(make vertex pyramide clip) Checks labda and uses this to make decision about clipping the line segment from v1 to v2. labda is the factor by which the vector is cut. ( calculate s + l * ( t - s )). The result is appended to the vertex list of this face.

Parameters:
v1start coordinate s

b1
b2

Fill the z buffer. The face buffer is not operated on!

This is one of the z buffer fill functions called in zbufclip() and zbufwireclip().

Parameters:
v1[4 floats, world coordinates] first vertex
v2[4 floats, world coordinates] second vertex
v3[4 floats, world coordinates] third vertex

Fill the z buffer, but invert z order, and add the face index to the corresponing face buffer.

This is one of the z buffer fill functions called in zbufclip() and zbufwireclip().

Parameters:
v1[4 floats, world coordinates] first vertex
v2[4 floats, world coordinates] second vertex
v3[4 floats, world coordinates] third vertex
