SafeDisposable
public class SoTessellationEvaluationShader extends SoShaderObject
Node that defines a tessellation evaluation shader. This node defines a tessellation evaluation shader.
SeeSoShaderProgram
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 anSoShaderProgram
node.
Limitations:
- Tessellation shaders are currently only supported by
SoBufferedShape
,SoPointSet
andSoIndexedPointSet
. - 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
andSoRayPickAction
.

Method Detail

isSupported
public static boolean isSupported(SoShaderObject.SourceTypes sourceType)
Calls isSupported(sourceType, (com.openinventor.inventor.misc.SoState)null).
-
isSupported
public static boolean isSupported(SoShaderObject.SourceTypes sourceType, SoState state)
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 seeSoGLExtension
for an example of usingSoGLContext
to avoid them.
