glDrawElementsBaseVertex — render primitives from array data with a per-element offset
Specifies what kind of primitives to render.
GL_TRIANGLES are accepted.
Specifies the number of elements to be rendered.
Specifies the type of the values in indices. Must be one of
Specifies a pointer to the location where the indices are stored.
Specifies a constant that should be added to each element of
when chosing elements from the enabled vertex arrays.
glDrawElementsBaseVertex behaves identically to
glDrawElements except that the ith element
transferred by the corresponding draw call will be taken from element
of each enabled array. If the resulting value is larger than the maximum value representable by
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.
glDrawElementsBaseVertexis only supported if the GL version is 3.2 or greater, or if the
ARB_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
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.
