Representación de superficies Z=f(x,y)

This is a module that enables representing functions z=f(x,y). This is very useful for creating different surfaces in a very simple way. The base used is a triangular grid instead of a square grid. To modify the shape of one of the surfaces provided, follow these steps (see Superficie z(x,y) onda circular atenuada): Step 1: On line 3, we can modify the values of different parameters such as alt, ext, n_ond or alt1. By modifying those parameters, we slightly change the shape of the surface. Step 2: On line 115, we can modify the parameter lad_triang. This value gives us the size of the triangles that form the triangular grid. The surface is smoothed by reducing this value but increases the rendering time. Good results are usually obtained for values of lad_triang ranging from 2 mm to 0.5 mm. Step 3: On the same line 115, we can modify the parameters x0, x1, y0 or y1. These values, in mm, determine the limits of the surface that we represent. For example, for values x0=-20, x1=30, y0=-30, y1=10, we would obtain a rectangular base 50mmx40mm. The rendering time is directly proportional to (x1-x0)*(y1-y0)/lad_triang^2. To represent our own function, follow these steps (see Superficie z(x,y) onda circular atenuada): Step 1: On line 3, the current function is replaced by another function. If additional parameters are added to the definition of a function, we multiply the ability to create new shapes. Step 2: On line 6, the name of the function cos_rev_atenuada_1 is replaced by the name of the new function defined on line 3. These surfaces are generated through juxtaposition of truncated triangular prisms (equilateral triangles). These surfaces can be used as auxiliary elements to create more complex forms.
