.SS DESCRIPTION
.PP
The \f[C]rtcSetNewGeometryBuffer\f[] function creates a new data buffer
of specified format (\f[C]format\f[] argument), byte stride
(\f[C]byteStride\f[] argument), and number of items (\f[C]itemCount\f[]
argument), and assigns it to a geometry buffer slot (\f[C]type\f[] and
\f[C]slot\f[] argument) of the specified geometry (\f[C]geometry\f[]
argument).
The buffer data is managed internally and automatically freed when the
geometry is destroyed.
.PP
The byte stride (\f[C]byteStride\f[] argument) must be aligned to 4
bytes; otherwise the \f[C]rtcSetNewGeometryBuffer\f[] function will
fail.
.PP
The allocated buffer will be automatically over\-allocated slightly when
used as a vertex buffer, where a requirement is that each buffer element
should be readable using 16\-byte SSE load instructions.
.SS EXIT STATUS
.PP
On failure an error code is set that can be queried using
\f[C]rtcGetDeviceError\f[].
