They have one single simple eye that only senses the presence and direction of light.

This new style was focused on changing the direction of light in the painting.

"Dad would always comment about whether the direction of light was consistent or not.

The device also included separate doors at the back which allowed the user to control the degree and direction of light.

The effects of the original direction of light are minimized.

The direction of light is adjustable as the torch rests on a pivot.

Anisotropic crystals will have optical properties that vary with the direction of light.

The illumination angle is the angle between the inward surface normal and the direction of light.

This system also provides maximum light exposure for all the floral clusters, since they are growing from a plane perpendicular to the direction of light.

An optic axis is the direction of light that travels at 0 birefringence, causing the mineral to appear isotropic.

Digital pottery allows you to mold a vase, examine it from any angle, change its color and the kind and direction of light illuminating it.

Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light.

While one uses a type of fishnet of metal layers to reverse the direction of light, the other uses tiny silver wires.

The species does not have a crystalline eye lens, rendering it effectively blind, although it may still be able to detect the intensity and direction of light.

All shading algorithms need to account for distance from light and the normal vector of the shaded object with respect to the incident direction of light.

The thorax and forewings are lustrous and of varying colour, according to the direction of light ranging from greenish golden to a brilliant reddish bronze.

Eyeglass lenses change the direction of light entering the eyes so that it focuses properly on a special part of the back of the eye known as the retina.

The Lytro camera captures the direction of light, producing images with multi-dimensional space, allowing photographs to be refocused and perspective to be shifted after they have been taken.

Although the sketch lacks the palm and roses, essential compositional modes are already in place, with emphasis on Cook's neck, the color of the dress, direction of light, and general design.

Developing an optical system that can discriminate the direction of light to within a few degrees is apparently much more difficult, and only six of the thirty-something phyla possess such a system.

For a fixed composition such as calcium carbonate, a crystal such as calcite or its polymorphs, the index of refraction depends on the direction of light through the crystal structure.

The human eye-brain system has no sensitivity to the vibration directions of light, and polarized light can only be detected by an intensity or color effect, for example, by reduced glare when wearing polarized sun glasses.

To the sky studies he added notes, often on the back of the sketches, of the prevailing weather conditions, direction of light, and time of day, believing that the sky was "the key note, the standard of scale, and the chief organ of sentiment" in a landscape painting.

By that time, Reinitzer had discovered and described three important features of cholesteric liquid crystals (the name coined by Otto Lehmann in 1904): the existence of two melting points, the reflection of circularly polarized light, and the ability to rotate the polarization direction of light.

One is geodetic precession: the axis direction of a gyroscope in free fall in curved spacetime will change when compared, for instance, with the direction of light received from distant stars-even though such a gyroscope represents the way of keeping a direction as stable as possible ("parallel transport").
