Particle Trace

Particle Trace


Overview
Generates particle animation based on 2 component or 3 component vector data. The shape of the particle is a diamond shape (8 surfaces). The direction in which the particles are advected is determined by calculating stream lines in the neighborhood of the defined starting point. The particles are advected along the stream lines.


Parameters
Visible
switches on and off the display of particles.

Reset
resets all parameters.

Save MVG
saves data in an MVG file.

Help
displays help

Select Data
Selects the data to be distributed in the X, Y (Z) directions. Data components are in the X, Y and Z directions starting from the top in order. Further, the number of components should be at least two or three.

Calc All
The starting point at which particle advection begins is defined to be all the points.

downsize level
This is only valid when [Calculate at all points] is turned on and adjusts the precision of the data. When the value is 1, the data is with its original precision and the precision reduces as this value is increased (only for structured cell ).

display line
A line is displayed to indicate the starting point for particle advection.

rot
the line is rotated along the plane in which the data exists.

trans_x
The line is moved along the X direction in the data plane.

trans_y
The line is moved along the Y direction in the data plane.

line length
Sets the scale of the line length.

dim
Defines the number of cells on the line. The line is divided at these points, and each of these points become the starting points of the cells. Towards the center positions the line vertically in the center of the X axis

Operation buttons

- Reset resets the system to the initial state of time.

- Stop stops particle advection.

- Play plays back the advection once.

- Cycle plays back cyclically. When the end point is reached, the system goes back to the starting point and this is done repeatedly.

color
cells are colored based on the vector values.

glyph scale
sets the size of the glyph.

start time
Defines the start time at which particle advection begins along the stream lines.

end time
Defines the time at which particle advection ends.

step
Defines integral time (time step).

N-segments
Defines the number of time steps within a grid.

Max-segments
Defines the total number of time steps

order
sets the order of integration.

Display Trace
Drawing tailed line.
