.SS DESCRIPTION
.PP
The \f[C]RTBufferType\f[] structure defines slots to assign data buffers
to using the [rtcSetGeometryBuffer], [rtcSetSharedGeometryBuffer], and
[rtcSetNewGeometryBuffer] API calls.
.PP
For most geometry types the \f[C]RTC_BUFFER_TYPE_INDEX\f[] slot is used
to assign an index buffer, while the \f[C]RTC_BUFFER_TYPE_VERTEX\f[] is
used to assign the corresponding vertex buffer.
.PP
The \f[C]RTC_BUFFER_TYPE_VERTEX_ATTRIBUTE\f[] slot can get used to
assign arbitrary additional vertex data which can get interpolated using
the [rtcInterpolate] API call.
.PP
The \f[C]RTC_BUFFER_TYPE_NORMAL\f[], \f[C]RTC_BUFFER_TYPE_TANGENT\f[],
and \f[C]RTC_BUFFER_TYPE_NORMAL_DERIVATIVE\f[] are special buffers
required to assign per vertex normals, tangents, and normal derivatives
for some curve types.
.PP
The \f[C]RTC_BUFFER_TYPE_GRID\f[] buffer is used to assign the grid
primitive buffer for grid geometries (see [RTC_GEOMETRY_TYPE_GRID]).
.PP
The \f[C]RTC_BUFFER_TYPE_FACE\f[], \f[C]RTC_BUFFER_TYPE_LEVEL\f[],
\f[C]RTC_BUFFER_TYPE_EDGE_CREASE_INDEX\f[],
\f[C]RTC_BUFFER_TYPE_EDGE_CREASE_WEIGHT\f[],
\f[C]RTC_BUFFER_TYPE_VERTEX_CREASE_INDEX\f[],
\f[C]RTC_BUFFER_TYPE_VERTEX_CREASE_WEIGHT\f[], and
\f[C]RTC_BUFFER_TYPE_HOLE\f[] are special buffers required to create
subdivision meshes (see [RTC_GEOMETRY_TYPE_SUBDIVISION]).
.PP
The \f[C]RTC_BUFFER_TYPE_FLAGS\f[] can get used to add additional flag
per primitive of a geometry, and is currently only used for linear
curves.
