OpenGL VAO, VBO equivalent in DirectX11












0















I am working on implementing a directx11 instance of our game engine and I am a newbie in 3d game programming.



I know a little about DirectX11 graphics pipeline and shaders and what vertex buffers, input layout, etc are.



While looking at the one of the APIs the code is something like:



glBindVertexArray(current_vao);

glBindBuffer(GL_ARRAY_BUFFER, current_vbo);

glBufferData(GL_ARRAY_BUFFER, sizeof(Vector3) * Vertices.size(), &Vertices.front(), GL_DYNAMIC_DRAW);

glEnableVertexAttribArray(0);

glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, sizeof(Vector3), reinterpret_cast<void*>(0));

glDisableVertexAttribArray(1);

glDisableVertexAttribArray(2);

glDisableVertexAttribArray(3);

glDisableVertexAttribArray(4);

glDisableVertexAttribArray(5);

glDisableVertexAttribArray(6);

glBindBuffer(GL_ARRAY_BUFFER, 0);


What is this VAO and VBO equivalent in DirectX11 ? What exactly is this code doing ?

          A "VBO" is just a vertex buffer, which in DirectX 11 is a ID3D11Buffer with a bind flag of D3D11_BIND_VERTEX_BUFFER which contains the vertex data.



          There is no direct equivalent to the OpenGL "Vertex Attribute Array". In DirectX 11, you just submit a distinct Draw for each group of like state settings (a.k.a material attribute).




          If you are complete new to DirectX 11, you might consider working through the [DirectX Tool Kit tutorials.
