D3DXCreateCylinder

The D3DXCreateCylinder function creates a cylinder of given dimensions.

HRESULT D3DXCreateCylinder(
  LPDIRECT3DDEVICE7 pDevice,
  float baseRadius,
  float topRadius,
  float height,
  DWORD numSlices,
  DWORD numStacks,
  DWORD numTexCoords,
  ID3DXSimpleShape** ppShape
);

Parameters

pDevice

A pointer to the IDirect3DDevice7 interface of the device.

baseRadius

The base-radius of the cylinder. The default value is 1.0f. This parameter should be greater than or equal to 0.0f.

topRadius

The top-radius of the cylinder. The default value is 1.0f. This parameter should be greater than or equal to 0.0f.

height

The height of the cylinder. The default value is 1.0f. This parameter should be greater than or equal to 0.0f.

numSlices

The number of slices about the main axis. The default value is 8. D3DX_DEFAULT is a valid input for this parameter.

numStacks

The number of stacks along the main axis. The default value is 8. D3DX_DEFAULT is a valid input for this parameter.

numTexCoords

The number of texture coordinates desired in the output vertex-buffer. The default value is 1. D3DX_DEFAULT is a valid input for this parameter.

ppShape

The address of a pointer to the output vertex-buffer, an ID3DXSimpleShape interface.

Return Values

If the function succeeds, the return value is S_OK.

If the function fails, the return value may be one of the following values:

Remarks

This function returns a vertex buffer that can be used later for drawing or manipulation by the application.
