Detailed Description

Node that defines a tessellation evaluation shader.

This node defines a tessellation evaluation shader.

See SoShaderProgram for general information about using shaders and shader parameters.

See parent class SoShaderObject for details about using the inherited fields.

Notes:

• Shader object nodes cannot be inserted directly in a scene graph.
  They must be added to the shaderObject field of an SoShaderProgram node.

Limitations:

• Tessellation shaders are currently only supported by SoBufferedShape, SoPointSet and SoIndexedPointSet.

• Transparency and fast editing are compatible with shader modified geometry, but most actions use the vertices of the basic shape (the vertices stored in the scene graph). This includes, for example, SoGetBoundingBoxAction, SoGetPrimitiveCountAction and SoRayPickAction.

Member Function Documentation

static SoType SoTessellationEvaluationShader::getClassTypeId

(

)

[static]

Returns the type identifier for this class.

Reimplemented from SoShaderObject.

virtual ShaderType SoTessellationEvaluationShader::getShaderType

(

)

const [inline, virtual]

Returns the shader type.

Implements SoShaderObject.

virtual SoType SoTessellationEvaluationShader::getTypeId

(

)

const [virtual]

Returns the type identifier for this specific instance.

Reimplemented from SoShaderObject.

static SbBool SoTessellationEvaluationShader::isSupported	(	SoShaderObject::SourceType	sourceType,
		SoState *	state = NULL
	)			[static]

Returns true if tessellation evaluation shaders in the specified language are supported by your graphics board.

When using a debug build of Open Inventor, some "no context available" warning messages may be generated. You can ignore them or see SoGLExtension for an example of using SoGLContext to avoid them.
