Class ShaderProgramObject

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

org.web3d.x3d.jsail.Shaders.ShaderProgramObject
All Implemented Interfaces:
X3DNode, X3DUrlObject, ShaderProgram, X3DProgrammableShaderObject
public class ShaderProgramObject
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.
