2 types of solid object?
A rock. Minerals are included. A Chair.
What is solid area scan conversion?
The problem of finding out pixels that lie within the solid area and find out those that lie outside the solid area that form a part of the object from those that do not is called scan conversion.
What is the difference between solid modelling and surface modelling?
The short easy answer is that with solid modeling, forms are built-up by drawing outlines and protruding them into forms, as well as using other protruded outlines to cut forms. Often these shapes are more geometric overall, and solid modeling is usually used to create the internal details of products. SolidWorks is a solid modeler (but can create surface forms too)Surface modeling develops shapes by stretching a "surface" between 3d curves that you individually create. With it you build forms by creating one small surface at a time, slowly creating the complete shape. The intersections between the surfaces are very controlled so they can be very very smooth or crisp like a crease. Usually the shapes are more freeform and sleeker than an object that was created with solid modeling, but some people are very good and the lines blurrr.. Alias is a surface modeler, but Solidworks can create shapes with surfaces tooolids modeler: Starts with a solid object. You add and subtract other solid objects to it. If you cut into it, you're left with your solid object minus what was cut out--just like in the real-world. It's all very rational.Many solids modelers are "parametric" meaning you can go back and look at the list of commands you've executed since the start of your model (the "construction tree") and change anything (hoping your model doesn't "break.") Very useful!Pro/E and Solidworks are the most popular.Surface modeler: A bunch of infinitely-thin membranes defined by boundary curves. If you want, you can connect one membrane to another, creating a "water-tight" form that looks solid, but if you cut into it, it would be hollow and you'd have to patch the missing cutout piece (intersect tools are typically used to automate this.)Surface modelers generally aren't parametric. There is no construction tree. It's very hard to change something you did and expect the rest of your model to update.Why would you use a surface modeler then? Because it's more freeform, and historically, the tools have allowed you more control over the shapes of those "membranes" than if you were using a solids modeler. And because designers have been attracted to this, the user-interfaces tend to emphasize the freeform more than the solids-modelers, which cater to engineers.Alias and Rhino are the most popular.there are some other differences like parametric history and assemblies as well that make Solidworks a worthwhile software to complement your Alias skills...
Wireless technologies that can transmit through solid objects?
All wireless / radio signals have the capability of passing through solid objects. The problem can best be described as a ratio of the density of the object to the frequency of the signal. A high frequency signal is more likely to bounce off a concrete wall, than, say, a shoji screen. To pass through the most dense objects, you need a signal of the longest wavelength.
What is solid timber made from?
Solid timber is what you'd expect it to be - actual wood. When people say 'solid timber' they want to let you know that the piece of furniture is not made from veneered particle board/mdf etc which may look like solid timber to the untrained eye.
How does a 3 D CAD solid model keep track of the changes that are made to an object?
It keeps track of the changes you make on the browser.
How does particle behavior change as an object changes from a solid?
How does particle behavior change as an object changes from a solid to liquid to gas
What property changes if the size of an object changes?
The property of the object would change "solid, liquid, or gas"
What do you call it when an object changes state from a solid to a gas?
sublimation
A solid that changes to a liquid?
A solid object like an ice cube can be liquid. How you ask? you can just heat it up! to change a liquid object back to a solid, you just freeze it!
What does the change in state involve?
A change of state is a change in the object from a solid to a liquid. Other changes of state are a solid to a gas or from a liquid to a solid.
What object contains chemical energy and then changes into thermal energy?
A match. Solid rocket fuel.
Process name when solid to liquid?
When a liquid changes to a solid the process is known as solidification or, more commonly, freezing.
Is the ability of a solid to resist changes in shape?
Sort of. A solid can have a change in shape, but it has to be forced upon the object, whereas a liquid would have involuntary shape change.
Is a pencil a solid liquid or gas?
A pencil is a solid object.
How will the pressure of an object change if area is doubled?
It won't. The pressure within a hollow object may change if the surface area changes, hence the volume. The total pressure acting on the exterior of a solid object may change if the total surface area changes.
