DESCRIPTION

204       Each of the mlib_GraphicsDrawTriangleFanSet_*() functions draws  a  set
205       of  triangles  with  vertices at {(x1,y1), (x2,y2), (x3,y3)}, {(x1,y1),
206       (x3,y3), (x4,y4)}, ..., and {(x1,y1), (xn-1,yn-1), (xn,yn)}.
207
208
209       Each of the mlib_GraphicsDrawTriangleFanSet_X_*() functions draws a set
210       of triangles in Xor mode as follows:
211
212             data[x,y] ^= c ^ c2
213
214
215
216       Each of the mlib_GraphicsDrawTriangleFanSet_A_*() functions draws a set
217       of triangles with antialiasing.
218
219
220       Each of the mlib_GraphicsDrawTriangleFanSet_B_*() functions draws a set
221       of triangles with alpha blending as follows:
222
223             data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
224
225
226
227       Each of the mlib_GraphicsDrawTriangleFanSet_G_*() functions draws a set
228       of triangles with Gouraud shading.
229
230
231       Each of the mlib_GraphicsDrawTriangleFanSet_Z_*() functions draws a set
232       of triangles with Z buffering.
233
234
235       Each of the other functions draws a set of triangles with a combination
236       of two or more features like  antialiasing  (A),  alpha  blending  (B),
237       Gouraud shading (G), and Z buffering (Z).
238

PARAMETERS

240       Each of the functions takes some of the following arguments:
241
242       buffer     Pointer to the image into which the function is drawing.
243
244
245       zbuffer    Pointer to the image that holds the Z buffer.
246
247
248       x          Pointer to array of X coordinates of the points.
249
250
251       y          Pointer to array of Y coordinates of the points.
252
253
254       z          Pointer to array of Z coordinates of the points.
255
256
257       npoints    Number of points in the arrays.
258
259
260       c          Color  used in the drawing, or pointer to array of colors of
261                  the points in the case of Gouraud shading.
262
263
264       c2         Alternation color.
265
266
267       a          Alpha value for blending. 0 ≤ a ≤ 255.
268
269

RETURN VALUES

271       Each of the functions returns MLIB_SUCCESS if successful. Otherwise  it
272       returns MLIB_FAILURE.
