Change Log

Version 1.3.0

  • Updated mathbox to https://www.npmjs.com/package/mathbox. Thanks Sam Ritchie! This includes update of ThreeJS to 0.137, which includes significant rendering improvements of transparent surfaces.

Version 1.2.9

  • Made axis "Scale" more visible. It's been moved from the gear settings to main Axis objects.

  • Added functions re, im, conj, and arg for complex number manipulation

  • Fixed #290

    Grid snapping is now turned off by default. Snapping attempts to snap gridlines to "nice" numbers, but can result in incorrect number of gridlines

  • Some README documentation fixes and other fixes, Thanks @nicegamer7

Version 1.2.8

  • Fixed #250
  • Fixed a bug where vector-valued functions sometimes erroneously displayed errors that they had the incorrect number of outputs. This happened with functions that sometimes sampled to complex values, and could cause problems loading graphs.

Version 1.2.7

  • Fixed a bug where newly created folders, if saved in their default state (default title and open) would prevent the saved graph from loading properly.
  • Fixed a bug where Share button's "Copied!" status was not resetting properly.

Version 1.2.6

  • Math3d.org will now prompt users to confirm when leaving the site if their visualization has not been saved, or if they have loaded a previously saved visualization and have made meaningful changes to it.

Version 1.2.5

  • added an Orthographic option for the camera.

    Note: Due to a bug in MathBox, this is not a true orthographic camera, but a perspective camera dollied way out, and zoomed way in ("dolly zoom"), which mimics the effect of an orthographic camera.

Version 1.2.4

  • added hyperbolic trig functions and their inverses, cosh, sinh, tanh, arccosh, arcsinh, arctanh.

Version 1.2.3

  • Fix a bug where vector fields and implicit surfaces would throw errors if an expression named "f(...)" was used as the right-hand-side.

Version 1.2.2

  • Add pdiff function with signature pdiff(f, x, y,..., 1) for the partial derivative of f(x, y,...) with respect to first argument, namely x.
  • Add curl function that accepts 3-dimensional vector fields F(x, y, z) with signature curl(F, x, y, z)
  • Add div function that accepts vector fields F(x, y, ...) with signature div(F, x, y, ...)

Version 1.2.1

  • fixed a bug that caused some successfully loaded graphs to crash when new object added (#200)
  • added inverse trig functions arctan, arcsin, arccos. The arctan function can be called with 1 or 2 arguments.
  • fixed a bug that caused some graphs to crash on load (#190)

Version 1.2.0

  • Updated MathBox to use newer version of ThreeJS. This fixes scrolling/zooming issues in Firefox.
  • Objects are now drawn in order of decreasing opacity
  • Adjusted default width/opacity for axis grids
  • Adjusted default width and zBias for surface gridlines

Version 1.1.1

  • Updated MathQuill to latest version. This fixes a bug where Android virtual keyboard would not type correctly in MathQuill fields.
  • Fixed a bug where app would crash if last folder was deleted.

Version 1.1.0

  • Added color maps for Explicit Surfaces and Parametric Surfaces
  • Decreased drawer width when screen size is small
  • Added more examples
  • Decreased CPU usage when no animations are running (achieved by rendering 30 times fewer frames per second when scene is static)

Version 1.0.0

  • Initial release
