GLPRIMITIVERESTARTIN(3G)					  [FIXME: manual]					  GLPRIMITIVERESTARTIN(3G)

NAME

       glPrimitiveRestartIndex - specify the primitive restart index

C SPECIFICATION

       void glPrimitiveRestartIndex(GLuint index);

PARAMETERS

       index
	   Specifies the value to be interpreted as the primitive restart index.

DESCRIPTION

       glPrimitiveRestartIndex specifies a vertex array element that is treated specially when primitive restarting is enabled. This is known as
       the primitive restart index.

       When one of the Draw* commands transfers a set of generic attribute array elements to the GL, if the index within the vertex arrays
       corresponding to that set is equal to the primitive restart index, then the GL does not process those elements as a vertex. Instead, it is
       as if the drawing command ended with the immediately preceding transfer, and another drawing command is immediately started with the same
       parameters, but only transferring the immediately following element through the end of the originally specified elements.

       When either glDrawElementsBaseVertex(), glDrawElementsInstancedBaseVertex() or glMultiDrawElementsBaseVertex() is used, the primitive
       restart comparison occurs before the basevertex offset is added to the array index.

NOTES

       glPrimitiveRestartIndex is available only if the GL version is 3.1 or greater.

GLENABLEVERTEXATTRIB(3G)					  [FIXME: manual]					  GLENABLEVERTEXATTRIB(3G)

NAME

       glEnableVertexAttribArray, glDisableVertexAttribArray - Enable or disable a generic vertex attribute array

C SPECIFICATION

       void glEnableVertexAttribArray(GLuint index);

       void glDisableVertexAttribArray(GLuint index);

PARAMETERS

       index
	   Specifies the index of the generic vertex attribute to be enabled or disabled.

DESCRIPTION

       glEnableVertexAttribArray enables the generic vertex attribute array specified by index.  glDisableVertexAttribArray disables the generic
       vertex attribute array specified by index. By default, all client-side capabilities are disabled, including all generic vertex attribute
       arrays. If enabled, the values in the generic vertex attribute array will be accessed and used for rendering when calls are made to vertex
       array commands such as glDrawArrays(), glDrawElements(), glDrawRangeElements(), glMultiDrawElements(), or glMultiDrawArrays().

ERRORS

       GL_INVALID_VALUE is generated if index is greater than or equal to GL_MAX_VERTEX_ATTRIBS.

ASSOCIATED GETS

       glGet() with argument GL_MAX_VERTEX_ATTRIBS

       glGetVertexAttrib() with arguments index and GL_VERTEX_ATTRIB_ARRAY_ENABLED

       glGetVertexAttribPointerv() with arguments index and GL_VERTEX_ATTRIB_ARRAY_POINTER
