Hey benny,
thanks for your reply and nice to see you here. okay, i understand about normal life.
Nice to hear, you are connected to Shockwave via facebook and according to his posts, he is hopefully fine.

seeing what happens to this forum and its great community (seems to be "death") makes me really sad.
i would like to know if there is a way to backup all this postings (forum), before it may be offline one day.

can you tell something, what happens to this forum and its great old community, that this place seems to be death?

However, i am really glad to hear from you and i hope you are still fine (even if normal life took over).
best regards

hmm.... has nobody any info?  ???

It made me really sad, to see this forum seems to be "death". What happens to Shockwave and how is doing the admin part of this site?
Btw, in the past i had nicks email- and private post adress. sadly i lost them. Is someone still in contact with him, or has any contact infos for me?
Thanks for PM.

Thanks for your reply to this really old topic and nice you liked the tutorial ;-)
Due fact of health and time problems, i cant do a tutorial for a dot tunnel atm and probaly for the next 12 month.
There are another two very old projects i would still like to continue from time to time.

I continue to fight and wish that someday there will be a few small steps forward in terms of my health.
Then I would like to create more tutorials.

Thanks for the PB v5.70 compatible modification

Amazing and very cool Demo Test you did there!
I really like the scene and the music! Cant wait for final version   :clap:

Hi guys.
As the topic says hopefully all. I was long time away and taked a look to the forum from time to time.
I am really suprised, because it seems to me, that this forum is nowadays very still / inavtive.
Where are the activities from the old days and where are all the famous and amazing guys/coders?

I noticed that even some of the well known guys from the older days hasnt been here for a while  ???
Have i missed something?

Very very nice and funny production!
I found the goal with the first try... -> nice idea of what happens next ;)

Thanks for your reply.
Calcuating the width and height of an area or an image isnt the problem ;)

If you know Photoshop for example, there is a "navigation window" for the artist to see the visible area of the image (if you are zoomed in). The visible area will be drawn in the "navigation window" with a red border/box.

If the image is zoomed (as like on the screenshot), i have problems how to calculature the area of the red box in the navigation window.

Here is my code to draw a  cube like color box. I am not sure, if there is another or better way to generate/draw this colored cube. Most graphic programs are using a more rotated colorCube ^^ If you are interested, how i found out the math to draw this cube, i downloaded an original colorCube as PNG from google. Then i extracted each color channel and saved this as own image. So i managed to see how are the gradients and how to start coding my colorCube step by step.

Code: [Select]
long bufferColor[256 * 256];

// Clear Background

for (int i = 0; i < 256 * 256; i++)
bufferColor[i] = RGB(64, 64, 64);

// Draw ColorCube (routine by va!n)

for (int y = 0; y < 128; y++)
for (int x = 0; x < 128; x++)
bufferColor[(64 + x - (y / 2) + (y * 256))] = RGB(x * 2, 255, y * 2);
bufferColor[x + (y / 2) + ((y + 128) * 256)] = RGB(x * 2, 256 - (y * 2), 255);
bufferColor[128 + 64 + (x / 2) - (y / 2) + (y + x) * 256] = RGB(255, 256 - (x * 2), y * 2);

ASM / Re: A 256-byte inspired by Fritz Lang's Metropolis
« on: September 23, 2015 »

Just wow! When i saw your prod the first time on pouet, i was really speachless!!
How the hell is that possible? Just unbelievable and extrem impressive to me!  8)

I saw some other of your truly amazing 256 byte entries  too. You are doing a really great and mindblowing job!
K++ for your great work and for sharing even the asm source codes! (sadly i dont understand much of the source, so i cant convert it to C or psydo basic to understand how this magic works ;)

Keep on your great work!
best regards

General chat / Emulators for smartphone OS?
« on: September 23, 2015 »
In about two weeks i teach a small group of senior citizens and giving an instruction course for smartphone OS (Windows Phone, Android, iOS). Are there any good WindowsPhone / Android / iOS emulators for Windows to show the OS via beamer on a big wall?

I have some trouble with some basic math and cant find any infos / math about it on the web.

I am loading and showing a bitmap inside a window and i can zoom it in/out (ImageWidth * ZoomFactor), where ZoomFactor range from int 1 to 32.
A smaller scaled version of the original bitmap will be shown as preview in a so called navigation window (like photoshop).

At this point i know following values/infos:

   - The client width and height of the window (where the image will be drawn)
   - Original image width and height
   - width and height of the scaled/zoomed image (imageWidth * zoomFactor)
   - width and height of the preview area (where the scaled down image will be drawn)
   - width and height of the  image preview (navigation window)
   - The zoomFactor ( 1 == 100% | 2 == 200 %... )

The bitmap preview should show a rect of the area, we are zoomed in / which is visible. (see screenshot from photoshop)
How to calculate the (red) rect of the visible area?

Something i tried (just as example):
ClientWidth = 1024 | ImageWidth = 1280 -----> (100/(ImageWidth*zoomFactor)) * ClientWidth == 80
Also 80 % of the original imageWidth ((1280/100)*80) are visible in this example.

Any idea where to find infos on the web or whats the name of this to search?

@Shockwave, do you still have the problem? If so, please PM me. I think, i have a working solution for your Win 7 / Win 8 genuine problem.

C / C++ /C# / How to fix black holes in drawing?
« on: July 03, 2015 »
While i studied carefully and in detail the RGB color channels of ColorCubes, i managed to generate each of the three CubeSide as a 256x256 RectImage. My next step was to draw each pixel transformed, so i get the effect of a ColorCube. However it seems there are two problems atm. My biggest problem is the right side face, where you will notice black holes inside the generated face.

Here is my code, drawing always a white pixel, so you can see the black holes...
Any idea whats wrong?

Code: [Select]
for (int y = 0; y < 127; y++)
for (int x = 0; x < 127; x++)
bufferColor[ 128+65+(x/2)-(y/2) + (y+x)*256] = RGB(255, 255, 255);

Attachement is a screenshot of my generated work...

Thanks for the reply.
hellfire is right, his example is exactly what i am looking for.


Thanks a lot for your very helpfull answer and great explation/example !!  :cheers:
I mangaed to get it work  :updance:
