(About the author) |
| | | The most successful program of all time on Planet Source Code is RJSoft's textured 3D cube, it has had 176 excellent votes for it including my vote. People obviously were impressed by real time 3D texture mapping - it's the best graphics you can get. RJSoft's program produced these cool graphics using DirectX 7, it is a very well written program. But what if I were to tell you that it is possible to do this WITHOUT DIRECTX?! Yep, this is texture mapped 3D in PURE VB CODE! It doesn't use DirectX, no OpenGL, no DLL's, just label and image controls, and NO DRAWING API's - not even Windows ones. It doesn't use ANY API's in the main rendering loop!!! Yet it still has several rendering modes to choose from and runs at the following frame rates (on my 400Mhz PC).
Corners Only - 135 FPS
WireFrame - 120 FPS
Outline - 110 FPS
Flat Colour Polygons - 40 FPS
Single Texture Mapped Polygons - 20 FPS
Multiple Texture Mapped Polygons - 11 FPS
That's FAST! I don't promise the graphics to be as good as RJSoft's program, but I do promise they're done in pure VB code. You can spin the cube on the x,y and z axis and stop it too. You can change the rendering mode by pressing the spacebar. So, 176 of you voted for RJSoft's program using DirectX, I hope you think this deserves a vote too.
NOTE - for best performance run the compiled .exe (supplied) and close all other programs. This doubles the frame rates!

To RJSoft
I hope you didn't mind me
refering to your program, but I had to
since it was your program that made me
write my one - I thought I'd copy
whatever was the best program on PSC
and it was your's! Ofcourse, I like to
do things without DirectX so the
program changed dramatically, if you
look at the source code I'm sure you'll
see that I haven't copied a word of
your code. NEway, thanks 4 your prog,
it inspired mine!

This is pretty sweet. :) Usually, I
don't download Rotating Cube examples,
but I thought I'd check it out
anyway.
If you can find a more
constructive way to use this knowledge,
I'd be more inclined to vote for it...
Perhaps do what one other author did
and make a 3D Landscape Engine.
Just
thought I'd add my 2 cents worth. :)
Good job, hehe :)

No, I don't mind at all. I have looked
at your code and ran your program.
While the idea is ok, the results are
not as good as using DirectX. DirectX
was created to make graphics fast and
easier to use then direct code. Trying
to do this in pure VB is ok but not
very practical. You did a fine job on
this example so dont take this in bad
light. Your example shows you can work
with graphics without use 3rd party
dlls.

You're right, it's a bit dumb to make
3D stuff in VB. But if I ever get that
C++ and assembler stuff in my head it
might be a bit more useful...

Well done - I've been trying to work
out how to do this for years, and now
after looking at your code... I'm still
trying to workout how the texture
mapping thingy works. Excellant code
however it works
| 8/12/2000 8:02:31 AM:rino_2
Very good although it would be much
better using DX.
| 8/12/2000 11:18:26 AM:Marc Burgess
Wow, great, and stuff... Your coming up
with alot of decent stuff, but can't
use use that giant brain of yours to
come up with a full game, rather than a
spinny cube thing. From what i've seen,
you should be able to do more than
this, even if it means losing textures
or somthing.. And what happened to the
VBDoom game? If you put monsters on it,
I would like to see it. And anyway, I
don't see how you can call it VBDoom,
when it is nothing like Doom, and
everything like Wolvenstine. You don't
see me calling my tank game VB Unreal
Tornement do you?
| 8/12/2000 11:26:38 AM:Marc Burgess
Hey, don't get my wrong, I like all
your stuff, but you gotta admiit, a
game would be better than a spinny
cube. And keep up coding in VB, its the
best language in the WORLD!! Thats why
90% of planet source code in for VB!!
After all, last year, there was about
one 3D example on PSC, now there are
loads, with Texture maps, full games,
and DriectX - give it another 12
months, and people will be writing 3d
games in VB and selling them on the
open market. Every thing but VB s'ucks
ass!

Nice job! I'd vote but I hate demos
that nag me.
| 9/24/2000 5:26:01 AM:Richard Hayden
It runs VERY fast on my
950MHz.
Corners Only: 400 fps.
Wire
Frame: 351 fps.
Outline: 356
fps.
Flat Colour Filled Polygons: 170
fps.
Affine Single Texture Mapped
Polygons: 50 fps.
Affine Multiple
Texture Mapped Polygons:
32
fps.
That IS fast!
Well done on
another excellent project!

I don't know if this has happened to
other people, but I'm running windows
2000, and when I ran your example, I
got a nasty surprise. The entire cube
was tilted on its side, I'm not sure if
it's supposed to do that, or if it's
something to do with my computer's
configuration in general.
(I have a
500mhz computer, and I got only 32fps
with corners only, which was tilted as
well...)

To Erik Forbes (the second
feedbacker),
I hate to break it to
you, bro, but Simon IS the author of
the 3D Landscape Generator. Just
thought I'd point and laugh. No harm
meant.
| 9/24/2000 12:48:46 PM:The REAL SESoftware
§hit Simon... Are you ever going to
stop creating kick a§§ programs! WHO'S
THE MAN?!?!?!

I liked your code quite a bit. I was
toying with ways to do this for some
time now. However, in dissecting your
code, I came across 2 errors.
1)
After awhile, the code can lock up in
an infinite loop in the
AffineScanPolyEdge routine. It's caused
by the program looking for x = x2 or y
= y2 when it should be something like x
>= y2, since you are using variants
instead of bytes.
Which brings
up
2) you are using variants instead
of bytes in two of your most code
intensive routines. The statement
dim
x,y,z,i as byte
actually declares
x,y,z as variants and only i as a
byte.
After redeclaring your
variables, I went from 11fps to 17fps.

Looks great, but it can be a bitty
faster when you remove the 'setpixel'
statement. Looks the same, but draws
also negative.

Tutorial is great man, if you need an
artist, contact me (alas@EUnet.yu), I
wanna help for skeletonX, but I can't
reach your mail... <:-(
