Set particle radius range @param minRadius smallest particle radius @param maxRadius largest particle radius

Queue a runnable to be run on the GL rendering thread. This can be used to communicate with the Renderer on the rendering thread. Must not be called b

Set new particle coordinates somewhere off screen and apply new direction towards the screen @param position the particle position to apply new value

Resets and makes new random frame. This is useful for re-generating new fancy static backgrounds when not using animations.

Resets and makes new random frame where all particles are out of screen bounds and will be moving into the screen once animation starts.

Use this if you want to manually set to next frame, while animations are stopped.

Returns the number of particles in the scene @return the number of particles in the scene

Calculates the distance between two points @return distance between two points

Returns the maximum distance when the connection line is still drawn between particles @return maximum distance for connection lines

Returns smallest particle radius @return smallest particle radius

Returns angle in degrees between two points @param ax x of the point 1 @param ay y of the point 1 @param bx x of the point 2 @param by y of the point

Set new point coordinates somewhere on screen and apply new direction @param position the point position to apply new values to

Returns the connection like thickness @return the connection line thickness

Largest particle radius @return largest particle radius

Returns the connection line color @return the connection line color

Returns the particle color @return the particle color

Returns the speed factor. @return the speed factor

Used for checking if the particle is off-screen and farther than line length and it's radius. @param x the particle x @param y the particle y @return

Returns a delay per frame in milliseconds. @return delay between frames

Set number of particles to draw per scene. @param density the number of particles to draw per scene @throws IllegalArgumentException if density is ne

Set a delay per frame in milliseconds. @param delay delay between frames @throws IllegalArgumentException if delay is a negative number

Set the line color. Note that the color alpha is ignored and will be calculated depending on distance between particles. @param lineColor line color

Set the maximum distance when the connection line is still drawn between particles. @param lineLength maximum distance for connection lines

Set a line thickness @param lineThickness line thickness

Set the particle color @param color particle color to use

Sets speed factor. Use this to control speed. @param speedFactor speed factor

Creates an {@link EGLConfigChooser} for given multisampling value. Will fallback to lower multisampling mode or no multisampling mode at all if unsupp

Sets the background color for this View. Default is windowBackground. <p> Will not affect textures set in {@link #setBackground(Drawable)}. @param co

Initialize EGL for a given configuration spec.

Explicilty stop animating. This will stop animating and no animations will start automatically until you call {@link #start()}.

Generates new individual particle radius based on min and max radius setting. @return new particle radius
