DirectX11 IASetVertexBuffers "ID3D11Buffer*" is incompatible with
The error message you provided, "ID3D11Buffer* is incompatible with ID3D11Buffer**," suggests that there is a type mismatch or incorrect usage of pointers when calling the IASetVertexBuffers
function in DirectX 11.
The IASetVertexBuffers
function in DirectX 11 expects an array of vertex buffer interfaces (ID3D11Buffer*
) as one of its parameters. Each element in the array represents a vertex buffer that you want to bind to the input-assembler stage.
Here's the correct usage of IASetVertexBuffers
:
cpp// Define an array of vertex buffers
ID3D11Buffer* vertexBuffers[] = { pBuffer1, pBuffer2, pBuffer3, ... };
// Bind the vertex buffers to the input-assembler stage
UINT stride = sizeof(VertexType);
UINT offset = 0;
deviceContext->IASetVertexBuffers(0, numBuffers, vertexBuffers, &stride, &offset);
Ensure that the vertexBuffers
array contains valid ID3D11Buffer*
pointers to the vertex buffers you want to bind. The numBuffers
parameter specifies the number of vertex buffers in the array.
If you're encountering the "incompatible" error, double-check the declaration and usage of your ID3D11Buffer*
variables. Ensure that you're passing the correct pointers and not mistakenly using double pointers (ID3D11Buffer**
) or any incompatible data types.
If you can provide additional code snippets or more context about your implementation, I can assist you further in identifying and resolving the issue.
