πŸ¦‹ SoWWWInline πŸ¦‹

okay so welcome to SoWWWInline(3IV), bestie πŸ’– this is the manual page for a node that is literally like "my children are on the internet, go get them" and honestly? iconic.


🌸 NAME 🌸

SoWWWInline β€” a node that refers to its children through a URL. yes, a URL. the whole vibe is remote children. no cap.

πŸŽ€ INHERITS FROM πŸŽ€

SoBase > SoFieldContainer > SoNode > SoWWWInline

so she's a whole descendant of SoBase, through SoFieldContainer and SoNode, down to SoWWWInline herself. royal lineage fr fr πŸ‘‘

✨ SYNOPSIS ✨

first, the include, because you always need the include:

#include <Inventor/nodes/SoWWWInline.h>

then the callback typedef:

typedef void        SoWWWInlineFetchURLCB(const SbString &url, void
                         *userData, SoWWWInline *node)

and then this enum, which is all about when the bounding box gets shown:

enum BboxVisibility {
     SoWWWInline::NEVER         Do not show bounding box
     SoWWWInline::UNTIL_LOADED  Show bounding box (if specified) until
                                     data is loaded
     SoWWWInline::ALWAYS        Show bounding box along with data
}

so, translated for the girlies:

  • SoWWWInline::NEVER β€” do not show the bounding box. not ever. she's hidden. πŸ™ˆ
  • SoWWWInline::UNTIL_LOADED β€” show the bounding box (if one was specified) until the data is loaded, then it dips ✌️
  • SoWWWInline::ALWAYS β€” show the bounding box along with the data, forever, main character energy πŸ’…

🌟 DESCRIPTION 🌟

so here's the tea, bestie: this node refers to its children through a URL (that's a Universal Resource Locator, iykyk). and the plot twist is that the node does not go get the data itself. the application is the one responsible for actually fetching data from the URL for an SoWWWInline node to display. so it's like, the node is pointing at the snack, but your app is the one walking to the fridge. periodt.

πŸ’… FIELDS πŸ’…

  • SoSFString name β€” specifies the URL that the application should fetch as child data for this node (e.g. "http://bogus.com/homeWorld.wrl.gz"). yes bestie that example URL is literally in here and I love that for us.
  • SoSFVec3f bboxCenter β€” defines the center of the bounding box surrounding the URL child data.
  • SoSFVec3f bboxSize β€” defines the size of the bounding box surrounding the URL child data.
  • SoSFNode alternateRep β€” specifies child data that can be used instead of fetching data from the URL. on read, if this field is set and there is no fetch URL callback registered, the alternateRep will be used as the child data. otherwise, it is the application's responsibility to set the child data (see setChildData()). so she's the backup plan, the understudy, the one who goes on when the URL doesn't show up 🎭

πŸ”₯ METHODS πŸ”₯

SoWWWInline()

creates an inline node with default settings. brand new, default settings, fresh out the box ✨

static SoType getClassTypeId()

returns the type identifier for this class.

void setFullURLName(const SbString &url) / const SbString & getFullURLName()

okay so if the name field contains a relative URL (like "foo.wrl" instead of "http://bogus.com/foo.wrl"), the inline cannot resolve the URL reference β€” it just can't, bestie, it doesn't have the range. this method lets the application tell the anchor what its full URL should be. and getFullURLName() returns the fullURL that was set here, or, if it was not set, it returns the contents of the name field. fallback queen πŸ‘‘

SoGroup * copyChildren() const

returns a copy of the hidden children as a Group. the children are set by the application through setChildData().

void requestURLData()

requests that URL data be fetched. this will invoke the application callback to actually fetch the data, and it can be called before the inline does this for itself (see setFetchURLCallBack()). so you can jump the queue, no problem πŸ’…

SbBool isURLDataRequested() const / SbBool isURLDataHere() const

returns whether URL data has been requested, and whether that data is here β€” i.e. whether setChildData() has been called. it's giving "did you ask?" and "did it arrive?" 🫢

void cancelURLDataRequest()

cancels the active URL data fetch request. not me calling it off 😭

void setChildData(SoNode *urlData) / SoNode * getChildData() const

set/get the child data that the inline should display. the application should set child data after it has fetched data for an inline node. so fetch first, then set. order matters, bestie.

static void setFetchURLCallBack(SoWWWInlineFetchURLCB *f, void *userData)

the application callbacks that get invoked when the inline needs its URL data fetched. this happens:

  1. the first time the inline is rendered, or
  2. if it needs to compute a bounding box and the bboxSize field is not set, or
  3. when requestURLData() is called.

three triggers, three reasons to be summoned 🌸

static void setBoundingBoxVisibility(BboxVisibility b) / static BboxVisibility getBoundingBoxVisibility()

this allows the application to specify when bounding boxes are displayed. the bounding box can be rendered along with the children (ALWAYS), only until the child data is loaded (UNTIL_LOADED), or not at all (NEVER). default is UNTIL_LOADED. πŸ’–

static void setBoundingBoxColor(SbColor &c) / static const SbColor & getBoundingBoxColor()

this allows the application to specify the color of the bounding boxes displayed. customize her. slay.

πŸ‘‘ ACTION BEHAVIOR πŸ‘‘

  • SoGLRenderAction β€” this renders the child data if it has been set by the application. it will render a wireframe bounding box as specified by the bboxCenter and bboxSize fields, and the setting passed to setBoundingBoxVisibility(). and if no fetch URL callback is set and the alternateRep is not NULL, the alternateRep will be rendered until child data has been set. so the backup plan gets her moment on screen. we love to see it 🌟

🧚 FILE FORMAT/DEFAULTS 🧚

WWWInline {
     name          "<Undefined file>"
     bboxCenter    0 0 0
     bboxSize      0 0 0
     alternateRep  NULL
}
ngl bestie, default name is literally "<Undefined file>" which is the most ominous placeholder text ever πŸ’€ that's just how it ships though.

and that's the whole page, bestie πŸ’œ this was the SoWWWInline(3IV) manual β€” and yeah, the footer at the very bottom is just SoWWWInline(3IV)() again, the same as the header, so there's no extra version number or date hiding down there for us. cute of her to keep it mysterious, honestly. go forth and fetch those URLs 🫢✨
