You can move the angle of the light and add or subtract texture and also adjust the hue and saturation for a change in color.
The angle of repose — the steepest angle that loose rocks can abide before they start to move, the steepest angle the soil can maintain before it starts to fail — will vary locally according to the mechanics of shape and strength.
We put the incident angle to the minimum (the Sun in nadir position with respect to the surface) and moved the emission angle from the minimum (13°) to 20° and then to 80°, step 10°. Figure 8 shows the measurements (we show 1−R, R = reflectance, for a direct comparison with emissivity) for Millbillillie, and Fig. 9 shows the reflectance measured for synthetic enstatite.
Those constraints are that when the crane is moving, the swing angle has to be small; the swing speed has to be slow, and the moving force is limited.
Imagining a simple Lewis-like structure, varying this angle moves the lone pair of electrons away from a linear extension of the intramolecular bond between the halogen atoms and thus acts as a probe of the directionality of the intermolecular halogen bond.
Vortex pinning, guided vortex motion, and the ratchet effect are three main fluxonic "tools" which allow for the dynamical (pinned or moving), the directional (angle-dependent), and the orientational (current polarity-sensitive) control of the fluxons, respectively.
Then, let α o =argminα ∣ f i −1 α, p′(O i −1))− p(O i −1)∣ be the flanking rotation angle that moves the backbone O of peptide i−1 to the point closest to its original position.
The left side controls direction; the joystick on the right moves the blade up, down or angles it for a cross-slope.
The sky scanner is programmed to look into the opal glass of the calibration laser source by moving to the angle coordinates of an elevation angle of 180° and the azimuth angle corresponding to the direction to the calibration chamber.
When the sea sapphires move, the angle of light produces a colorful reflective effect, with different-sized crystal layers in different species resulting in a variety of hues.
