2D Transformations - Rotation about
arbitrary point

2D Transformations -
Rotating a point from position (o.x, o.y) to position (oR.x, oR.y) <br> through an angle "theta" about pivot point (oP.x, oP.y)

oR.x = oP.x + (o.x - oP.x) * cos(theta) - (o.y - oP.y) * sin(theta)

oR.y = oP.y + (o.x - oP.x) * sin(theta) + (o.y - oP.y) * cos(theta) `

Usage:
Left click to position the object
Right click to position the pivot point

Polar to Cartesian Demo

Program to generate cartesian coordinates from polar coordinates

Usage:
Left and Right mouse button click and drag to rotate the line.

Middle mouse button click and drag to transform the origin of the coordinate system

Processing Lesson 1

This sketch demonstrates basics of programming in processing.

Topics covered include:
1. User defined variables (circleX, circleY)
2. Processing variables (width, height)
3. Processing functions (draw, setup, size, background, ellipse, fill, stroke)

Processing Coordinate System Demo

Simple processing program to draw a circles where the mouse was clicked on the screen.

This program also creates coordinate axes and text using font.

Usage:
Click left mouse button to create circle.
Click right mouse button to clear screen.

Random Sine and Cosine

A program to draw sin and cosine waves at various wavelengths, amplitudes..

User interaction is by clicking mouse buttons.

Draw Flowers

A simple sketch to interactively draw very simple flower style patterns.

Usage:
Left mouse click to place flowers.
Middle mouse click to erase.

Wiggly Flower

What does this Processing sketch do?
This sketch creates a flower like pattern around the mouse cursor position using sin and cosine math functions. At startup, its created at the center of the screen.

By adding randomization, we add wiggly effect to our creation and also a multi-colored output that changes over time.

USAGE:
Click left mouse button and drag for the flower to move along with mouse
