I am assuming you have read all of the help files within the KaleidoPaint iPad App. It’s not very complicated. Go read it. RTFM! Now, if you’ve already read it, read on.
Tip # 1: First thing I do when I start a drawing:
- Choose the type of symmetry to tackle
- Turn on the grid, as as helper to get started
- Set the default background to white
- Move the thickness slider to the left, not quite at its minimum, but close
- Select a neutral, dark grey to sketch with
Tip # 2: To draw an absolutely straight line:
- Make the thickness of the line at least 3/4 of the way possible on the line thickness slider
- Draw the line fast and curt
- Pull up the line editor and reduce the thickness back to the size you need. If there are any unecessary control points, delete them.
The drawing below was built in the P6 symmetry group. It consists of 4 straight lines drawn from the centre of the hexagon, with a thick setting. Try it. Draw them fast. Notice they have only two control points, because they are drawn thick and fast. Makes it easy to adjust them. One short curve is then drawn at the perimeter for the tire, a thick line that stays thick. Once you have that curver relatively uniform, all you need are two dots, one really wide and a lighter grey one on top, smaller, both to draw the wheel hub. Some minor tweaking for locating the spokes properly. Voilà, you have a bike wheel. Guess, if I added a few more control points on the thick tire line, I could take out the bumpy ride! And add knobbies for the tire tread.
Tip # 3: Messy sketches and clean drawings:
- Most of the time my drawings start off very messy. A tangle of lines, and even I can’t see the shapes anymore. In many instances, after I can perceive an idea, but can’t edit (or locate) any of the lines…
- I set-up a thick pen with a weird colour
- I then draw on top of the messy sketch with this very visible line
- It is also visible in the list of editable lines, under the edit button. It will also be the last at the bottom of the edit list. Although the newer versions of KP have the last drawn line at the top. Thanks for that Jeff.
- At this point, it is quite easy to edit the line by dragging, deleting or converting the spline’s control points.
- Once I have a satisfactory outline for my tessellation, and can then delete all the previous sketch lines. Which can get tedious… select-delete, select-delete, select-delete…
- To eliminate the tedious repetitive deletions, you can copy the code file, open it in a text editor and do a mass delete. I’ve had one code file go from 623 pages down to 23 pages with one press of the mouse. Much easier.
Tip # 4: When in Edit mode:
When editing lines, white dots with either a grey outline or a black outline show up. The grey outline refers to a dot with angular line path, whereas the white dot with the black outline, refers to a line with a curved path.
Lots of software out there to help you accomplish tessellation designs.
An iPad app is available, which is what I have used here to create these images: KaleidoPaint by Jeff Weeks.
There is also a java-based program “Escher Web Sketch” at the Ecole Polytechnique de Lausanne. Make sure Java is enabled and not blocked by your security software.
Also, another screen-based software by Anselm Levskaya Escher Sketch v2.
Or a pair of scissors and a piece of cardboard works quite well. That’s how I learned.
