• ## Creating a Pattern as an Inkscape Extension: Part 4

Continuation of Part 3 STEP 8: ADD CONTROL POINTS AND CREATE THE CURVES Curves are stored in SVG files as bezier curves.  Bezier curves in Tau Meta Tau Physica are defined with 4 points: a start point, two control points and an end point. If you use Inkscape to look at a curve in any SVG…

Continuation of  Part 2 STEP 6: CREATE THE SVG OBJECTS The formulas we’ve written calculate the x,y coordinates for each point. They don’t create the SVG elements that we see on the Inkscape canvas. If we wrap each of these formulas with a function that creates an SVG element, then we calculate the pattern point coordinates…

• ## Creating a Pattern as an Inkscape Extension: Part 2

Continuation of Part 1   Here is the pattern with the new points added: STEP 4: RENAME THE POINTS The next step is to convert each point into a naming convention. The pattern pieces are single capital letters. The Front Bodice will be pattern piece A, the Back Bodice pattern piece B.  All points for the Front…

• ## Creating a Pattern as an Inkscape Extension: Part 1

This diagram and the instructions below were re-created from Practical Sewing and Dressmaking, Sara May Allington, Boston: Dana Estes and Company, 1913. 1. Draw Line A-B length of Back Length measure. 2. From A measure on line A-B Underarm measure. Mark this point C. 3. At C square a line with A-B. 4. From C measure on…

• ## Basics: Variables in TMTP

The basic data object in TMTP is the point. A point is a python object with these three attributes: x       : the x coordinate of the point y       : the y coordinate of the point name: the name of the point The names are very simplified, because there can be over 100…
