hi,
i need to create a basic object in opengl, e.g. a house. this could be done easily enough but all the vertex coordinates and facet windings have to be read in from another file. So far i have managed to open the file and read in the vertex coordinates. I don’t have a clue how to read in the facet windings.
in data file i'm reading from looks like this
1.0
-1.0
1.0
-1.0
-1.0
1.0
........
........
2 3 11 1 0
4 5 7 12 6
........
........
(the 1's and -1's are the vertex coords and the line of numbers are the facet windings)
the code for the input looks like this
GLfloat vertices[12][32];
GLint facets[8][5];
void entr(){
char filename[21];
FILE *in_file;
printf("\ntype name of file: ");
gets(filename);
in_file = fopen(filename, "r");
if(in_file==NULL)
{
printf("\ncannot open file: %s \n", filename);
return 1;
}
GLfloat num, row, col;
GLint row1, col1;
/*get data for vertices*/
for (row=0; row<12; row++)
{
for(col=0; col<3; col++)
{
fscanf(in_file, "%f", &vertices[row][col]);
}
/*get data for facets*/
for (row1=0; row1<8; row1++)
{
for(col1=0; col1<5; col1++)
{
fscanf(in_file, "%f", &facets[row][col]);
}
}
}
}
how do i get the second set of numbers to read in?
thanks
