fg_texmapz()
Prototype void fg_texmapz (int *vertex_array, void *uv_array, double *xyz_array, int n); Sub fg_texmapz (vertex_array() As Long, uv_array() As Any, xyz_array() As Double, ByVal n As Long) procedure fg_texmapz (var vertex_array : integer; var uv_array; var xyz_array : double; n : integer); Description The fg_texmapz() function draws a projected z-buffered linear texture-mapped convex polygon in screen space, with 2D clipping. This function is called internally by Fastgraph's 3D functions and is not usually called directly by applications. Parameters vertex_array is the name of the array containing the (x,y) coordinate pairs of each polygon vertex. The first array element is the x component of the first vertex, the second element is the y component of the first vertex, the third element is the x component of the second vertex, and so forth. uv_array is the name of the array containing the (u,v) texture map coordinates for each (x,y) coordinate pair in vertex_array. The first two uv_array elements represent the (x,y) values at the first vertex in vertex_array, the next two uv_array elements are for the second vertex, and so forth. The fg_tmunits() function defines if uv_array contains integer or 32-bit floating point values. xyz_array is the name of the array containing the 3D (x,y,z) coordinates for each (x,y) coordinate pair in vertex_array. The first three xyz_array elements represent the (x,y,z) values at the first vertex in vertex_array, the next three xyz_array elements are for the second vertex, and so forth. Only the z coordinates are meaningful in this function. n is the number of vertices in each of the above arrays. Return value none Restrictions If you attempt to fill a non-convex polygon with fg_texmapz(), only a portion of the polygon will be filled.
