constructor

• new IfcTransparencySettings(_viewer: TwinfinityViewer): IfcTransparencySettings

• Parameters

  • _viewer: TwinfinityViewer

  Returns IfcTransparencySettings

Accessors

publicmode

• get mode(): TransparencyMode
• set mode(transparencyMode: TransparencyMode): void

• Gets the currently active mode of transparency

  ---

  Returns TransparencyMode

• Changes how transparency is handled for transparent IFC objects

  ---

  Parameters

  • transparencyMode: TransparencyMode

    The type of rendering that will be used for all transparent IFC objects, dithering means that pixels are rendered opaque but skipping every few pixels in a screen pattern depending on the opacity Seethrough is normal alpha blending

  Returns void

Methods

publicsetDitheringDepthDiscardMode

• setDitheringDepthDiscardMode(ditherDiscardDepth: boolean): void

• Set the currently used dither mode for solid objects that are dithered, and transparent objects if the transparency mode is dithering

  ---

  Parameters

  • ditherDiscardDepth: boolean

    Wheter or not to discard fragments in the depth shader that are dithered, this is needed for transparent objects to not write to the depth buffer

  Returns void

publicsetDitheringMode

• setDitheringMode(ditherMode: DitheringTextureMode, animatedFrames: number): void

• Set the currently used dither mode for solid objects that are dithered, and transparent objects if the transparency mode is dithering

  ---

  Parameters

  • ditherMode: DitheringTextureMode

    What dithering mode to use, bayer uses a bayer matrix to determine which pixels to render opaque, blue noise uses a blue noise texture

  • animatedFrames: number

    How many frames to use for the dithering animation when moving the camera, if 1 then no animation is used. Works best with Blue Noise

  Returns void
