PDB (Protein Data Bank) is an international database that stores protein structure data. It provides global protein structure information, including atomic coordinates, structural topology, and other related experimental and computational results. The PDB database is jointly managed and maintained by multiple international cooperation organizations.
The main goal of the PDB database is to provide detailed information on protein structures for scientific researchers, biologists, and drug designers. Proteins are crucial molecules in living organisms, and understanding their three-dimensional structure is crucial for understanding their functions and interactions. Through PDB, researchers can access tens of thousands of protein structures and conduct various analyses and comparative studies.
Each entry in the PDB database represents a protein structure, which includes detailed descriptions of the protein's sequence information, topological structure, and chemical composition. These data are obtained through experimental techniques such as X-ray crystallography, nuclear magnetic resonance, etc., or computational simulation methods such as molecular dynamics simulations. The PDB database also provides a series of tools and resources to assist researchers in structural visualization, functional prediction, and drug design.
COLLADA is an XML-based digital asset exchange solution for interactive 3D applications, allowing 3D creation applications to freely exchange digital assets without losing information - enabling a powerful toolchain pipeline combining multiple DCC and 3D processing software packages. Its unique interactive mode provides a comprehensive visual compilation. COLLADA FX supports the creation and encapsulation of shaders using OpenGL ES shading language, enabling first-class 3D creation tools to effectively collaborate in creating OpenGL / OpenGL ES applications and assets.
COLLADA is an open standard, originally used for 3D software data exchange, initiated by SCEA, and now supported by many well-known manufacturers such as Autodesk and XSI. COLLADA can be used not only for exchanging data between modeling tools, but also as a scene description language for small-scale real-time rendering. Because COLLADA DOM has rich content for representing various elements in the scene, from polygonal geometry to cameras, we can use the COLLADA DOM library to read and process scene files. The programming method of COLLADA DOM is similar to COM.
