Color obj file download

If you include metallic materials, embedded electronic components can be part of a printed object. OBJ files support this level of detail, so you can use them to design micron-level objects.

Multi-color printers are becoming popular. These printers can create more realistic objects than single color printers like organ models that a surgeon studies before an operation or artists or manufacturers can use them to design phone cases with custom images, for example.

Since OBJ files can create multiple colors via a supporting MTL file , you can use them to design objects for a multi-color 3D printer.

There are more applications available, but one of the options should work for most people. OBJ files have some advantages over other 3D file formats. These tips will help you decide if the format is the right choice:.

Like all file formats, OBJ files do have some limitations, and it may be better to use a different format. Those scenarios include:. An OBJ file consists of several statement types that, when combined, define a 3D object. The statements describe shapes and locate them in relation to each other. Comment statements start with. The language ignores anything after until the next line, allowing developers to leave notes for themselves or others who may be viewing their code.

A vertex is a point where the corners of a face or polygon meet. Vertex statements start with v and contain the following:. A UV defines how a 3D model is mapped onto a 2D surface such as computer display and determines how to apply textures to the 3D object; they are sometimes called texture vertexes. UV statements start with vt and contain the following:.

A vertex normal defines shading and brightness by indicating the direction of a light source. Vertex normal statements start with vn and contain the following:.

Parameter space vertex statements start with vp and contain the following:. Here is a sample of a portion of an. Free-form curve or surface types include basis matrix, Bezier curves, B-spline, Cardinal, and Taylor.

The definitions contain the following:. Here is a sample of a portion of an cubic Bezier surface made with a basis matrix from the University of Utah School of Computing:.

Other elements that you can include are points p , lines l , faces f , curves and 2d curves curv and curv2D respectively , and surfaces surf.

You can connect various elements with grouping statements. Groups use the following indicators, followed by names to define each group:. OBJ files can reference vertices, normal, etc. OBJ files have three different ways to encode the surface geometry of an object. Each method has its strengths and is good to use in various situations.

If he just takes the OBJ exporter to make his own, I really fail to see how that's "wrong". The wrong way is not doing any work because it is always the wrong way to someone. Once you start changing the exporter to do extra stuff , it is no longer an OBJ exporter, it's something else.

From there, it could turn into just about any multi-headed beast. Still, good answer, I'd never heard of PLY. It's much more complex than OBJ and it allows more flexibility than one would reasonably need to use for a static model.

Clever way to hopefully not break compatibility with existing OBJ parsers. Are you aware of any real documentation for this from any of the folks supporting it? How about any open source code that implements it? Is there actually a written standard for obj which is widely accepted? Material statements look like this: newmtl redMtl Kd 1.

Probably by putting usemtl statements before each v statement. But maybe this didn't catch on in third-party apps? It is a bit awkward. Benny Jobigan Benny Jobigan 1 1 bronze badge. It doesn't seem to work as blender throws away the 3rd coordinate.
