BezierDraw 1.1.4
An application designed to help you produce geometrical designs for Christmas cards or other stuff. more>>
The emphasis of the BezierDraw project was on being able to manipulate the objects with a mouse, clone the objects easily, and produce radial symmetry about a centre point.
The original intent was to produce a monochrome wireframe display which could be printed at high resolution, and perhaps colored by hand after printing.
The word Bezier is used in the program title because almost all the drawing is done using Bezier curves, the only exception being the occasional ellipse. The Bezier curves are spliced together in various ways to produce the desired object.
These curves were chosen for two reasons: firstly, they are rendered extremely rapidly by the graphics engine, so it is possible to do live manipulation with a mouse; secondly, the standard vector graphics file formats such as SVG have full support for them.
Since Bezier curves were used, the resulting shapes are not absolutely true hyperbolas or trochoids; however, in most cases you would be hard-pressed to tell the difference.
The program is written in Visual Basic 6, and has no special installation procedures.
Main features:
- Library of objects expanded to include some of the more complex closed-form shapes like cardioids and trochoids.
- Support for a coloring operation which operates like a floodfill in a bitmap, with a color-picker.
- Support for a zoom feature, for more precise positioning of objects.
- Support for SVG output, to make it more web-compatible.
- The corollary to SVG output is that color-filling can be done using other programs, such as Inkscape, which use a completely different set of rules for filling objects: totally vector-based, not bitmap-based.
System requirements:
- You must set the color depth of your monitor to be 24-bit or higher, sometimes called True Color
3D Curves 6.1
3D Curves draws curves of the form y = F ( x , z ) in 3-D. more>> Draws curves of the form y = F ( x , z ) in 3-D. y is "up" the screen, x is across the screen, and z appears to go "into" the screen.
Functions must be entered in ALL UPPER CASE or ALL LOWER CASE. Example z*sin(x) + (1-z)*tan(1/x).
You need to play around with the scale (typically in the range 0.1 to 10) and the ranges until you like the picture.<<less
SmartCurve 2.1
SmartCurve allows you to modify the curves in an image. more>> Photoshop Elements offers in opposite to its professional version no curves command. Thats a pity, because curves are a valuable tool for image editing.
To remedy this shortcoming this site offers the plugin SmartCurve to upgrade this ability. Of course this plugin can be used from all programs which can integrate Photoshop plugins.
Features:
* Curves adjustment of RGB and gray images.
* Full support of 8 and 16 bits color depth.
* Use of the more common gamma correction.
* Smart-display of the live histogram.
* Auto level correction by setting of shadows and highlights.
* Remove of color casts by setting of multiple midtones.
* Highlighting of clipped colors.
* Different color spaces like RGB, CMK, Lab and others.
* Channel masks to limit curve effects.
* Works as smart filter in PhotoShop CS3.
* Pixel and percentage curve editing and view.
* Batch Mode for applying a curve on multiple images.<<less
CableGuys Curve 0.5 Beta
A synthesizer for your VST sequencer that allows you to draw your own waves more>> A synthesizer for your VST sequencer that allows you to draw your own waves
Cableguys Curve plugin was designed to be a synthesizer for your VST sequencer that allows you to draw your own waves.
It has 3 oscillators (each of them can be set to either one of four user-waves or to sine, saw, pulse, triangle or noise) as well as two synced and two unsynced LFOs. You can set an LFO to 0.1 Hz or you can set it to several kHz. You can even set the LFO frequency to the frequency of the note you are currently playing.
Main features:
- Has drawable modulation matrixes. Use an LFO to modulate the pitch and you get FM, use an AHDSR-Envelope to modulate the filter cutoff and you get a nice filter envelope.
- You can play up to 128 notes at one time.
- All parameters can be automated (except for the user-waves and modulation matrixes) in your sequencer (Ableton Live, Steinberg Cubase).
- Curve can be told to render bandlimited, aliasing-free sounds. But you can also turn on aliasing to produce vintage digital sounds.
- Shows spectrographs of the waves you draw.
- Lets you set snapshots of your waves for faster editing.
Known Issues
- The Beta works only with 44.1 kHz.
- Only tested with Ableton Live 4.02, Live 5, Live 6 and Steinberg Cubase SX 2.01.
- Fast envelope settings produce clicks. This one is intended, as it lets you produce some "trashy" sounds.
- The plugin does not work on systems that lack one of these DLLs:
mfc71.dll, msvcp71.dll, msvcr71.dll
System requirements:
- VST Host
Enhancements:
- Curve could produce strange noises when running on multicore CPUs.

Implicit Curves Rev 3.1
A simple tool that will draw complex function curves. more>> A simple tool that will draw complex function curves.
Usually, curves are drawn from an EXPLICIT formula such as y=sin(x) , where y is on one side of the equals sign, and all the stuff to do with x is one the other side.
An IMPLICIT function is of the form F(x,y)=0. Most formulas cannot be written explicitly, but this very simple program allows you to see what something like x*x + y*y +sin(xy) -16 =0 looks like, for example.
The Implicit Curves application was designed to be a simple tool that will draw complex function curves.

With this program you can select a point light-source with the mouse (just left-click where you want when the mouse cross-hairs appear), and you will see the curve created by the envelope of reflected light rays from the surface of the chosen curve.
It achieved by accurately estimating the derivative of the curve at each point the light hits it, from which I calculate the Unit Normal vector to the curve at that point, from which I can work out the correct reflected ray.
Using Catacaustic Curves application you will be able to draw different types of catacaustic curves, depending and according to the input parameters.
