glEnableVertexAttribArray, glDisableVertexAttribArray: Enable or disable a generic vertex attribute array
Function Definition
void glEnableVertexAttribArray(GLuint index); void glDisableVertexAttribArray(GLuint index);
- 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.
GL_INVALID_OPERATION is generated if no vertex array object is bound.
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
