When we speak of performance in a Papervision3D context, we mean everything that relates to how fast Papervision3D can render a scene. Each do3D that is placed somewhere in a scene needs to be calculated. Even when objects are not within the view frustum of a camera, they have a small footprint on the CPU. During each render, Papervsion3D has to decide which triangles are within the view frustum and which triangles are not. Camera-facing surfaces that are placed inside the view frustum have the highest CPU footprint. They need to be projected and then drawn on the screen. Drawing the faces with materials is the most CPU-intensive task.
In order to optimize performance, we first need to know how to measure it. One way to do this is looking at the Activity Monitor on the Mac, or at the processes tab in the Task Manager on Windows. In both utilities, you can look for Flash or the browser used for publishing with Flex Builder or Flash Builder. However, most of the time...
