Translucent panels are light transmitting. OPAQUE panels are non light transmitting. However, no fiberglass panel should be considered to be light excluding (such as for darkrooms) as glass fibers always have the potential of allowing small amounts of light through. Opaque FRP panels may contain specific fillers to insure low light transmission.

These categories are somewhat qualitative. We ask for your best judgement. The distinction is easiest to explain for an overcast day. If you cannot even tell where the Sun is, you have opaque clouds. If you can see the Sun but it is just a brighter spot that does not hurt your eyes, you have translucent clouds. If the Sun can be seen as a bright circle you have transparent clouds.

Transparent media such as air, water, glass, and clear plastic allow light and images to clearly pass through the material. Translucent materials, on the other hand, allow light to pass through, but clear images cannot be seen through them. For example, frosted glass and thin paper are translucent because they let some light through, but are not transparent because you cannot see clearly through them. See similar questions...

The instruments on board the satellites are able to detect the visual opacity of the clouds by measuring the optical depth of the cloud. The optical depth is a measure of the visual or optical thickness of a cloud. Unlike height, it is not measured in meters or feet; but is nondimensional. Usually we can tell when the satellites are not functioning because they will give us weird information. See similar questions...

Fiberglass panels are translucent, glass is transparent. Both transmit light, but you can not see details through a translucent panel like you can glass or thermoplastic sheeting. Likewise, you do not get direct sunlight, glare, or as many UV rays through a translucent panel. See similar questions...

In the paper industry, "vellum" is a term used to describe a paper with a smooth surface, not the degree of transparency. On our site we've used the more correct term, "translucent", to describe trasparent paper and envelopes. See similar questions...

For an opaque look three coats should be applied. For a translucent look only one coat needs to be applied. See similar questions...

It is possible for this to happen, if you are in a stable weather system. The surface pressure is probably the least sensitive of those conditions. See similar questions...

A transparent physical material shows objects behind it as unobscured and doesn't reflect light off its surface. Clear glass is a nearly transparent material. Although glass allows most light to pass through unobscured, in reality it also reflects some light. A perfectly transparent material is completely invisible. A translucent physical material shows objects behind it, but those objects are obscured by the translucent material. See similar questions...

All melt and pour soap base is clear. It is the addition of titanium dioxide that makes transparent soap base white or opaque. See similar questions...

opaque object is something that allows no light through it. Concrete, wood, and metal are some examples of opaque materials. Some materials can be opaque to light, yet translucent to other types of electromagnetic waves. For example, wood does not allow visible light to pass through it, but will allow other types of electromagnetic waves, such as microwaves and radio waves. See similar questions...

Translucent vinyl skin tone carries less pigment than our regular light vinyl (and is thereby slightly lighter) and has a translucent "depth" to it that gives it the most life-like look of any vinyl available. This vinyl is less doll-like and more life-like! See similar questions...

A term for databases that must protect some information while revealing other data. In other words, a phrase to capture how the database must exist somewhere between translucency and opacity. See similar questions...

Yes. The adhesive, the nicotine amounts, and the way you use the products are exactly the same. The only difference is the color. See similar questions...

Our coloured glass is completely opaque therefore you don't see any patches on the wall through the glass See similar questions...

Opaque surfaces are those that don't let light through. For instance, steel and wood are opaque surfaces. Glass or clear Lexan® plastic are not opaque surfaces; they are transparent or translucent. We recommend use on opaque surfaces only, because rubber adhesives are changed by their exposure to light. Typically, tape will not come up cleanly when the adhesive has seen light for a time.

No glass door is completely opaque. All glass doors will allow at least an image or outline to be seen through them. Opacity is difficult to accurately measure but the following estimates may be helpful in making your selection. See similar questions...

These bars are commonly known as "hum bars." One cause is that the source and monitor may not share the same electrical ground – instead, they are plugged into separate electric lines grounded on different circuits, or the cable wire itself is not grounded to the same conductor as the unit’s ground. Sometimes battery-powered images sources (camcorders, laptop computers), which share no common electrical ground with the display, introduce the hum bars. See similar questions...

If you want blending to occur after the texture has been applied, then use the OpenGL blending feature. Try this: glEnable (GL_BLEND); glBlendFunc (GL_ONE, GL_ONE); You might want to use the alpha values that result from texture mapping in the blend function. If so, (GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA) is always a good function to start with. However, if you want blending to occur when the primitive is texture mapped (i.e. See similar questions...

No, the amount of clouds covering the sky relates to the cloud cover not the visual opacity. When you report that a cloud is opaque you should be describing thick clouds which do not allow direct light to pass, although light can diffuse through them. Such thick clouds often look gray.
