3.13.7 FlowP

Method on mglGraph (C++): void FlowP (mglPoint p0, const mglData &x, const mglData &y, const mglData &ax, const mglData &ay, const char *sch="")

Method on mglGraph (Python): void FlowP (float x0, float y0, float z0, const mglData &x, const mglData &y, const mglData &ax, const mglData &ay, const char *sch="")

C function: void mgl_flowp_xy (HMGL gr, float x0, float y0, float z0, const HMDT x, const HMDT y, const HMDT ax, const HMDT ay, const char *sch)

The function draws flow thread for the plane vector field {ax, ay} parametrically depending on coordinates x, y from point p0 at level z = p0.z. The color of lines is proportional to \sqrtax^2+ay^2. Warm color corresponds to normal flow (like attractor). Cold one corresponds to inverse flow (like source). String sch sets the color scheme. Previous color scheme is used by default. The size of ax and ay must be equal. The minor dimensions of arrays x, y and ax must be equal too. Arrays x and y can be vectors (not matrices as ax). The vector field is plotted for each z slice of ax, ay. See also Pipe, VectC, Vect.

C function: void mgl_flowp_2d (HMGL gr, float x0, float y0, float z0, const HMDT ax, const HMDT ay, const char *sch)

The same as previous with x, y equidistantly distributed in interval [Min, Max].

Method on mglGraph (C++): void FlowP (mglPoint p0, const mglData &x, const mglData &y, const mglData &z, const mglData &ax, const mglData &ay, const mglData &az, const char *sch="")

Method on mglGraph (Python): void FlowP (float x0, float y0, float z0, const mglData &x, const mglData &y, const mglData &z, const mglData &ax, const mglData &ay, const mglData &az, const char *sch="")

C function: void mgl_flowp_xyz (HMGL gr, float x0, float y0, float z0, const HMDT x, const HMDT y, const HMDT z, const HMDT ax, const HMDT ay, const HMDT az, const char *sch)

This is 3D version of the first functions. Here arrays ax, ay, az must be 3-ranged tensors with equal sizes and the color of line is proportional to \sqrtax^2+ay^2+az^2. See section Flow 3D sample, for sample code and picture.
