fg_texmapz()Win32 DirectX Fastgraph/Light 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 zbuffered linear texturemapped 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 32bit 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 nonconvex polygon with fg_texmapz(), only a portion of the polygon will be filled.
