DESCRIPTION
Each of the mlib_GraphicsFillTriangleSet_*() functions draws a set of
filled triangles with vertices at {(x1,y1), (x2,y2), (x3,y3)},
{(x4,y4), (x5,y5), (x6,y6)}, ..., and {(xn-2,yn-2), (xn-1,yn-1),
(xn,yn)}.
Each of the mlib_GraphicsFillTriangleSet_X_*() functions draws a set of
filled triangles in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsFillTriangleSet_A_*() functions draws a set of
filled triangles with antialiasing.
Each of the mlib_GraphicsFillTriangleSet_B_*() functions draws a set of
filled triangles with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
Each of the mlib_GraphicsFillTriangleSet_G_*() functions draws a set of
filled triangles with Gouraud shading.
Each of the mlib_GraphicsFillTriangleSet_Z_*() functions draws a set of
filled triangles with Z buffering.
Each of the other functions draws a set of filled triangles with a com‐
bination of two or more features like antialiasing (A), alpha blending
(B), Gouraud shading (G), and Z buffering (Z).
PARAMETERS
Each of the functions takes some of the following arguments:
buffer Pointer to the image into which the function is drawing.
zbuffer Pointer to the image that holds the Z buffer.
x Pointer to array of X coordinates of the points.
y Pointer to array of Y coordinates of the points.
z Pointer to array of Z coordinates of the points.
npoints Number of points in the arrays. npoints must be a multiple
of 3.
c Color used in the drawing, or pointer to array of colors of
the points in the case of Gouraud shading.
c2 Alternation color.
a Alpha value for blending. 0 ≤ a ≤ 255.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
returns MLIB_FAILURE.
