Misc Flags = 0; Vertex Data.p Sys Mem = Vertices; HRESULT result = this- I am currently using ID3D10Buffer:: Map() to update my vertices which works fine right now. I read Microsoft's page on it and it's not directed towards vertex buffers.Position = D3DXVECTOR3(-2.0f, 1.0f, 0.0f); Vertices[8]. Color = D3DXVECTOR4(0.0f, 1.0f, 0.0f, 1.0f); D3D10_BUFFER_DESC vbd; vbd. Byte Width = sizeof(Vertex_Pos Col) * Vertice Count; vbd. This issue is that my application may require large amounts of vertex updates in the future but not every vertex in every mesh/buffer(one day, a buffer will hold multiple meshes). I was hoping that someone can explain to me how to implement it in regards to vertex buffers and/or link me to some helpful resources that do the same. Which is better to use depends on resource properties and update frequency (read Nvidia's "canonical" paper). Here is a case for simple 1D buffer, such as vertex buffer.

Position = D3DXVECTOR3(1.0f, 2.0f, 0.0f); Vertices[2]. Color = D3DXVECTOR4(0.0f, 1.0f, 0.0f, 1.0f); Vertices[3].* All trademarks and logos are the properties of their respective holders.* Due to standard PC architecture, a certain amount of memory is reserved for system usage and therefore the actual memory size is less than the stated amount.As far as I have looked everywhere says to use ID3D10Device:: Copy Subresource Region(). // Source array/vector (src Data): [xxxx DATADATADATADATADATAxxxxxxxxxxx] // ^ ^ // src Begin (src Begin bytes To Copy) // // Destination buffer (p Buffer): [xx DATADATADATADATADATAxxxxxxxxxxxxx] // ^ ^ // destination Begin (destination Begin bytes To Copy) D3D11_BOX box; = destination Begin; box.right = destination Begin bytes To Copy; = 0; box.bottom = 1; box.front = 0; = 1; Device- method is suited for copying data between two resources (such as buffers or textures).Simplifying, you can think of it as of copying chunks of data inside videocard's memory (but that's not always true).
