Version 0.11.0

Add core functions:

• getChordHeight(): Gets the height of a chord given the radius and the angle
• getChordDistance(): Gets the distance to a chord given the radius and the length

Improve the render script utils:

• spawn several processes when rendering multiple files

Version 0.6.0

Add core functions:

• vangle(): Computes the angle between two vectors.
• getAngle(): Computes the angle of a point on a circle.
• vertexAngle2D(): Computes the vertex angle given three 2D points.
• vertexAngle3D(): Computes the vertex angle given three 3D points.
• vertexOutline2D(): Computes the outline of a vertex at the given distance from the edges.
• outline(): Computes the outline of a polygon. The outline can be at a particular distance.
• getPolygonAngle(): Gets the angle value at a particular index in a regular polygon.
• lineAdd(): Adds a value to each point of a line.
• simplePolyhedronFaces(): Builds a vector of faces to be used in a polyhedron. The function accepts the number of points defining one main face of the polyhedron, then returns the faces vector that contains the indices of each face enclosing the solid. This only apply on simple polyhedron where two opposite faces share the same number of points.
• simplePolyhedronPoints(): Composes a list of points to be used in a simple polyhedron.
• sizeCross(): Computes the size of a cross shape.
• sizeCrossBox(): Computes the size of a cross shape.
• drawCross(): Computes the points that draws the sketch of a cross shape.
• quadrant(): gets a point on a particular quadrant.

With the add of vangle() and getAngle(), the following functions have beed updated:

• angle2D() and angle3D() now make use of vangle() to compute the angle instead of directly applying the formula.
• tangent2D(), isosceles2D(), protractor() now make use of getAngle() to compute the angles. The biggest change is on the protractor() that should always return a positive value within the 0..360 range.

Add 2D shapes:

• regularCross: Creates a cross at the origin.

Add 3D shapes:

• regularCrossBox(): Creates a cross box at the origin.
• simplePolyhedron : Creates a simple polyhedron, where only two opposite faces are defined by a list of points.

Add operators:

• repeatShape2D(size, count=1): Repeats horizontally a shape on two directions, the interval is set by the shape size. An option allows to center the repeated shapes in repeatShape operators, false by default.
• repeatShape3D(size, count=1): Repeats a shape on three directions, the interval is set by the shape size. An option allows to center the repeated shapes in repeatShape operators, false by default.

Features:

• Filter the extension from the name of the package to test. Now the test script accept the name of a package with or without the extension. So both commands are now equivalent:

  ./scripts/test.sh core/vector-2d
  

  ./scripts/test.sh core/vector-2d.scad
  

Fixes:

• Fix non manifold issue in simplePolyhedron. The issue was due to a counter clock wise order used to define faces.
• Fix typo in the name of function pythagoras() (was pythagore() before)

Improvements on the core function path():
