glEnableVertexAttribArray — Enable or disable a generic vertex attribute array
void glEnableVertexAttribArray( | GLuint index); |
void glDisableVertexAttribArray( | GLuint index); |
index Specifies the index of the generic vertex attribute to be enabled or disabled.
glEnableVertexAttribArray enables the generic vertex attribute array specified by index. glDisableVertexAttribArray disables the generic vertex attribute array specified by index. By default, all generic vertex attribute arrays are disabled. 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, glDrawArraysInstanced, glDrawElements, glDrawElementsInstanced, or glDrawRangeElements.
GL_INVALID_VALUE is generated if index is greater than or equal to GL_MAX_VERTEX_ATTRIBS.
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
