    Find acceleration to stop at target in frictionless 2D space

    It would make sense that a decent method would be to eliminate tangential velocity first, and then solve it as the one dimensional case along the radial line (treating the goal as the centre). So the three stages you describe would be to: Eliminate tangential velocity by accelerating in the...

    Find acceleration to stop at target in frictionless 2D space

    This is a problem that's appeared in a game I am writing, and is a bit beyond the mechanics I can sort-of remember from high school. The context is I have an object in 2D space which has a position p and a velocity u, and a goal position G I want that object to be in as soon as possible. At...

    Combine two pitch, yaw, roll rotations

    Ah yes, I realize now that the conditional is unnecessary. Although restricting the range of the pitch makes sense, the application of this solution doesn't require it, just any valid set of angles. Thanks again!

    Combine two pitch, yaw, roll rotations

    Thank you I like Serena, your help lead me towards the answer. After some more investigating, it turned out the environment I was solving this for was actually using Z \times Y \times X rotations and not Y \times Z \times X, so my final solution was this: Rotation matrix construction: (y, p...

    Combine two pitch, yaw, roll rotations

    Are you suggesting I should convert both of them into quaternions, then find the pitch, yaw, roll from the combined quaternion? Or find the quaternion representation from the combined matrix, then find the pitch, yaw, roll from that quaternion? Would either of those methods be easier than what I...

    Combine two pitch, yaw, roll rotations

    Firstly, I apologise if this is the wrong section, but as far as I could tell this was the most relevant. I have a pair of triplets (p1, y1, r1) and (p2, y2, r2). Each one describes a set of roll, yaw, and pitch rotations in that order, by the angles given by each component in respective order...
