Bug 801: Region Dirty Update; TextureSequence GLMediaPlayer Fix; Blending Fix ;
- Region Dirty Update - Split dirty -> ShapeDirty + StateDirty, where StateDirty forces re-rendering content w/o geometry update as req. for 2-pass mode. - Fix TextureSequence (GLMediaPlayer) usage in RegionRenderer / GLRegion* - handle GL_TEXTURE_EXTERNAL_OES incl. Android ES3 bug - inject TextureSequence's shader stubs - shader: Use abstract lookup 'texture2D' -> 'gcuTexture2D' - flip scaled colorTexBBox if TextureSequence 'tex.getMustFlipVertically()' - TODO: Handle multiple TextureSequence shader programs! - Fix Blending: GLRegion* / RegionRenderer / RenderState - Disable/Enable depth-writing w/ blending - Region impl. sets proper glBlendFunc*(..), i.e. 2-pass: - render2FBO: glClearColor(0f, 0f, 0f, 0f) glBlendFuncSeparate(GL.GL_SRC_ALPHA, GL.GL_ONE_MINUS_SRC_ALPHA, GL.GL_ONE, GL.GL_ONE_MINUS_SRC_ALPHA) - renderFBO: glBlendFunc(GL.GL_ONE, GL.GL_ONE_MINUS_SRC_ALPHA) - User code shall not set glClearColor(..) for 2-pass anymore - Graph-UI Demo - UIShape: - Add MouseGestureListener, combining MouseListener + GestureListener - EventDetails -> PointerEventInfo - PointerEventInfo contains objPos (ray-intersection) and glWin-pos - Toggle: - Separate color (on/off) if enabled - Toggle on click if enabled - SceneUIController - Use PinchToZoomGesture and propagete same gesture to UIShape - Use AABBox.getRayIntersection(..) using 'real' shape coordinates for 1st picking. - Use shape PMV for secondary picking (drag, zoom 2-pointer, etc), see windowToShapeCoords(..) - Sort shapes according to z-value (render: ascending; picking: descending) - Only 'drag' if pointerId matches 1st pressed pointer
