glsl - 计算着色器中 [[vk::binding(0, 0)]] RWStructuredBuffer 的 GLSL 等价物是什么

Question

我有这个 HLSL，我想用 GLSL 编写等价物。如果有用的话，我正在尝试运行此示例 https://github.com/mcleary/VulkanHpp-Compute-Sample

[[vk::binding(0, 0)]] RWStructuredBuffer<int> InBuffer;
[[vk::binding(1, 0)]] RWStructuredBuffer<int> OutBuffer;

[numthreads(1, 1, 1)]
void Main(uint3 DTid : SV_DispatchThreadID)
{
    OutBuffer[DTid.x] = InBuffer[DTid.x] * InBuffer[DTid.x];
}

Answer 1

等效的 GLSL 应如下所示:

layout(std430, binding = 0) buffer InBuffer {
    int inBuffer[ ];
};

layout(std430, binding = 1) buffer OutBuffer {
    int outBuffer[ ];
};

layout (local_size_x = 1, local_size_y = 1, local_size_z = 1) in;
void main() 
{
    outBuffer[gl_GlobalInvocationID.x] = inBuffer[gl_GlobalInvocationID.x] * inBuffer[gl_GlobalInvocationID.x];
}
