Firstly, we might notice that f is (1,x,x) and b is (0,x,x); r is (x,1,x) and l is (x,0,x); u is (x,x,1) and d is (x,x,0). So, the vertice frd has the coordinates (1,1,0), it’s the point P4.
The vertices:
v | f0(v) |
---|---|
O=bld | P2=frd |
P1=fld | P3=brd |
P2=frd | O=bld |
P3=brd | P1=fld |
P4=blu | P6=fru |
P5=flu | P7=bru |
P6=fru | P4=blu |
P7=bru | P5=flu |
