1. , a kind of method that is impact point measurement space surface of revolution with little triangle core coordinate is characterized in that described method comprises the steps:

  • 1) determine the measurement range of space surface of revolution, the span of the polar radius R of the subpoint of point on coordinate plane on the surface of revolution of promptly described space, and in described scope, choose a plurality of polar radius R;

    2) at each polar radius R, make up a plurality of little triangles and calculate the normal vector on its determined plane, with its barycentric coordinates is impact point, utilization equal indicative method is measured a curve on the surface of revolution of space, described little triangle is projected as an equilateral triangle on coordinate plane, and the polar radius of one of them summit or the subpoint of this leg-of-mutton center of gravity on coordinate plane is R.
