Abstract: First, enough points are arranged evenly in the element in the local coordinate system, according to the number of pixels within the element in the screen coordinate system. Second, the coordinates and the stress values of corresponding points in the global coordinate system are calculated by interpolation using the known node values. Finally, the color values of corresponding pixels in the screen are gotten from the pre-designed function relation between color and stress.
