camera movement
I've been working on this for a while, but I don't know what to do for camera movement. I'm thinking some sort of drifting thing that passes above/below the clouds. I haven't touched it in a while, so I don't quite remember how it works.

you need to have a global rotation matrix (regular rotation matrix that is just inverse of regular rotation matrix). then you can do


point = point - camera_position //transform
point = point * rotation_matrix //rotate camera
iz = 1/point.z; //
x = point.x*iz  // convert 3D point
y = point.y*iz  // to 2D

you just have to make sure that camera is looking at same point, which is imo more complicated than figuring out camera.
I can easily be wrong, so correct me if i am :p

Right now it is way too random and bumpy. The onbeat random shift means it always hovers around the same position. This is not just stupid (as you are discarding the majority of the possible view angles) but also annoying because you never show people everything.

looks okay for a scene... but where is the camera movement??? oh wait... reads first post again :p

make it go straight line forward + psuedo random rotation, i really love those classics...

might be good when fixed up :)

edit: dont know if i ever commented but robobot v2 is teh good shit. especially since it features my name in some comments!!! woooo!!! :p
