Adding Images

Movies can be made more expressive with the possibility to add images. One or more images can be associated with a state using the State Bitmaps pane (see snapshot below), which can be invoked by clicking the Bitmap icon in the toolbar of the Movie Studio window. Images can be embedded in a movie in two ways:

An image can be added to the currently selected state by clicking the "+" selection button (see snapshot above). An existing image can be removed by selecting it in the current state's Images list followed by a click on the "-" button. The Remove All button allows to delete all images associated with the current state. If the Bitmap in 2D plane option is checked, the new image will be used in viewpoint-ignoring mode as described above. When the option is turned off (default), the image will follow viewpoint transformations as described above.

The snapshot above shows a state with an added image ("Frame_MentalNavigation.png") in the viewpoint-aware "virtual screen" mode. Note that the image is drawn in 3D space in front of the head and brain meshes. If the scene viewpoint changes, the "virtual screen" position will be transformed accordingly staying in a fixed position relative to the other objects in the scene.

The position of images can be adjusted in the scene by changing the values in the Up/down shift and Left/right shift values in the State Bitmaps pane (see right lower part in the snapshot). The distance of the virtual screen to the rendered meshes can be adjusted using the Distance spin box. The size of a displayed image can be adjusted by changing the Display size value, which corresponds to the millimeter space used by the cortex meshes. Note that the size value will be applied to the width of an image while the height value will be calculated automatically using the aspect ratio of the image.

The 3D Viewer in the snapshot above contains the VMR Volume Slicing panel (used to prepre an axial slice plane) and the Mesh Toolbox that one usually does not want in a rendered movie. When exporting calculated frames as an image sequence or movie file, these panels will be hidden automatically.
