ComposedShader
Overview
ComposedShader defines a shader where the individual source files are assembled from contained ShaderPart program sections. All access to shading capabilities is defined through a single interface that applies to all parts.
The ComposedShader node belongs to the Shaders component and requires at least level 1, its default container field is shaders. It is available from X3D version 3.0 or higher.

Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.
Hint
SFBool [in] activate
activate forces the shader to activate the contained objects.
Warning
- It is an error to define this transient inputOnly field in an X3D file, instead only use it a destination for ROUTE events.
SFBool [out] isSelected
isSelected indicates this shader instance is selected for use by browser
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFBool [out] isValid
isValid indicates whether current shader objects can be run as a shader program.
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFString [ ] language “” [“Cg”|”GLSL”|”HLSL”|…]
The language field indicates to the X3D player which shading language is used. The language field may be used to optionally determine the language type if no MIME-type information is available.
Hint
- Recognized values include “Cg” “GLSL” “HLSL”.
MFNode [in, out] parts [ ] [ShaderPart]
ComposedShader can contain multiple ShaderPart nodes in the parts field.
Advice
Hints
- ComposedShader contains field declarations and then corresponding IS/connect statements (if any), followed by <ShaderPart
containerField='parts'/>nodes. - Apply default
containerField='shaders'when parent node is Appearance.
Warning
- ComposedShader does not contain CDATA section of plain-text source code. All source programs are contained in child ShaderPart nodes.
