DESCRIPTION

200       Each of the mlib_GraphicsFillTriangleFanSet_*() functions draws  a  set
201       of  filled  triangles  with  vertices  at  {(x1,y1), (x2,y2), (x3,y3)},
202       {(x1,y1), (x3,y3), (x4,y4)}, ..., and {(x1,y1), (xn-1,yn-1), (xn,yn)}.
203
204
205       Each of the mlib_GraphicsFillTriangleFanSet_X_*() functions draws a set
206       of filled triangles in Xor mode as follows:
207
208             data[x,y] ^= c ^ c2
209
210
211
212       Each of the mlib_GraphicsFillTriangleFanSet_A_*() functions draws a set
213       of filled triangles with antialiasing.
214
215
216       Each of the mlib_GraphicsFillTriangleFanSet_B_*() functions draws a set
217       of filled triangles with alpha blending as follows:
218
219             data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
220
221
222
223       Each of the mlib_GraphicsFillTriangleFanSet_G_*() functions draws a set
224       of filled triangles with Gouraud shading.
225
226
227       Each of the mlib_GraphicsFillTriangleFanSet_Z_*() functions draws a set
228       of filled triangles with Z buffering.
229
230
231       Each of the other functions draws a set of filled triangles with a com‐
232       bination of two or more features like antialiasing (A), alpha  blending
233       (B), Gouraud shading (G), and Z buffering (Z).
234

PARAMETERS

236       Each of the functions takes some of the following arguments:
237
238       buffer     Pointer to the image into which the function is drawing.
239
240
241       zbuffer    Pointer to the image that holds the Z buffer.
242
243
244       x          Pointer to array of X coordinates of the points.
245
246
247       y          Pointer to array of Y coordinates of the points.
248
249
250       z          Pointer to array of Z coordinates of the points.
251
252
253       npoints    Number of points in the arrays.
254
255
256       c          Color  used in the drawing, or pointer to array of colors of
257                  the points in the case of Gouraud shading.
258
259
260       c2         Alternation color.
261
262
263       a          Alpha value for blending. 0 ≤ a ≤ 255.
264
265

RETURN VALUES

267       Each of the functions returns MLIB_SUCCESS if successful. Otherwise  it
268       returns MLIB_FAILURE.
