We propose a curved triangular patch that is suitable for the field calculation by the integral equation methods. The interior control point of this patch is variably represented in the area coordinate as a weighted average of six control points.We can connect the patch to the three surrounding patches with G1 continuity on the sides. The whole surfaces to be treated can be represented as a collection of smoothly connected patches. This patch is applied to the surface charge method with the pseudo-particle fast multipole method. We demonstrate some electrostatic field calculations using several hundreds of thousands of proposed patches.
