ProgramShader
The ProgramShader node defines a shader that can consist of one or more individually programmable, self contained pieces. Each piece, represented by a ShaderProgram node, shall be a self-contained source that does not rely on any other source file and can manage one part of the programmable pipeline (e.g. vertex or fragment processing).

---|---|---|---|---|---|---|
programs | MFNode | inputOutput | ShaderProgram | Contains zero or more ShaderProgram node instances. Hint: In general, only two ShaderProgram instances will be needed: one each for vertex and fragment processing. Each shader language annex shall refine the required behaviour for processing this field. | ||
logFeature | MFString | inputOutput | state, child, parent, route, eventIn, eventOut | controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything | ||
activate | SFBool | inputOnly | The activate field forces the shader to activate the contained objects. | |||
isSelected | SFBool | outputOnly | The isSelected output field is used to indicate that this shader instance is the one selected for use by the browser. A TRUE value indicates that this instance is in use. | |||
isValid | SFBool | outputOnly | The isValid field is used to indicate whether the current shader objects can be run as a shader program. | |||
metadata | SFNode | inputOutput | MetadataObject | container for payload metadata inside MetadataSet element | ||
language | SFString | initializeOnly | auto | CG; GLSL; HLSL | Indicates to the browser which shading language is used for the source file(s). This field may be used as a hint for the browser if the shading language is not immediately determinable from the source. |
