DESCRIPTION

198       Each of the mlib_GraphicsDrawTriangleSet_*() functions draws a  set  of
199       triangles  with  vertices  at  {(x1,y1),  (x2,y2),  (x3,y3)}, {(x4,y4),
200       (x5,y5), (x6,y6)}, ..., and {(xn-2,yn-2), (xn-1,yn-1), (xn,yn)}.
201
202
203       Each of the mlib_GraphicsDrawTriangleSet_X_*() functions draws a set of
204       triangles in Xor mode as follows:
205
206             data[x,y] ^= c ^ c2
207
208
209
210       Each of the mlib_GraphicsDrawTriangleSet_A_*() functions draws a set of
211       triangles with antialiasing.
212
213
214       Each of the mlib_GraphicsDrawTriangleSet_B_*() functions draws a set of
215       triangles with alpha blending as follows:
216
217             data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
218
219
220
221       Each of the mlib_GraphicsDrawTriangleSet_G_*() functions draws a set of
222       triangles with Gouraud shading.
223
224
225       Each of the mlib_GraphicsDrawTriangleSet_Z_*() functions draws a set of
226       triangles with Z buffering.
227
228
229       Each of the other functions draws a set of triangles with a combination
230       of two or more features like  antialiasing  (A),  alpha  blending  (B),
231       Gouraud shading (G), and Z buffering (Z).
232

PARAMETERS

234       Each of the functions takes some of the following arguments:
235
236       buffer     Pointer to the image into which the function is drawing.
237
238
239       zbuffer    Pointer to the image that holds the Z buffer.
240
241
242       x          Pointer to array of X coordinates of the points.
243
244
245       y          Pointer to array of Y coordinates of the points.
246
247
248       z          Pointer to array of Z coordinates of the points.
249
250
251       npoints    Number  of  points in the arrays. npoints must be a multiple
252                  of 3.
253
254
255       c          Color used in the drawing, or pointer to array of colors  of
256                  the points in the case of Gouraud shading.
257
258
259       c2         Alternation color.
260
261
262       a          Alpha value for blending. 0 ≤ a ≤ 255.
263
264

RETURN VALUES

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