Class ShaderProgram

java.lang.Object
org.web3d.x3d.jsail.X3DConcreteElement

All Implemented Interfaces:
X3DNode, X3DUrlObject, ShaderProgram, X3DProgrammableShaderObject
public class ShaderProgram
extends X3DConcreteNode
implements ShaderProgram
ShaderProgram can contain field declarations and a CDATA section of plain-text source code.

X3D node tooltip: (X3D version 3.1 or later) [X3DNode,X3DUrlObject,X3DProgrammableShaderObject] ShaderProgram is contained by ProgramShader and provides the source and interface to a self-contained program that occupies one part of the rendering process: either a vertex or fragment shader.
  • Hint: ShaderProgram contains field declarations and then corresponding IS/connect statements (if any).
  • Hint: insert a CDATA block to contain source code embedded within an X3D scene.
  • Hint: a contained CDATA block for source code protects whitespace, line breaks, and literal characters (such as & for ampersand character, < for less-than-sign character, and > for greater-than-sign character) from unintended escape-character modifications by XML parsers.
  • Warning: strict order is required for contained constructs: first field declarations (if any), then IS/connect statements (if any), and finally CDATA source-code block.
  • Hint: apply containerField='watchList' when parent node is LoadSensor.

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.

    • getUSE

      public java.lang.String getUSE()
      Provide String value from inputOutput SFString field named USE.

      Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).
      • Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
      • Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
      • Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.
      Overrides:
      getUSE in class X3DConcreteNode
      Returns:
      value of USE field
      See Also:

    • setUSE

      public final ShaderProgram setUSE​(java.lang.String newValue)
      Accessor method to assign String value to inputOutput SFString field named USE.

      Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).
      • Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
      • Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
      • Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.


      Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.

      Warning: invoking the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.

      Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.
      Specified by:
      setUSE in class X3DConcreteNode
