Convert your BMP file to X

Use our free and fast online tool to convert your BMP (Bitmap Image File) image or logo into 3D X (Direct X File) mesh/model files suitable for printing with a 3D printer or for loading into your favorite 3D editing package.

How to Convert your BMP to X Online?

Here are three simple steps to create an X file from a BMP file.

Upload a BMP

Click the "Upload a File" button and select BMP to upload. The maximum file size is 100MB.

Select your Options

Set the dimensions and other options, and click the "Convert to X" button to convert your BMP to X.

Download your X

Click the download link once completed to receive your X file.

BMP to X Conversion Options

Tool

This setting allows you to specify how your BMP image is converted to an X model. The Extrude options will extrude your image into 3D space, while the Standard options will apply a heightmap process to your image.

Detail

The setting can be used to alter the detail of the final X model that is created. The default setting of Medium works well for most Extrude and Heightmap conversions, with the High setting recommended for highly detailed image files.

Add Base

This setting, when given a height of more than zero, will instruct the tool to add a solid 3D base to the final X model. The selected unit of measurement specifies the height of the base.

Remove Background

When this option is enabled, the tool will automatically attempt to make the background of your image transparent.

Specify Color

Manually specify your image background color rather than our tool trying to automatically work it out.

Color

If the tool is unable to identify the background and you know the background color, you can specify it here.

Tolerance

This value can be adjusted to control the background removal tolerance. The higher the value, the more background is removed.

A higher value is useful for creating smoother results if your image is anti-aliased.

Invert Output

When the Invert Output option is checked, the pixel brightness is reversed, i.e., black becomes white and white becomes black, resulting in a 3D model that is reversed.

Units

This setting tells the tool how to size the final 3D model when using the settings below for Width, Height, and Depth settings.

Upload Color Overlay

When using either the Color Extrude or Heightmap options within the Tool menu, you can optionally upload a separate image that can be used to colorize your 3D model.

Color Conversion

This setting instructs the tool on how to interpret the color information of pixels in your image, thereby influencing the creation of the 3D X model. The grayscale option is most commonly used when working with heightmaps, unless you are dealing with specific requirements that necessitate the use of color.

Merge Similar Colors

Use this value to merge similar colors; this is useful if the image is of low quality. A higher number can help reduce the effects of anti-aliasing in the BMP image.

Hole Reduction

With this setting, it is possible to reduce the inclusion of small holes within the 3D model caused by small, darker areas of the source BMP file, which can be useful in situations where the source image has not been optimized for use with the tool.

Transparency Conversion

When your BMP file has a transparent background, this option can instruct the tool on how to treat the transparency, with the transparency converted to either black or white.

Enable Smoothing

When this setting is enabled, the conversion tool will attempt to smooth out any "spikes" within the 3D model that are caused by contrasting pixels in the image being in close proximity to one another.

Z-Axis Mirror

With this option enabled, the tool will mirror the 3D geometry of the generated X model along the Z-axis.

Generate Preview

If you would like the tool to create a 3D preview of your model, then please select this option. It is on by default.

File Format Information for BMP to X

ExtensionBMP
Full NameBitmap Image File
TypeImage
Mime Typeimage/bmp
FormatBinary
ToolsBMP Converters, Create Cookie Cutter, BMP Viewer
Open WithPaint.NET

Description

The BMP file format is a two-dimensional image file format popular on Microsoft Windows operating systems. Data is stored in the BMP file in a raster format, with pixels being represented using various color depths ranging from monochrome 1-bit per pixel (bpp) to full color 24-bits per pixel.

The format can also contain an image alpha channel, which is typically 8 bits per pixel in size and is used to describe image transparency. BMP files can also optionally be compressed using a lossless compression algorithm, meaning smaller files with no loss of image quality.

ExtensionX
Full NameDirect X File
Type3D Model
Mime Typetext/plain

ToolsX Converters, 3D Model Voxelizer, Create X Animation, Text to X, X Viewer

Description

The X 3D file format extension was introduced by Microsoft with the launch of Version 2 of their 3D graphics API, Direct X, back in 2002. The format has evolved over the years; however, in 2014, the X file format was deprecated in favor of newer, more capable formats such as FBX.

The format is a simple text-based file capable of storing 3D mesh information such as vertices, faces, normals, and material information. In addition to basic 3D information, the format can also store animations with the X file format, which is primarily used in the development of games.

X Notes

X files support material and color information. If your uploaded model contains color information, our tool will attempt to save this in the X file at the end of the conversion process. Texture information is not supported at this time.

Image to X Frequently Asked Questions

What does this tool do?

Our tool converts image (bitmap) data into 3D geometry, which is then saved to the common X file format.

What files does it support?

The BMP to X tool can convert the most common image file formats, such as PNG, JPG or any one of our supported image formats. The output is provided in X format, which can be used in most 3D graphics applications.

How does the tool interpret the image pixel data?

3D geometry is created based on the luminosity of each pixel in the source image. For example, using the default tool settings, a black pixel represents a 3D pixel height of 0mm, and a white pixel represents a 3D pixel height of 10mm. Colors in between these will be converted to a 3D pixel in this range.

What does the "Invert Output" option do?

This option reverses the black-to-white range conversion, so with this option set, a black pixel will be rendered as a 3D pixel of 10mm in height, and a white pixel will be rendered as 0mm.

How do I control the Model detail?

The "Detail" option allows you to control the resolution of the created X file. Low detail will generate the model quickly and result in a smaller file. The High option will take longer to generate and can result in very large download files.

What does the "Enable Smoothing" option do?

With this option, the BMP to X converter will attempt to remove or smooth out any spikes in the resulting X 3D model. Spikes are usually caused by highly contrasting adjacent pixels in the source BMP file.

What is the maximum BMP resolution I can upload?

The BMP you upload can be any size; however, our tool will resize your image to a maximum of 800x800 pixels for normal users, and for premium subscription holders, this is increased to a maximum of 1200x1200 pixels.
