Looking at Raypacket.cc we see:

void RayPacket::actualComputeHitPositions()
{
<snip>
       for(int i = rayBegin; i < rayEnd; i++){
               for(int j=0;j<3;j++)
data->hitPosition[j][i] = data->origin[j][i] + data->direction[j][i] * data->minT[i];
       }
<snip>
}

So, minT is what goes in the ray equation.

Hi,

Is the minT the "t" value of the ray equation that will give us the
hit position if we substitute it into the equation? Is it a proxy for
the "depth" or "z" value in traditional rendering?
