ComposedShader
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 its container field is shaders. It is available since X3D version 3.0 or later.
Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.
SFBool [in] activate
Activate forces the shader to activate the contained objects.
SFBool [out] isSelected
IsSelected indicates this shader instance is selected for use by browser
SFBool [out] isValid
IsValid indicates whether current shader objects can be run as a shader program.
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" "FX"
