Hallo.
I'm trying to convert my 2D matrix utility functions to use vala.
In C I have a struct containing a 2D static array rappresenting the matrix:
typedef struct _Matrix Matrix;
struct _Matrix
{
float mat[4][4];
}
Converting in vala, it becomes:
[Compact]
public class Matrix
{
public float mat[4,4];
}
But compiler doesn't support multi dimensional embedded array!!
If I write in the following way it embeds correctly the mono dimensional
array:
Compact]
public class Matrix
{
public float mat[16];
}
But it is not what I whant.
Eventually I can add inline getteres and setters:
[Compact]
public class Matrix
{
public float mat[16];
public inline float get(int row, int col)
{
return mat[row*4 + col];
}
public inline void set(int row, int col, float val)
{
mat[row*4 + col] = val;
}
}
But compiling with vala -C, I see that inline doesn't do nothing!!
Thik about matrix calculation in a 3D application:
if to read or update a value in a matrix I have to call functions,
calculations slow down to much!!
What can I do?
P.S. sorry for my bad english...
Michele
