rtcSetNewGeometryBuffer(3)

  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.
