GLPRIMITIVERESTARTIN(3G) OpenGL 3.3 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. SEE ALSO

GLENABLEVERTEXATTRIB(3G) OpenGL 3.3 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 SEE ALSO
