afqb.three.initAndAnimate(error)

Combine the init and animate function calls for use in d3.queue()

Arguments

  • error – error passed through from previous function in d3.queue()

afqb.three.buildthreeGui(streamlinesExist)

Build the dat.gui controls for the anatomy panel

Arguments

  • streamlinesExist – boolean to indicate existence of anatomy streamlines. if streamlinesExist is true, then the fiberRepesentation controller will allow both ‘core fiber’ and ‘all fibers’ options. Otherwise, only ‘core fiber’ will be allowed.

afqb.three.init(streamlinesCallback)

Initialize the three.js scene for subject’s anatomy

The scene consists of six object groups:

  • afqb.three.brain: the brain surface, loaded from freesurf.OBJ

  • afqb.three.colorGroup: fiber bundle streamlines that display when selected, one object for each bundle

  • afqb.three.greyGroup: grey fiber bundles that are always displayed underneath the color ones, all rendered together as one buffer geometry

  • afqb.three.colorCoreGroup: core fibers that display when selected, one object per bundle

  • afqb.three.greyCoreGroup: grey core fibers that are always displayed underneath the color bundles

  • afqb.three.convexGroup: invisible convex hulls, one for each streamline colorGroup. These are never displayed but hold all of the dom events for the colorGroup objects.

Arguments

  • streamlinesCallback – function to be called after the streamlines have been loaded from streamlines.json

afqb.three.onWindowResize()

Resize the three.js window on full window resize.

afqb.three.animate()

Define how the scene should update after init.

Pretty standard here: request animation frame, render, update camera, update stats if desired. If brushing, use afqb.three.brushOn3D to change the drawRange of color objects.

afqb.three.brushOn3D()

Update the drawRange of each fiber bundle based on the d3 brushes in the 2D plots panel.

afqb.three.lightUpdate()

Update the directional light to always point from camera

afqb.three.makeInvisible(object)

Visibility toggle function to show/hide core fibers vs streamlines

Arguments

  • object (object) – the object to hide

afqb.three.makeVisible(object)

Visibility toggle function to show/hide core fibers vs streamlines

Arguments

  • object (object) – the object to show

afqb.three.highlightBundle(state, name)

Highlight specified bundle based on left panel checkboxes If state is checked, show the color group and hide the grey group

Arguments

  • state (string) – checkbox state, checked or unchecked

  • name (string) – formatted bundle name

afqb.three.mouseoutBundle(child)

Restore bundle to original state (checked or unchecked) after mouseout

Arguments

  • child (string) – the child object (i.e. bundle) in some group

afqb.three.mouseoverBundle(child)

Highlight specified bundle based on mouseover

Arguments

  • child (string) – the child object (i.e. bundle) in some group
