Trafffic ideas.. anyone?

Hi,

I had look into it.. and now I know why it didn't work in the first place. I was missing a funtion to generate the control point also I didn't specify time, that's why Vizard was complaining about missing arguments.

I will look into viewpoint tutorial later. Thanks for pointing out where I went
wrong!

Hi,

I got the script working with lots of tweaking. The value of x, y, z in Blender translates as x, z, y in Vizard. With my control points in OSG format I have to make it as x, -z, y in vizard, with other format.... different xyz coordinates.

It runs. It works fine. Now in my huge environment, I have 1200 control points that the camera will have to go though. I used viz.CUBIC_BEZIER and viz.BEZIER but none of them give me smooth curve results. It seems like at every single control points the camera tends to jerk a little bit before moving to the next control point.

i.e between point 1 to point 2 the animation is smooth, but by the time it hits point 2 the camera angle move quickly to the direction of point 3. This quick movement doesn't blend from the previous camera orientation smoothly.

Is there another method to get a smoother result? perhaps cubic_bezier on top of cubic_bezier?



Thank you,

Okay, we did something to smooth out our path animation with "<path>.autorotate" enabled.

It was like this, create a path that composed of lots and lots of nodes (as required), attach camera and a quad/polygon (make this invisible later) on the same path. Then, during animation play, get the quad to run about 1-3 nodes/control points in advance before the camera animation starts. and set the camera to "lookat" the quad.

the only drawback is... after 1st or 2nd lap, somehow the quad is behind the camera therefore, going backwards. A coding problem from our end, I'm sure.

anyway... hope this helps anyone who's working out with path animation.
