What is a .YDL file?
The file extension .YDL represents a PowerFlip YAODL 3D Image File, which is a type of 3D model file. This file format is used specifically by PowerFlip, a software application designed to display and manipulate three-dimensional models. The content of a .YDL file can include various elements such as polygons, quad-meshes (a type of mesh made up of quadrilateral polygons), NURBS (Non-Uniform Rational B-Splines, a mathematical model used in computer graphics for generating and representing curves and surfaces), texture coordinates (which map textures to the 3D surface), and detailed object properties.
Additionally, .YDL files support the specification of colors at different levels, including for individual objects, facets (the flat faces on geometric shapes), and vertices (the corners where two or more edges meet). This allows for detailed and visually rich 3D models.
The primary program that can open and work with .YDL files is SGI PowerFlip. SGI stands for Silicon Graphics, Inc., which is the company that developed the YAODL file format. YAODL stands for "Yet Another Object Description Language," indicating that it is one of many formats designed to describe 3D objects. It's important to note that Silicon Graphics no longer uses the YAODL file format, which might limit the availability of software support and updates for opening and editing .YDL files.
If you need to open a .YDL file, you should use the SGI PowerFlip software, which is specifically designed to handle this type of file. However, due to the discontinuation of support by Silicon Graphics, finding additional programs that can open or convert .YDL files might be challenging.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
