optix::bufferId< T, Dim > Struct Template Reference

Detailed Description

template<typename T, int Dim>
struct optix::bufferId< T, Dim >

bufferId is a host version of the device side bufferId.

Use bufferId to define types that can be included from both the host and device code. This class provides a container that can be used to transport the buffer id back and forth between host and device code. The bufferId class is useful, because it can take a buffer id obtained from rtBufferGetId and provide accessors similar to the buffer class.

"bindless_type.h" used by both host and device code:

#include <optix_world.h>
struct BufInfo {
  int val;
  rtBufferId<int, 1> data;
};

Host code:

#include "bindless_type.h"
BufInfo input_buffer_info;
input_buffer_info.val = 0;
input_buffer_info.data = rtBufferId<int,1>(inputBuffer0->getId());
context["input_buffer_info"]->setUserData(sizeof(BufInfo), &input_buffer_info);

Device code:

#include "bindless_type.h"
rtBuffer<int,1> result;
rtDeclareVariable(BufInfo, input_buffer_info, ,);

RT_PROGRAM void bindless()
{
  int value = input_buffer_info.data[input_buffer_info.val];
  result[0] = value;
}
