Saved by uncleflo on February 23rd, 2019.

This is going to be a DIY for 99% of the Do It Yourselferss out there. , meaning anyone can build it, this Kit will be assembled with off the shelf products as to keep it as simple as possible , it can also be made with Raw materials which I have done also(will not go into details this time). I built a similar kit about three years ago(posted in a different forum), but recently but recently I found about this site after looking many good instructables for 3D Printers(I will be building a very very frugal basic/Simplistic kit to coat 3D Prints with Silver, Copper and Gold, I will publish it here when I am done)..

Saved by uncleflo on September 8th, 2016.

Over the past two years or so, a very exciting race has been ongoing in the construction world: Who can be the first to develop a commercially viable concrete 3D printer capable of making homes? And the competition has been very tough, as interesting and promising projects quickly began popping up all over the place. Just a few months ago, even Dubai stepped into the race with an ambitious plan, and just this week Italian manufacturers WASP announced the creation of the world’s largest Delta 3D printer with an eye on concrete construction. But today, another team has jumped to the head of the pack, as the innovation-minded Lewis Grand Hotel in the Philippines, owned by entrepreneur Lewis Yakich, has begun work on a massive 3D printed expansion of the hotel. What’s more, they are already planning to follow this up with a series of 3D printed commercial homes. Do we have a winner?

Working in Flash and Actionscript, you will be familiar with the concepts of using the standard display list for drawing and animating content. Away3D versions earlier than 4.0 all relied on this standard display list to render objects to your scene, however since Flash Player 11.0 and Away3D 4.x you can now take advantage of GPU hardware accelerated graphics for rendering performance as commonly seen in games, allowing you to create complex and immersive experiences for the web and using Adobe AIR, on mobile devices as well.

Same Side Technique, Point in triangle test

http://www.blackpawn.com/texts/pointinpoly/

Saved by uncleflo on February 22nd, 2015.

A common way to check if a point is in a triangle is to find the vectors connecting the point to each of the triangle's three vertices and sum the angles between those vectors. If the sum of the angles is 2*pi then the point is inside the triangle, otherwise it is not. It works, but it is very slow. This text explains a faster and much easier method.

There are various ray-tri tests around. I'll describe a few of the most interesting ones because I think that there's no "definitive" ray-tri intersection. Much depends on the type of application you're going to develop. Some methods are faster if most of the tests are positive (hit), some if they are not (early rejection). Some use lots of memory to precalculate as much as possible so they are very fast for scenes with no cache-hit problems (for examples in scenes with not so many, big triangles and spatial subdivision), while others use less memory and no precalc. etc... The precalculation option is often important so I'll talk about it more here. There are two kinds of precalculations that could be useful: per-frame precalculation (something that can be precalculated for the entire scene, for every triangle, and that just needs to be updated if the triangles are animated, if it changes their position in the next frame). The other type is per-ray-bundle precalculation.

Calculating reflected ray

http://paulbourke.net/geometry/reflected/

Saved by uncleflo on February 22nd, 2015.

This short note gives the equation for a reflected ray as used in many computer rendering applications, eg: ray tracing. Given a ray Ri incident at a point on a surface with normal N one wishes to determine the reflected ray from that point. The geometry and nomenclature is given in the following diagram.

When writing a ray tracer, sooner or later you’ll stumble on the problem of reflection and transmission. To visualize mirror-like objects, you need to reflect your viewing rays. To simulate a lens, you need refraction. While most people have heard of the law of reflection and Snell’s law, they often have difficulties with actually calculating the direction vectors of the reflected and refracted rays. In the following pages, exactly this problem will be addressed. As a bonus, some Fresnel equations will be added to the mix, so you can actually calculate how much light is reflected or transmitted (yes, it’s possible). At the end, you’ll have some usable formulas to use in your latest ray tracer.

Intersections of Rays, Planes and Triangles (3D)

http://geomalgorithms.com/a06-_intersect-2.html

Saved by uncleflo on February 22nd, 2015.

The intersection of the most basic geometric primitives was presented in the Algorithm 5 about Intersections of Lines and Planes. We will now extend those algorithms to include 3D triangles which are common elements of 3D surface and polyhedron models. We only consider transversal intersections where the two intersecting objects do not lie in the same plane. Ray and triangle intersection computation is perhaps the most frequent nontrivial operation in computer graphics rendering using ray tracing. Because of its importance, there are several published algorithms for this problem (see: [Badouel, 1990], [Moller & Trumbore, 1997], [O'Rourke, 1998], [Moller & Haines, 1999]). We present an improvement of these algorithms for ray (or segment) and triangle intersection. We also give algorithms for triangle-plane and triangle-triangle intersection.

Snell's law - Wikipedia, the free encyclopedia

http://en.wikipedia.org/wiki/Snell%27s_law#Vector_form

Saved by uncleflo on February 22nd, 2015.

Snell's law (also known as the Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air. In optics, the law is used in ray tracing to compute the angles of incidence or refraction, and in experimental optics to find the refractive index of a material. The law is also satisfied in metamaterials, which allow light to be bent "backward" at a negative angle of refraction with a negative refractive index.

That's an important distinction. Where James Cameron's 1986 film Aliens has been a major influence on video games since its release, and has seen a number of high-profile game adaptations and spinoffs, Ridley Scott's original Alien in 1979 has stood apart. Cameron's big guns and action scenes allowed for an easy power-fantasy hook — despite the intended anti-war message of the film itself — while Scott's frail human prey and solitary alien killer seem less easily adapted.
