After you have finished filling your execute buffer, it contains the vertices describing your model and a series of instructions about how the vertices should be interpreted. The following sections describe filling an execute buffer:
You can streamline the task of filling execute buffers by taking advantage of the helper macros that ship with the samples in the DirectX SDK. The D3dmacs.h header file in the Misc directory of the samples contains many useful macros that will simplify your work. In particular, the macros PUTD3DINSTRUCTION and VERTEX_DATA are useful for filling execute buffers.
For an example of filling an execute buffer, see Filling the Execute Buffer, in the Direct3D Execute-Buffer Tutorial.
