# glEnableVertexAttribArray

Definition: | include pGUI.e include opengl.e glEnableVertexAttribArray(integer index) -- or -- glDisableVertexAttribArray(integer index)
Description: | enable or disable a generic vertex attribute array index: Specifies the index of the generic vertex attribute to be enabled or disabled.
pwa/p2js: | Supported. (but no disable function as yet)
Notes: | 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 or glDrawElements. glCallList and glCallLists can be entered into display lists. Commands in the display list or lists executed by glCallList or glCallLists are not included in the display list being created, even if the list creation mode is GL_COMPILE_AND_EXECUTE. A display list is just a group of commands and arguments, so errors generated by commands in a display list must be generated when the list is executed. If the list is created in GL_COMPILE mode, errors are not generated until the list is executed.
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
