glDrawElementsBaseVertex behaves identically to glDrawElements except that theith element transferred by the corresponding draw call will be taken from element
indices [i] +
basevertex of each enabled array. If the resulting value is larger than the maximum value representable by
type , it is as if the calculation were upconverted to 32-bit unsigned integers (with wrapping on overflow conditions). The operation is undefined if the sum would be negative.
glDrawElementsBaseVertex is only supported if the GL version is 3.2 or greater, or if theARB_draw_elements_base_vertexextension is supported.
GL_INVALID_ENUM is generated if
mode is not an accepted value.
GL_INVALID_VALUE is generated if
count is negative.
GL_INVALID_OPERATION is generated if a geometry shader is active and
mode is incompatible with the input primitive type of the geometry shader in the currently installed program object.
GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer object's data store is currently mapped.
