Example 28 with AssetInfo

use of com.jme3.asset.AssetInfo in project jmonkeyengine by jMonkeyEngine.

the class Context method createProgramFromSourceFilesWithInclude.

/**
     * Creates a program object from the provided source code and files.
     * The source code is made up from the specified include string first, 
     * then all files specified by the resource array (array of asset paths)
     * are loaded by the provided asset manager and appended to the source code.
     * <p>
     * The typical use case is:
     * <ul>
     *  <li>The include string contains some compiler constants like the grid size </li>
     *  <li>Some common OpenCL files used as libraries (Convention: file names end with {@code .clh}</li>
     *  <li>One main OpenCL file containing the actual kernels (Convention: file name ends with {@code .cl})</li>
     * </ul>
     * 
     * After the files were combined, additional include statements are resolved
     * by {@link #createProgramFromSourceCodeWithDependencies(java.lang.String, com.jme3.asset.AssetManager) }.
     * 
     * @param assetManager the asset manager used to load the files
     * @param include an additional include string
     * @param resources an array of asset paths pointing to OpenCL source files
     * @return the new program objects
     * @throws AssetNotFoundException if a file could not be loaded
