Morph By Robin Barnes Morph is a full multi-tasking desktop application; when run it installs itself on the icon bar, appearing as a strip of film. Morph takes two sprites and Morphs between the two according to a mesh, the position and shape of which is defined for the initial and final sprites. The mesh consists of interlocking points forming polygons that enclose areas of the screen. Morph outputs a sequence of sprites that can then be animated together (using Convert and Animate) to produce the final sequence. Loading the Sprites =================== Clicking on the icon opens the two editor windows, one called 'Initial sprite' and the other 'Final sprite'. These two windows show the two sprites to be morphed and also the mesh that controls the morph. Load in the two sprites by first dragging the initial sprite onto the appropriate window, and then the final sprite. Any sprite in any mode is acceptable, although the program only operates over a range of one full screen. Once the sprites are loaded, the next stage is to define a morph mesh. It is easiest to experiment with the sprite display switched off; this can be done by pressing Menu over one of the windows and choosing 'Show Sprites' (see later). This makes the mesh much easier to see. Creating a Mesh =============== Anyone familiar with Draw will have no problems with the conventions used in Morph. A mesh consists of an interlocking network of points; mesh elements are defined as polygons of four sides or less. Clicking with Select in one of the windows will produce a small red box signifying a defined point; this will appear in the same place in both windows. Move around the window a little and click Select again and another point will be defined and a grey line will join the two. Clicking on more points will add more lines, when the fourth point is reached the polygon is automatically closed. The polygon can be closed at any point by clicking Adjust. Further clicks with Select will define more polygons, and existing points can be incorporated into new polygons by simply clicking on them. Usually points are coloured blue with black lines joining them and the currently selected point is coloured gold; however when a new polygon is being defined, the currently selected point turns to red and new lines are coloured grey. Clicking Adjust over a point when a polygon is not being defined changes it to the currently selected point, and dragging the currently selected point with Adjust moves it within the window. The position of the point remains unchanged in the other window; this allows either the initial or final mesh to be distorted relative to one another. Click Menu over either of the windows to bring up the editing menu. The entries have the following functions. 'Save': leads to a standard save box that allows a mesh to be saved to disc. A mesh can be reloaded by simply dragging it into one of the windows. 'Show Sprites': toggles whether the sprites are displayed. The 'Point' submenu supplies the main mesh editing functions: 'Delete' deletes the currently selected point. If the point is already part of a defined polygon then the number of sides to that polygon will be decreased by one. 'Delete All': removes the mesh completely. 'Group' and 'Ungroup': these are are very powerful functions. Dragging several points until they overlap and choosing 'Group' will group them together as a single point; this allows sections of the mesh to be stitched together. Note that points grouped in one window will also be grouped in the other. The 'Ungroup' option separates a point that is part of several polygons into a separate point for each. Combining these two tools greatly simplifies defining the mesh. 'Morph': starts the actual morphing process, as described in the next section. The Morphing Dialogue Box ========================= When the 'Morph' option is chosen, the edit windows will be closed and two new windows will be opened. One shows the output sprite, and the other is the morphing control panel. Initially the output sprite window shows a wire frame preview of the morph. The control panel shows how the morph will progress. The program will produce a sequence of sprites, numbered between zero and the value in 'End frame'; the 'Current frame' icon shows which frame in the sequence the morph has reached. Clicking on the arrows or typing in the appropriate box allows these initial values to be changed, and when RETURN is pressed the wire frame preview is updated to show the change. The output mode is limited to one of three 256-colour modes: 13, 15 or 21. Higher resolution sprites will take longer to produce. The 'Dithering' option smoothes the transition of one colour to another but does slow down the processing time. The 'Sprite file' icon shows where to save the output sprites. Either type in a full pathname into the writable icon, or click on the right arrow, type in a filename and drag the icon to a directory. Note that sprites will be created with the frame number appended, so if you are creating, say, 20 frames, then you should only use up to eight characters in the filename. The size of the sprite is specified in OS units so a size of 1280 x 1024 corresponds to a full screen. Making the sprite smaller scales the morph to the appropriate size, and using a smaller sprite also speeds the morph process up and saves disc space. To check that the mesh does enclose all of the relevant sections of the sprite a preview option is available. Pressing Menu over the output sprite and choosing 'Preview' from the menu will make the program produce a sprite that shows which areas of the screen the mesh encloses. The hourglass shows how far the sprite has progressed; for a complicated mesh this can take a couple of minutes so the process can be aborted at any time by pressing Adjust. Once the morph has been set up, clicking on 'Go' sets the process in motion; the output sprite window will be cleared and the sprite will be built up from the bottom. The 'Pause' button will suspend the Morph if clicked. Clicking on 'Cancel' will abort the current morph and return the program to editing mode. To speed up the morphing process the program can be switched to single task mode by choosing 'Single task' from the menu; pressing any mouse button returns to the desktop. The statistics on the current morph are also available from the menu; this indicates how long the morph is taking, how long the current frame is, and the average time to produce a frame. As each frame is completed it is saved to disc under the name given, and the next frame is automatically started. This process continues until all the frames have been completed and saved. Once the sprites have been produced they can be animated using the Convert and Animator applications.
