    hi all!

    im having trouble copying from 2d array to 3d array. im not sure this is correct. can anyone help me? i suspect the error is in the last line.

    Code:
    [SIZE=2][COLOR=#0000ff][SIZE=2][COLOR=#0000ff]void[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2] TwoDimToThree()
    { 
    [/SIZE][SIZE=2][COLOR=#0000ff][SIZE=2][COLOR=#0000ff]int[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2] i,j,k; 
    [/SIZE][SIZE=2][COLOR=#0000ff][SIZE=2][COLOR=#0000ff]int[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2] row=512,col=512,slice;
    [/SIZE][SIZE=2][COLOR=#008000][SIZE=2][COLOR=#008000]//int slice_no = sav_slice_no[300];
    [/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2][/SIZE][SIZE=2][COLOR=#0000ff][SIZE=2][COLOR=#0000ff]for[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2](slice=0;slice<slice_no;slice++)
    { 
    [/SIZE][SIZE=2][COLOR=#0000ff][SIZE=2][COLOR=#0000ff]for[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2](j=0;j<row;j++) 
    { 
    [/SIZE][SIZE=2][COLOR=#0000ff][SIZE=2][COLOR=#0000ff]for[/COLOR][/SIZE][/COLOR][/SIZE][SIZE=2](k=0;k<col;k++)
    { 
    Dim_image3D[slice][j][k]=image3D[slice][pixel]; 
    } 
    } 
    }
    }
    [/SIZE]
    thank you!

    your image2D you are copying should be function of loop variables.

    Impossible to answer, since we don't know what you're trying to achieve. Are you copying from the 2D array to a single "slice" of the 3D array, or are you copying it to multiple slices? Are you mapping 2D pixels to exactly the same pixel in the slice, i.e. does 2D[p][q] get stored in 3D[slice][p][q]?

    Is your 2D array really called "image3D"? Using misleading variable names is a great way to confuse yourself.
