GPGPU technology has stimulated the appearance of several renderings on the GPU in the market, including iRay, V-ray RT, Octane, and Arion. But open-source community made available at least two free renders on the GPU: SmallLuxGPU and Cycles Render. I want to share my impressions about the second one.
Cycles Render is unbiased render with the ability to render on the GPU (CUDA and OpenCL for ATI). It lies in a box with the Blender that runs on Windows, Linux, and OSX.
Cycles Render, this is a car with the procedural texture, FullHD was prepared in 2 minutes using GTX580.
These days it is almost impossible to find a clear and understandable description. Honestly, this is my first article (hopefully not the last one). I will give you an example of top 5 3D printed models.
The main part of the list is taken from the official blog post of Stratasys Ltd, (in the past it was Objet. Two companies merged into one), but this is not the point. The purpose of my post to show the capabilities of three-dimensional printing.
The laws of physics have helped to create an outfit for a new Disney star.
Quite often we have seen some discrepancy between the movements of drawn characters and the movements of a real person, because there are failures to comply with the laws of physics, but it is all in the past. To replace outdated technologies come new ones that help to create advanced characters with perfected movements. Even characters’ clothes now look real, and it is subjected to the laws of physics, considering the friction and elasticity.
In today's world three-dimensional technologies have become very popular. 3D comes in the life of ordinary man rapidly and diversely, starting from 3D TVs, 3D scanners and even printers. Although the last two types of devices are available so far only to specialists. However, the technologies are not standing still. There have already become available three-dimensional printers that cost about $ 2,000 dollars. That fact is bringing closer the day when these devices will become available for every student, engineer or designer. Concerning methods to get the 3D model of a real physical object, then here is not everything that clear. It requires an expensive laser scanner, or you can try your luck with a web camera and the special software. Today anyone could have all these things.
However, there is a very simple way to scan the object into the 3D model using a conventional digital camera. How to do all that will be discussed further.
Now, it is the Year of Dragon. Traditionally, it is an important and successful year, the year of battles and victories. Previous 2011 passed as the typical one. During past year were done a lot of good things, such as the new patents, variety of products and continuous development of technology. However, this article will be about something else. The story will be about a girl by a name Sintel and the dragon from the short film Sintel, released by Blender Foundation more than a year ago. This film gave a huge drive to the development of the free open source 3D content creation suite Blender for the entire year 2011. Of course, this article should have been posted in the past, but it is better late than never.
A devil is hidden in the details. In computer science there is no project that could have gotten without the transition to a simplified character that does not correspond to the real world. Here are examples: illumination, hair, tissue and many other things. Therefore, there will be a lot of clickable pictures (caution, the traffic!). All models and scenes from the film are licensed under CC-BY 3.0 and are available as archives of svn project.
So, let us get started!
Many IT people watch an anime. Majority people have seen it at least once. How is it created?
It begins with an idea. Sometimes, a brainstorm is done in order to choose just one, but better idea. Occasionally, the management makes a decision. Anyway, this is the first and most tedious step. After the idea has been selected, a team is put together, which will deal with its implementation, as well sponsors are needed. Anime is actually a pretty expensive thing, because the showing cost of 52 episodes late at night is close to 50 million yen (it is about 500 000 US dollars) for 5-7 TV channels, and the anime Fullmetal Alchemist to show at 6 pm will cost in 10 times more expensive!
The next couple steps are not necessary in the case if the anime will be drawn as the manga-based. A large majority of theses Japanese cartoons are on the market. By the way, if manga was successful or not, we can find out in advance whether anime will be successful. It is worth noting that sometimes it could be vice versa - manga is drawn by anime. For example, thus it was with FLCL.
This article will tell you about the Isosurface rendering.
So, what is Isosurface – according to Wikipedia is a three-dimensional analog of an isoline. It is a surface that represents points of a constant value (e.g. pressure, temperature, velocity, density) within a volume of space; in other words, it is a level set of a continuous function whose domain is 3D-space. Let us take a look at the pictures:
These images show the surfaces with a different value “constant value” - the density. On the first image a value is less than on the second.
