Hi All;

I need to write a 3d visualisation program to display a room with some
objects in it.

I have DJGPP...etc, but I am only running win 3.x, I need to use
opengl. Iam waiting for my copy of win95.

My question is how do I go about filling the edge/vertex/surface
arrays of the room and objects, in the mean time.

I have an idea of what the room will look like, I just do not know how
to turn the objects in my head to the structures below :<

Can anyone help?

The structure of the edge/vertex/surface arrays would be

typedef struc
	{
 	double x;
	double y;
	double z;
	} point3d;

typedef struc
	{
	point3d world; /* world co-ords */
	point3d eye;	/* eye co-ords */
	point screen; /* screen co-ords */
	} vertex3d;

typedef struc
	{
	int mapindex; /* index to the surface */
	int noofvertices; /* # of vertices forming the surface */
	int depthindex; /* to find depth of surface */
	int color; /* color of surface */
	} surface;

typedef struc
	{
	vertex3d vertex[NO_OF_VERTICES]; 
	surface sinfo[NO_OF_SURFACE];
	int map{NO_OF_SURFACE_VERTICES];
	} object;

object room;
object table;
object light;
object bed;
