The nature of the resistive transition for a current applied parallel to the magnetic field in high-{ital T}{sub {ital c}} materials is investigated by numerical simulation on the three-dimensional Josephson junction array model. Using finite-size scaling it is shown that {ital for} {ital samples} {ital with} {ital disorder} the temperature {ital T}{sub {ital p}} of the {ital c}-axis resistivity transition corresponds to a percolation phase transition of vortex lines perpendicularly to the applied field. The value of {ital T}{sub {ital p}} is higher than the temperature of the resistive transition for {ital j}{perpendicular}{ital H}, but decreases with the thickness of the sample and with anisotropy. We predict that critical behavior around {ital T}{sub {ital p}} should reflect in experimentally accessible quantities, as the {ital I}-{ital V} curves. {copyright} {ital 1996 The American Physical Society.}
