Example 31 with Vector3d

use of maspack.matrix.Vector3d in project artisynth_core by artisynth.

the class MeshBase method setTextureCoords.

/**
 * Explicitly sets the texture coordinates and associated indices for this
 * mesh. The information supplied by <code>coords</code> and
 * <code>indices</code> is copied to internal structures that are
 * subsequently returned by {@link #getTextureCoords} and {@link
 * #getTextureIndices}, respectively.
 * The argument <code>indices</code> specifies an index values into
 * <code>coords</code> for each vertex of each feature, as described for
 * {@link #getNormalIndices()}. If a feature vertex has no texture coordinate
 * value, the index should be specified as <code>-1</code>.
 * If <code>indices</code> is
 * <code>null</code>, then <code>coords</code> should contain one coordinate
 * per vertex and a default index set will be created, appropriate to the
 * mesh subclass.
 *
 * <p>If <code>coords</code> is <code>null</code>, then
 * texture coordinates are explicitly removed and subsequent calls to {@link
 * #getTextureCoords} will return <code>null</code>.
 *
 * @param coords texture coordinates to be set for this mesh
 * @param indices texture indices, or <code>null</code> if the indices are to
 * be automatically generated.
