still working on my view-frustum culling implementation in jit.gen.

I have calculated the 8 points defining the part of space that I want to “compute”

How can I setup my 6 planes now ?

It means, how to translate the following code into my codebox/GenExpr stuff ?

// compute the six planes

	// the function set3Points assumes that the points

	// are given in counter clockwise order

	pl[TOP].set3Points(ntr,ntl,ftl);

	pl[BOTTOM].set3Points(nbl,nbr,fbr);

	pl[LEFT].set3Points(ntl,nbl,fbl);

	pl[RIGHT].set3Points(nbr,ntr,fbr);

	pl[NEARP].set3Points(ntl,ntr,nbr);

	pl[FARP].set3Points(ftr,ftl,fbl);

any help in that warm weekend would be very appreciate =)
