Each of the single-slab light field include two files:

A "parameters" file that contains the following in plain ASCII format

			samples_u samples_v samples_s samples_t

			uv_corner1_x uv_corner1_y uv_corner1_z uv_corner1_w  uv_corner1_p uv_corner1_q
			uv_corner2_x uv_corner2_y uv_corner2_z uv_corner2_w  uv_corner2_p uv_corner2_q
			uv_corner3_x uv_corner3_y uv_corner3_z uv_corner3_w  uv_corner3_p uv_corner3_q
			uv_corner4_x uv_corner4_y uv_corner4_z uv_corner4_w  uv_corner4_p uv_corner4_q

			st_corner1_x st_corner1_y st_corner1_z st_corner1_w  st_corner1_p st_corner1_q
			st_corner2_x st_corner2_y st_corner2_z st_corner2_w  st_corner2_p st_corner2_q
			st_corner3_x st_corner3_y st_corner3_z st_corner3_w  st_corner3_p st_corner3_q
			st_corner4_x st_corner4_y st_corner4_z st_corner4_w  st_corner4_p st_corner4_q

For example, the following parameters

			16 16  256 256

			-2 -2  2  1   0  0
			 2 -2  2  1   1  0
			 2  2  2  1   1  1
			-2  2  2  1   0  1

			-1 -1  0  1   0  0
			 1 -1  0  1   1  0
			 1  1  0  1   1  1
			-1  1  0  1   0  1

specify a light field with 16x16 samples in uv and 256x256 samples in st. The lower-left (0,0) corner on the uv plane is at (-2,-2,2,1), the lower-right (1,0) corner is at (2,-2,2,1), etc.

A "data" file of length samples_u * samples_v * samples_s * samples_t * 3 that contains the raw uvst data, given as RGB triples. This is raw binary data expressed as bytes in RGB order with no padding or line breaks. In C, you'd read it using something like
```
				FILE *lfdatafile = fopen("data", "rb");
				for (i = 0; i < uwidth*uheight*vwidth*vheight; i++) {
						unsigned char buf[3];
						fread(buf, 3, 1, lfdatafile);
						unsigned char red = buf[0];
						unsigned char green = buf[1];
						unsigned char blue = buf[2];
						/* Do something with the data... */
				}
		
```
The order of the samples varies fastest in "t", next fastest in "s", then "v" and "u". That is, looking at (u,v,s,t) indices, the first sample is (0,0,0,0), the next one is (0,0,0,1), and so on.
