Papervision3D BitmapEffectLayer

Instructions

Δ

  1. Import import org.papervision3d.view.layer.BitmapEffectLayer;
  2. Declare private var layer :BitmapEffectLayer;
  3. Initialize layer = new BitmapEffectLayer(viewport, w, h, transparent, fillColor, clearMode, renderAbove, clearBeforeRender);
    Parameter: Default: Description:
    viewport NONE viewport
    w 640 width
    h 480 height
    transparent true background transparency
    fillColor 0 background color
    clearMode "clear_pre"
    renderAbove false
    clearBeforeRender false
  4. Add effect layer.addEffect(effect);
  5. Add layer viewport.containerSprite.addLayer(layer);
  6. Add object layer.addDisplayObject3D(object);
