Sandy engine Study Notes: Preliminary Test of 3D effect

 

 

 

After one morning's study, I felt that the as3.0 released by Sandy was really powerful. I read some official introductions and made it available.

I feel pretty good. I have Paster this image, and the 3D effect has come out. With the camera added, the effect is good.

However, I feel that 3D computing is huge. When I scale up this item, the CPU usage is much higher. If you are interested, you can download the class library from the official website and help documentation.

 

This is not a toy, but flash lovers will remember it.
