rtcUpdateGeometryBuffer - marks a buffer view bound to the geometry as modified
#include <embree3/rtcore.h> void rtcUpdateGeometryBuffer( RTCGeometry geometry, enum RTCBufferType type, unsigned int slot );
rtcUpdateGeometryBuffer function marks the buffer view bound to the specified buffer type and slot (
slot argument) of a geometry (
geometry argument) as modified.
If a data buffer is changed by the application, the
rtcUpdateGeometryBuffer call must be invoked for that buffer. Each buffer view assigned to a buffer slot is initially marked as modified, thus this function needs to be called only when doing buffer modifications after the first
On failure an error code is set that can be queried using
