Avatar UV Texture Templates for use in Linden Labs Second Life Linden Lab has provided us with Templates and Models to help us make Skins and Clothing for our Avatars. However, Ive found that the templates leave several things to be desired. They arent set up for accurate matching across the UV Seams, and its difficult to find your place when working with them. The original idea to subdivide the Avatar models came from Chip Midnights excellent templates.

I took the models, subdivided them in Light. Wave, and used the tools there to make Vector UV Maps for all the parts. Sony Bdx-S600u Mac Driver. Then I added some things in Adobe Illustrator to get maps that are much easier for me to work with. I think you might find them easier, too. These have the non subdivided polygons in different colors for each map, so you can tell at a glance which portion of the map you are working on. They also have large Matching Outlines, in different colors, so you can easily tell which parts of the map meet the others on the Avatar. Ive added colored horizontal stripes and black vertical stripes to make it simpler to tell which row of polys are which. In addition, Ive put colored Match Lines on the arms and shoulders, since those are the areas that are frequently hardest to match, so you can see exactly which polygon edges meet up across the front and back of the maps. Most importantly, I think, Ive kept the original maps as Vector Smart Objects, which you can use if you have Adobe CS2 or better. Vector Smart objects are real live vectors, so they remain sharp at any resolution. Which means that, if you have CS2 or better, you can resize the maps to 2. You will need to resize to 5.

STL File Format for 3. D Printing Simply Explained. What is an STL file What is it good for How does it work We simply explain the STL file format for 3. D printing in depth. Heres a primer on what they are and how they work, the advantages and disadvantages of their use, plus alternative file formats to consider. In this article, were talking about the 3. D printing file format, not about the Standard Template Library in C. STL File Format for 3. D Printing Simply Explained. What is an STL File What does the file extension.

Color in STL File Format. STL file resources. What is an STL File In a nutshell, an STL file stores information about 3. D models. This format describes only the surface geometry of a three dimensional object without any representation of color, texture or other common model attributes. These files are usually generated by a computer aided design CAD program, as an end product of the 3. D modeling process. STL is the file extension of the STL file format. The STL file format is the most commonly used file format for 3. D printing. When used in conjunction with a 3. D slicer, it allows a computer to communicate with 3. D printer hardware. Since its humble beginnings, the STL file format has been adopted and supported by many other CAD software packages, and today is widely used for rapid prototyping, 3. Out Of The Shadow Rogue Wave Rar. D printing, and computer aided manufacturing. Hobbyists and professionals use it alike. What does the file extension. STL stand for The true meaning of the file extension. STL has been lost to the mists of time. Its widely believed to be an abbreviation of the word STereo. Lithography, though sometimes it is also referred to as Standard Triangle Language or Standard Tessellation Language. How does the STL file format store a 3. Download Two Player Airplane Fighting Games Software on this page. D model The main purpose of the STL file format is to encode the surface geometry of a 3. D object. It encodes this information using a simple concept called tessellation. Tessellation. Tessellation is the process of tiling a surface with one or more geometric shapes such that there are no overlaps or gaps. If you have ever seen a tiled floor or wall, that is a good real life example of tessellation. Tessellation can involve simple geometric shapes or very complicated and imaginative shapes. Here are some examples of artistic tessellations due to the famous painter M. C. Escher. In fact, if you want to see more examples of amazing tessellations, we recommend that you check out his paintings. The invention of the STL file format exploiting tessellation to encode surface geometry. Back in 1. 98. 7, Chuck Hall had just invented the first stereolithographic 3. D printer, and The Albert Consulting Group for 3. D Systems were trying to figure out a way to transfer information about 3. D CAD models to the 3. D printer. They realized that they could use tessellations of the 3. D models surface to encode this information The basic idea was to tessellate the 2 dimensional outer surface of 3. D models using tiny triangles also called facets and store information about the facets in a file. Lets look at a few examples to understand how this works. For example, if you have a simple 3. D cube, this can be covered by 1. As you can see, there are two triangles per face. Since the cube has six faces, it adds up to 1. If you have a 3. D model of a sphere, then it can be covered by many small triangles, also shown in the same image. Here is another example of a very complicated 3. D shape which has been tessellated with triangles. The Albert Consulting Group for 3. D Systems realized that if they could store the information about these tiny triangles in a file, then this file could completely describe the surface of an arbitrary 3. D model. This formed the basic idea behind the STL file format How does an STL file store information about facets The STL file format provides two different ways of storing information about the triangular facets that tile the object surface. These are called the ASCII encoding and the binary encoding. In both formats, the following information of each triangle is stored The coordinates of the vertices. The components of the unit normal vector to the triangle. The normal vector should point outwards with respect to the 3. D model. 4. 1 The ASCII STL file format. The ASCII STL file starts with the mandatory line where is the name of the 3. D model. Name can be left blank, but there must be a space after the word solid in that case. The file continues with information about the covering triangles. Information about the vertices and the normal vector is represented as follows facet normal nx ny nz. Here, n is the normal to the triangle and v. Co ordinate values are represented as a floating point number with sign mantissa e sign exponent format, e. The file ends with the mandatory line 4. The binary STL file format. If the tessellation involves many small triangles, the ASCII STL file can become huge. This is why a more compact binary version exists. The binary STL file starts with a 8. This is generally ignored by most STL file readers, with some notable exceptions that we will talk about later. After the header, the total number of triangles is indicated using a 4 byte unsigned integer. UINT88. 0 Header. UINT3. 2 Number of triangles. The information about the triangles follow subsequently. The file simply ends after the last triangle. Each triangle is represented by twelve 3. Just like the ASCII STL file, 3 numbers are for the 3. D Cartesian co ordinates of the normal to the triangle. The remaining 9 numbers are for the coordinates of the vertices three each. Heres how this looks like foreach triangle. REAL3. 23 Normal vector. REAL3. 23 Vertex 1. REAL3. 23 Vertex 2. REAL3. 23 Vertex 3. UINT1. 6 Attribute byte count. Note that after each triangle, there is a 2 byte sequence called the attribute byte count. In most cases, this is set to zero and acts a spacer between two triangles. But some software also use these 2 bytes to encode additional information about the triangle. We will see such an example later, where these bytes will be used to store color information. Special rules for the STL format. The STL specification has some special rules for tessellation and for storing information. The vertex rule. The vertex rule states that each triangle must share two vertices with its neighboring triangles. This rule is to be respected when tessellating the surface of the 3. D object. Heres an example of a valid and invalid tessellation, according to this rule. The figure on the left violates this rule and is an invalid tessellation, while the figure on the right is conformant and a valid tessellation. The orientation rule. The orientation rule says that the orientation of the facet i. D object and which way is out must be specified in two ways. First, the direction of the normal should point outwards. Second, the vertices are listed in counterclockwise order when looking at the object from the outside right hand rule. This redundancy exists for a reason. It helps ensure consistency of the data and spot corrupt data.
