  • virtual void GLRender (SoGLRenderAction *action) β€” the render call, and it's virtual, so it's giving main character energy when the GL render action comes through.

πŸŽ€ okay that's the whole first half bestie β€” there's more coming, so don't wander off, part 2 is right there πŸ’–

πŸ’– Detailed Description πŸ’–

The SoVRMLMovieTexture class is literally the way to map movies onto geometry. Bestie, we're putting actual video on your 3D shapes. Iconic behaviour.

The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:

MovieTexture {
  exposedField SFBool   loop             FALSE
  exposedField SFFloat  speed            1.0      # (-inf, inf)
  exposedField SFTime   startTime        0        # (-inf, inf)
  exposedField SFTime   stopTime         0        # (-inf, inf)
  exposedField MFString url              []
  field        SFBool   repeatS          TRUE
  field        SFBool   repeatT          TRUE
  eventOut     SFTime   duration_changed
  eventOut     SFBool   isActive
}

So the MovieTexture node defines a time dependent texture map (the one chillin' inside a movie file) plus all the parameters for controlling both the movie and the texture mapping. And here's a lil plot twist πŸ‘€ β€” a MovieTexture node can also be used as the source of sound data for a Sound node. In that special case, the MovieTexture node is not used for rendering. It's giving audio-only era.


Texture maps are defined in a 2D coordinate system (s, t) that ranges from 0.0 to 1.0 in both directions. The bottom edge of the image corresponds to the S-axis of the texture map, and the left edge of the image corresponds to the T-axis of the texture map. The lower-left pixel of the image corresponds to s=0.0, t=0.0, and the top-right pixel of the image corresponds to s=1.0, t=1.0. Figure 6.12 depicts the texture map coordinate system of the MovieTexture.

Figure 6.12 -- MovieTexture node coordinate system

The url field that defines the movie data shall support MPEG1-Systems (audio and video) or MPEG1-Video (video-only) movie file formats 2. Details on the url field can be found in 4.5, VRML and the World Wide Web (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.5).

MovieTexture nodes can be referenced by an Appearance node's texture field (as a movie texture) and by a Sound node's source field (as an audio source only). See 4.6.11, Texture maps (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.11) for a general description of texture maps. 4.14, Lighting model (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.14) contains details on lighting equations and the interaction between textures, materials, and geometries. Slay, the whole lore is linked. πŸ“šβœ¨

As soon as the movie is loaded, a duration_changed eventOut is sent. This indicates the duration of the movie in seconds. This eventOut value can be read (for instance, by a Script node) to determine the duration of a movie. A value of "-1" implies the movie has not yet loaded or the value is unavailable for some reason. Not me waiting on a -1 like it's a text back 😭

The loop, startTime, and stopTime exposedFields and the isActive eventOut, and their effects on the MovieTexture node, are discussed in detail in the 4.6.9, Time-dependent nodes section (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.9).

The cycle of a MovieTexture node is the length of time in seconds for one playing of the movie at the specified speed. The speed exposedField indicates how fast the movie shall be played. A speed of 2 indicates the movie plays twice as fast. The duration_changed output is not affected by the speed exposedField. set_speed events are ignored while the movie is playing. A negative speed implies that the movie will play backwards. πŸ”„ (yes queen, reverse playback, we love a plot twist)

If a MovieTexture node is inactive when the movie is first loaded, frame 0 of the movie texture is displayed if speed is non-negative, or the last frame of the movie texture is shown if speed is negative (see 4.11.3, Discrete and continuous changes). A MovieTexture node shall display frame 0 if speed = 0.

For positive values of speed, an active MovieTexture node displays the frame at movie time t as follows (i.e., in the movie's local time system with frame 0 at time 0 with speed = 1):

t = (now - startTime) modulo (duration/speed)

If speed is negative, the MovieTexture node displays the frame at movie time:

t = duration - ((now - startTime) modulo |duration/speed|)

When a MovieTexture node becomes inactive, the frame corresponding to the time at which the MovieTexture became inactive will remain as the texture. Frozen mid-vibe, honestly relatable. πŸ’…

SoType SoVRMLMovieTexture::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class.

SoType SoVRMLMovieTexture::getTypeId (void ) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Reimplemented from SoVRMLTexture.

const SoFieldData ** SoVRMLMovieTexture::getFieldDataPtr (void ) [static], [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. (iykyk β€” stay out of the group chat unless you're on the dev team πŸ’€)

Returns the SoFieldData class which holds information about fields in this node.

const SoFieldData * SoVRMLMovieTexture::getFieldData (void ) const [protected], [virtual]

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoVRMLTexture.

void SoVRMLMovieTexture::initClass (void ) [static]

(no description, bestie β€” it's just out here doing its job quietly πŸ™ˆ)

void SoVRMLMovieTexture::GLRender (SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.

Reimplemented from SoVRMLTexture.
