Is there any example of using shader storage buffers ? #3256

I need to use shader storage buffers to pass structs from c++ to the shader, In OpenGL I used to do it by using GL_SHADER_STORAGE_BUFFER but here I am lost, anyone can help me ? |

In bgfx you just use uniforms or compute buffers. See examples. |

Hello! From what I gather in the examples, compute buffers are just vertex buffers, and I can't seem to find an example passing a vertex buffer as a storage buffer to a vertex shader. Are there any limitations which would prevent storage buffers? Would it be hard to implement, and would a PR with them be accepted? A lot of rather common techniques are impossible without them (vertex pull, visibility buffer etc.). |

You can use a buffer in a vertex shader the same way you use it in a fragment shader. I think the tesselation example matches what you want to do: |

It seems to work. Thanks for the tip! |
