# Function: TimeOfImpact() > **TimeOfImpact**(`output`, `input`): `void` Compute the upper bound on time before two shapes penetrate. Time is represented as a fraction between [0,tMax]. This uses a swept separating axis and may miss some intermediate, non-tunneling collisions. If you change the time interval, you should call this function again. Note: use Distance to compute the contact point and normal at the time of impact. CCD via the local separating axis method. This seeks progression by computing the largest time at which separation is maintained. ## Parameters • **output**: [`TOIOutput`](/api/classes/TOIOutput) • **input**: [`TOIInput`](/api/classes/TOIInput) ## Returns `void`
