public class SoVertexShader
extends SoShaderObject

Node that defines a vertex shader. This node defines a vertex 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.
• Predefined GLSL variables.
  Open Inventor uses a compatibility profile context for rendering. So legacy GLSL predefined variables, for example gl_ModelViewMatrix, can be used in vertex shaders. However, if you use the GLSL "#version" directive in a shader, you should append the keyword "compatibility", for example: "#version 150 compatibility".
• Shadows.
  To integrate with Open Inventor's shadow casting algorithm, vertex shaders should call the GLSL method OivSetupShadowVertex(). Please see SoShadowGroup for example code.

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 and SoRayPickAction.

File format/default:

VertexShader {

sourceProgram	""
sourceType	FILENAME
isActive	true
parameter	NULL

Method Details

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 vertex 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.
