Time Response Graph Tutorial

The RotoView app allows you to experiment with various time response graphs provided by INNOVENTIONS, as well as to design your own. Time response graphs are an important part of the RotoView NLDR algorithm. Based upon the mapping setup, these graphs will dynamically change the relative intensity of the RotoView response to the orientation data.

Tutorial 2.1: Selecting a Time Response Graph

In the default state, the RotoView app uses 'graph1'. This tutorial shows you how to select and review other graphs.

Step 1. Tap More to reach the Setup menu. While the menu shows the current graph name (e.g. graph1) you need to use the Graph Editor as shown in the next step.

Step 2. Tap the Graphs tab at the bottom to reach the Graph Editor menu. The current time response graph is shown together with its description.

Step 3. Tap Select to review the available graphs. Each graph appears with a short description.

Step 4. Tap any graph you wish to select, and press Accept to confirm your selection. The newly selected graph will now appear.

Step 5. Tap the top right RotoView button to return to the main view.

Step 6. Navigate your photo to see the graph's behavior. You can also change the graph mapping as described in Tutorial 2.2.

Tutorial 2.2: Change the Time Response Graph Mapping

The RotoView time response graphs provide a normalized mapping of view navigation rates (intensity) for 10 time slots. This normalized time must be mapped to either a fixed mapping time or to the exit time determined by the exit method setup (if that parameter is set).

Step 1. Tap More to reach the Setup menu.

Step 2. Scroll down to the Time Response Graph Mapping group. Tap the Intensity scale factor or the Map graph's time to to reach the Graph Mapping menu.

Step 3. Change the intensity scale factor. It is normalized to the value of 10, so that selecting 5 will decrease the intensity by two, and setting 20 will increase the intensity by two.

Step 4. Set the length of time you want to map the current graph. If the automatic exit is set, you can map the length of time to the exit time value.

Step 5. Tap the top right RotoView button to return to the main view.

Step 6. Navigate your photo to see the graph's behavior. Note that if your navigation time exceeds the mapping time, the navigation uses the last value of the graph for the remainder to the navigation.

Tutorial 2.3: Create your own Time Response Graph

Step 1. Reach the graph selection view of the Graph Editor as described in Tutorial 2.1, and tap the New button on the top right. This will activate the graph design view, using the current response graph.

Step 2. You can reset the graph to start with a flat graph or use the current response graph as a start. Change the graph by dragging any of the 10 points. Changes are made along the vertical (intensity) exit. Your graph time is mapped in accordance with Tutorial 2.2. Remember that if navigation time exceeds the mapping time length, the navigation continues with the intensity of time 9.

Step 3. Once completing your graph, you can abort the changes or select SaveAs to use your new graph.

Step 4. Please enter a short description of your graph. This will be handy when you try to select different graphs.

Step 5. You can save your graph as either 'user_graph1', 'user_graph2' or 'user_graph3'. Saving the graph will erase any previously stored graph.
