The <code>triangle</code> primitive is available in order to make more
complex objects than the built-in shapes will permit. Triangles are usually
not created by hand but are converted from other files or generated by
utilities. A triangle is defined by
<pre>
TRIANGLE:
triangle {
<Corner_1>, <Corner_2>, <Corner_3>
[OBJECT_MODIFIER...]
}
</pre>

where <code><Corner_n></code> is a vector defining the x,
y, z coordinates of each corner of the triangle.

Because triangles are perfectly flat surfaces it would require extremely
large numbers of very small triangles to approximate a smooth, curved
surface. However much of our perception of smooth surfaces is dependent upon
the way light and shading is done. By artificially modifying the surface
normals we can simulate a smooth surface and hide the sharp-edged seams
between individual triangles.
