SafeDisposable
public class SoGeometryShader extends SoShaderObject
Node that defines a geometry shader. This node defines a geometry 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 anSoShaderProgram
node. - Since Open Inventor 10.0, when writing geometry shaders, the input and output primitive types must be specified in the shader code. See
https://developer.openinventor.com/index.php/general-documentation/how-to-write-shaders-with-oiv-10/#geomshader for more information.
Limitations:
- 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
. - The input primitive type must match the primitive type used with the rendering command that renders with this shader program. Valid inputs are points, lines and triangles so shapes like
SoCube
,SoIndexedFaceSet
defines with quads or polygons,SoQuadMesh
are not compatible withSoGeometryShader
.

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)
Indicates if geometry 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.
