Performance Stats (Rate) Menu

The Performance Stats menu is accessible from the Rate indicator on the menu bar and appears as follows:

The Performance Stats menu contains informational entries about the complexity of the current MotionSampler database.

Rate

The top entry in the menu, Rate: 0.00, is the current value of the image display rate. This is not related to the actual frame rate used for the recording or sample rate. The number listed at Rate is a measure of how often the hardware can redraw the current scene.

The rate is updated about once per second during continuous redraw (such as playback or tumble). When the Rate is being updated, it is in roman text as follows:

When Rate is no longer being updated, it is displayed in italics as follows:

Polygons

The Polygons value represents the number of polygons in the model. If the model is modified, a different number of polygons is displayed.

Vertices

The Vertices value represents the number of vertices in the model. If the model is modified, a different number of vertices is displayed.

Numbers of polygons and vertices provide a good indication of the complexity of your model and are directly related to the redraw time. Models made up of several thousand polygons should display at 15 frames/ second on Indigo2 class machines. Polygon and vertices counts above 10, 000 can lead to slow display. Sometimes, displaying the model as a wireframe or as points results in sufficient drawing speed for data capture.

Graph Nodes

The Graph Nodes value represents the number of graph nodes in the model. If the model is modified, a different number of graph nodes is displayed.

The Graph Nodes count is a reflection of the complexity of the internal structure created by MotionSampler to approximate the dag structure found in Alias. Very complex structures may result in slow redraw.
