Animation module¶
-
class
factodiagrams.vis.animation.
Draw
(fps=60, animation_duration=0.3, pause_duration=0.6)¶ Creates animation of the prime factorization of a number.
This class contains functions displaying the animation of the prime factorization, buttons and the corresponding text.
- Parameters
fps (int) – animation framerate.
animation_duration (float) – fps realization time.
pause_duration (float) – pause duration at animation end.
txt (str) – text to display.
points (list of Point object) – list of points
target_positions (list) – list of points positions.
status (str) – status of the animation (play or pause).
speed (int) – animation speed.
n (int) – number to decompose.
- Parma speed_txt
text display speed.
-
compute_current_position
(o, t, total_frames, current_frame)¶ Compute point position at the frame current_frame.
This function calculates the transition point to t from the point o. Used in the “frame” function to calculate each frame of transitions.
- Parameters
o (list) – coordinates of old point.
t (list) – coordinates of new point.
total_frames (int) – number of frames between two diagrams.
current_frame (int) – current frame number
- Returns
coordinates of the transition point for the current frame.
- Return type
list
-
decrease_speed
(e)¶ Creates the “Sp. -” button.
Creates a button that allows you to decrease the speed of the animation. When the speed is negative the animation goes back and display speed text.
-
display_next_iter
()¶ Display the following diagram.
Displays the following diagram depending on whether the animation is forward or reverse.
-
display_points
(points)¶ Display points.
Clear previous points and display new points.
- Parameters
points (list of Point objects) – list of coordinates for each point.
-
display_speed
()¶ Displays animation speed.
Displays the expression “Speed :” followed by the speed of the animation.
-
display_text
(n, factors)¶ Displays the text associated with the number n.
Displays the number to be decomposed and its prime factorization in parentheses.
- Parameters
n (int) – number to decompose.
factors (array) – list of prime factors of n.
-
frame
(n, reverse=False)¶ Computes positions and display each points at each frame.
This function calculates intermediate points between each diagram for transitions.
- Parameters
n (int) – number to decompose.
-
generate_color
(i, n)¶ Creates RGB code that covers the entire color spectrum.
- Parameters
i (float) – x coordinate of a point.
n (int) – number to decompose.
- Returns
3 numbers for colors
- Return type
float, float, float
-
increase_speed
(e)¶ Creates the “Sp. +” button.
Creates a button that allows you to increase the speed of the animation and display speed text.
-
on_close
(e)¶ Close animation.
-
play_pause
(e)¶ Creates the “play/pause” button.
It’s a button that displays “pause” when the animation is running and “play” when paused.
-
class
factodiagrams.vis.points.
Point
(x, y)¶ Definition of a geometric point (x, y).
-
factodiagrams.vis.points.
generatePoints
(factors)¶ Returns the position of each point according to the number to decompose.
- Parameters
factors – list containing the prime factorization of a number.
- Returns
list of coordinates for each point
- Return type
list of Point object
