fruit ninja Blade effect

i want to make fruit ninja blade. i am using cocos2d and the MotionStreak is really ugly for this. Any other ap开发者_如何学JAVAproach or better settings for MotionStreak? maybe particle system? any free great tools similar to ParticleDesigner?

I have my own implementation with OpenGL triangle strips mapped with texture. The blade is very smooth if the distances between adjacent points are small enough. I use linear interpolation to insert more points between two points which the distance is greater than a predefined constant. I'm thinking of use order 2 interpolation but the implementation is more difficult and the performance may reduces. Source code is available here https://github.com/hiepnd/CCBlade

i don't know how much effort it will take but the thing is you can create and change shape of filter and just apply a white to gray gradient as it's texture, it'll give a very good looking results. i myself am working with cocos2d-x (it's just a c++ port of cocos2d) and it has samples for dynamic filters (it's just like you create and manipulate a mesh and all the things are done automaticaly), it uses CCActionGrid class but i just didn't used this class yet if you couln't solve your problem using that ask me to search deeper.
