It is called the axis because the uppermost cervical vertebra (called the atlas) rotates about the odontoid process of C2. An object may have more than one rotational symmetry for instance, if reflections or turning it over are not counted, the … WikipediaĪxis - The axis is the second cervical vertebra (symbol: C2). Rotational symmetry - Generally speaking, an object with rotational symmetry is an object that looks the same after a certain amount of rotation. Rotational spectroscopy or microwave spectroscopy studies the … Wikipedia Frequency is on the x axis, and absorbance on the y axis. Rotational spectroscopy - Part of the rotational vibrational spectrum of carbon monoxide (CO) gas (from FTIR), showing the presence of P and R branches. Rotational diffusion is the counterpart of translational diffusion, which maintains or restores the… … Wikipedia Rotational diffusion - is a process by which the equilibrium statistical distribution of the overall orientation of particles or molecules is maintained or restored. The motion depicted in the animation is for the idealized situation that the… … Wikipedia The animation on the right shows a simple example. Rotational-vibrational coupling - occurs when the rotation frequency of an object is close to or identical to a natural internal vibration frequency. Rotational speed tells how many complete rotations (i.e. Rotational speed is equivalent to angular speed, but with different units. This topic is kind of math-heavy, so you might want to get your linear algebra basics straight, do a little research on quaternions, gimbal lock and the like to fully appreciate using quaternions for rotations.Rotational speed - (sometimes called speed of revolution) indicates, for example, how fast a motor is running. Quaternions for rotations are unit-quaternions (4D vectors), which makes calculating rotations around arbitrary axes efficient, stable and flexible, although a little intransparent because it's hard to visualize the operations. Or you could live with the Euler angles and gimbal lock or choose a different rotation method. You _could_ use quaternions for rotations, convert them to a rotation matrix and then apply that matrix (or use the angle-axis representation). You're experiencing a gimbal lock because you seem to use the Euler angles. If you do Euler angles rotation (as you seem to be doing), you want to pay very close attention to the order of rotations since they make a difference. Just try to switch the order and see what happens. Whether you want to first translate and then rotate or do it the other way around depends. Especially hierarchical structures benefit from that. This keeps all matrix operations for your dynamic objects in separate matrices, so you effectively get local coordinate systems and after you pop, further operations apply to the matrix you worked on before pushing. To act on a local matrix, do a glPushMatrix(), perform your transformation, your rotation and your draw calls and then do a glPopMatrix().
