Performance Comparison Between pv3d and away3d

Because the project needs to use Flash to develop 3D animation, it reminds me of the several popular Flash 3D libraries that I never knew where to find PV3D and Away3D, it is said that PV3D has high performance but is not flexible. Away3D is flexible but has low performance. Performance is indeed a very important factor to consider, the performance of the two is poor, there is no ready-to-use answer on the Internet, so you can do it yourself. It took some time to run the successful PV3D and Away3D examples and then start the test:

Test content: displays the rotated sphere. The sphere surface is divided into 20000 triangles and the radius is set to 200. Do not use light.

Flash size: 800*600, fps: 30, LOW quality.

PV3D measured value: 15.6 fps

Away3D measured value: 4.23 fps

Although the performance of both can only be described as unsightly, The 15fps of PV3D is also tolerable considering that it is not used to develop 3D games with flash.

PS: PV3D forgot to set the quality. flash is set to HIGH by default, but the performance gap is so obvious that changing to LOW will only increase the gap.
