format can still take 5min
on a 500Mhz..
|
3/26/2002 4:58:58 PM:Almar Joling
I do like to know why Tim Sørensen has
give me a vote of 1. Didn't it work?
You're the only one that has voted so
low, so please I'd like to hear why so
I can modify the code as needed

hey very nice! i get about 10 fps on my
p2 400 mhz. you get five stars from me

a Really nice one, 2 fps IDE, 4 fps
Compiled, in my Pentium 200Mhz, 5
Globes from me!

I got 15fps on my 500mhz. I added ALL
the compiler optimizations and got that
up to 19fps. I then got rid of
SetDibits and used direct memory
writes. That improved the speed to
22fps. Finally I replaced the GetFPS
function with a simple timer control.
That brought the speed to
24fps.
Total improvement...60%.
|
4/17/2002 11:43:03 PM:Adriano Paladini
47fps on my AMD K6-III 450mhz with
GEFORCE 2 MX-400 (32MB).
|
4/18/2002 1:40:09 AM:Almar Joling
Bill: I would love to see that code :).
Although I think the timer control's
precision (which is bad!) is increasing
the FPS. Although the timr control does
run in it's own thread..hmm
|
4/18/2002 8:05:36 AM:Ozan Yasin Dogan
Intel PIII-450mhz Leadtek Geforce2Mx
Running at 210Mhz, 11 fps
Nice code
but still slow..
Graphics --> C++
|
4/18/2002 12:50:47 PM:Bill Soo
The timer control has poor resolution
(~55ms) but that doesn't matter much
since you are sampling a fairly large
time interval (1000 ms). The big time
savings is due to the fact that the
timer control only fires every second,
thus it only has to update the caption
once per second, instead of 22 times
per second.
|
4/19/2002 4:38:39 PM:Bill Soo
I replaced the frmMain.picRay.Refresh
statement with the InvalidateRect API
call to which I passed a small rect
structure that was just the part of the
picturebox containing the spheres. This
forced a repaint of only a section of
the picturebox, rather than the whole
thing, resulting in a frame rate of
33fps.
|
4/19/2002 5:40:20 PM:Bill Soo
The rotate and shadesphere functions
are pretty fast. Where the time seems
to be consumed is in the TraceScene
function (which calls shadesphere true,
but shadesphere is a small fraction of
the total time). So I took a look at
this code and made some small
optimizations that gained a fps. Then I
got rid of the MySphere and
ClosestSphere variables and referred
directly to Spheres. This gave me a
huge increase from 33 fps to
49fps!
So total optimizations went
from 15fps (original code) to 49fps....
|
4/20/2002 2:49:52 AM:Almar Joling
I believe it's faster than the original
C++ version then =oD. Good work!!

4/20/2002 2:50:51 AM:Almar Joling
btw, if you email me the updated
version, I'll update this submission.

My Pentium I 166mghz got a suprising 11
FPS - I honestly expected to get a lot
less, well done.

Why do all of you got so few fps? I got
about 220fps. -> Athlon 1800+
|
10/7/2002 11:56:49 AM:
Very impressive code. Ran icredibly
fast here at 150-250 fps on a Athlon XP
1700+, 512 Mb ddr mem and a Radeon 8500
|
10/7/2002 12:45:54 PM:Christopher Rouse
It worked V slow in the VB IDE I got
about 8-12fps, but when it was compiled
it was to fast about 200fps on my
Athlon XP 2000+ and 512mb of ddr mem
and a geforce 3 ti 200.

10/7/2002 3:59:12 PM:Almar Joling
I'm wondering why there is suddenly so
much interest for this code :P. A link
somewhere?

10/7/2002 6:43:38 PM:john sheridan
I think your code won code of the day,
so its in all the mailing list emails
that go out everyday. But thats wierd
cuz this is like a year old...
btw,
this code is amazing - i got 15 fps in
the IDE and 135 FPS! when its compiled
5 globes from me
|
11/24/2002 10:07:06 AM:Peter Wilson
Hmmm? If this is really ray-tracing (of
which I have seen no real evidence thus
far), then let's see some reflections!
|
11/24/2002 10:09:54 AM:Almar Joling
Peter Wilson: There is another version
of my raytracer which has shadows,
reflections and stuff..
|
3/17/2003 1:18:38 AM:
Impressive work, I'm averaging 230fps
on my AXP 1800
