NAME

rtcSetNewGeometryBuffer - creates and assigns a new data buffer to
  the geometry

SYNOPSIS

#include <embree4/rtcore.h>


void* rtcSetNewGeometryBuffer(
  RTCGeometry geometry,
  enum RTCBufferType type,
  unsigned int slot,
  enum RTCFormat format,
  size_t byteStride,
  size_t itemCount
);

DESCRIPTION

The rtcSetNewGeometryBuffer function creates a new data buffer of specified format ( format argument), byte stride ( byteStride argument), and number of items ( itemCount argument), and assigns it to a geometry buffer slot ( type and slot argument) of the specified geometry ( geometry argument). The buffer data is managed internally and automatically freed when the geometry is destroyed.

The byte stride ( byteStride argument) must be aligned to 4 bytes; otherwise the rtcSetNewGeometryBuffer function will fail.

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.

EXIT STATUS

On failure an error code is set that can be queried using rtcGetDeviceError .
