NAME

       glVertexAttribDivisor - modify the rate at which generic vertex attributes advance during instanced rendering

C SPECIFICATION

       void glVertexAttribDivisor(GLuint index, GLuint divisor);

PARAMETERS

       index
	   Specify the index of the generic vertex attribute.

       divisor
	   Specify the number of instances that will pass between updates of the generic attribute at slot index.

DESCRIPTION

       glVertexAttribDivisor modifies the rate at which generic vertex attributes advance when rendering multiple instances of primitives in a
       single draw call. If divisor is zero, the attribute at slot index advances once per vertex. If divisor is non-zero, the attribute advances
       once per divisor instances of the set(s) of vertices being rendered. An attribute is referred to as instanced if its
       GL_VERTEX_ATTRIB_ARRAY_DIVISOR value is non-zero.

       index must be less than the value of GL_MAX_VERTEX_ATTRIBUTES.

NOTES

       glVertexAttribDivisor is available only if the GL version is 3.3 or higher.

ERRORS

       GL_INVALID_VALUE is generated if index is greater than or equal to the value of GL_MAX_VERTEX_ATTRIBUTES.

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
