6 Dimensional Array

[-=Te[]v[]eR=-]

Hi All,
Well I also have similar problem, where data from objects properties is very time sensitive. I am trying to store a pixel with 5 more or attributes, and then form a new array based on the rules controlling any of the attributes.
Would you still recommend file database if I had excessive amount of RAM (solid state) and multiprocessor system ?

Could you please give an example how to fill up a 6 dimensional array with simple rules in VB? Much appreciate if you could, this is a hobby, although
I know that VB is not best for graphic programming, at the moment I am trying to understand the logic of how to be an efficient programmer and will learn other language later.

This is where I am at so far :


'Reading pixels from picture and displaying their color values
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click ' Has one Picturebox, one ListBox and one button
ListBox1.Items.Clear()
ListBox1.Items.Add("Pixel Color Factor")

Dim img As Bitmap = New Bitmap(PictureBox1.Image) 'Storing jpg
Dim c As Color 'Extracting color

'Dim myPolygon(,,,,) As Integer How does this work ?
Dim countPix As Integer = 0 'Pixel counter

Dim writer As System.IO.StreamWriter
writer = System.IO.File.CreateText("myRecs.Txt")
TextBox2.Text = "W: " + img.Width.ToString + " H :" + img.Height.ToString 'Displaying pictures size in pixels

Dim j As Integer = 0
Do While (j < img.Height) 'Reading rows from jpg

Dim i As Integer = 0
Do While (i < img.Width) 'Reading columns from jpg

Dim valPix As Integer = 0

c = img.GetPixel(i, j)


Dim a As Integer = Convert.ToInt16(c.A)
Dim r As Integer = Convert.ToInt16(c.R)
Dim g As Integer = Convert.ToInt16(c.G)
Dim b As Integer = Convert.ToInt16(c.B)

valPix = Convert.ToInt16(c.R) + Convert.ToInt16(c.G) + Convert.ToInt16(c.B) 'Calculating sum of colors. I think we can call that brightness
'listing raw data x,y,amount of red,green and blue
ListBox1.Items.Add((i.ToString + ("," _
+ (j.ToString + (" " _
+ (r.ToString + (" " _
+ (g.ToString + (" " + b.ToString) + (" " + valPix.ToString)))))))))

'writing formated data for later use
writer.WriteLine("Index :" + countPix.ToString + " X : " + i.ToString + " Y : " + j.ToString + " Red : " + r.ToString + " Green : " + g.ToString + " Blue : " + b.ToString)
writer.WriteLine(" ")
i = (i + 5) 'High resolution image requires serious processing power, skipping 5 columns and 5 rows
countPix = (countPix + 5)
Loop
j = (j + 5)
Loop
writer.Close()

End Sub


Thank your for your time.

It appears you're using VB.Net. I've asked the moderators to move your post to the proper forum.

It doesn't look to me like you want a 6 dimensional array, it looks like you want a class with 6 member variables. That would be a whole lot easier to work with, too.

6 dimensions? So that would be like a collection of collections of collections of collections of collections of collections all of one data type in a hyper-hyper-hypercube? I'm just off to a darkened room with a damp cloth.

I can't even wrap my head around the dimensions required. I'm still trying to get used to the fact that I see in 3 dimensions!

Actually its more like having multiple levels of nested indexes to a single item.
