Sets the rendering quality of a Direct3DRMMeshBuilder3 object.
Syntax
HRESULT SetQuality(
D3DRMRENDERQUALITY quality

Parameters
- quality
- Member of the D3DRMRENDERQUALITY enumerated type that specifies the new rendering quality to use.
Return Value
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible errors, see Direct3D Retained Mode Return Values.
Remarks
An object's quality has three components: shade mode (flat or Gouraud; Phong shading is not yet implemented and will default to Gouraud shading), lighting type (on or off), and fill mode (point, wireframe, or solid).
You can set the quality of a device with IDirect3DRMDevice3::SetQuality. By default it is D3DRMRENDER_FLAT (flat shading, lights on, and solid fill).
You can set the quality of a Direct3DRMMeshBuilder3 object with the SetQuality method. By default, a Direct3DRMMeshBuilder3 object's quality is D3DRMRENDER_GOURAUD (Gouraud shading, lights on, and solid fill).
Tip: Gouraud shading performs better than Phong shading on progressive mesh objects that change their level of detail often or quickly.
Direct3D Retained Mode renders an object at the lowest quality setting based on the device and object's current setting for each individual component. For example, if the object's current quality setting is D3DRMRENDER_GOURAUD, and the device is D3DRMRENDER_FLAT then the object will be rendered with flat shading, solid fill and lights on.
If the object's current quality setting is D3DRMSHADE_GOURAUD|D3DRMLIGHT_OFF|D3DRMFILL_WIREFRAME and the device's quality setting is D3DRMSHADE_FLAT|D3DRMLIGHT_ON|D3DRMFILL_POINT, then the object will be rendered with flat shading, lights off, and point fill mode.
These rules apply to Direct3DRMMeshBuilder3 objects and Direct3DRMProgressiveMesh objects. However, Direct3DRMMesh objects do not follow these rules. Mesh objects ignore the device's quality settings and use the group quality setting (which defaults to D3DRMRENDER_GOURAUD).

Sets the texture coordinates of a specified vertex in a Direct3DRMMeshBuilder3 object.
Syntax
HRESULT SetTextureCoordinates(
DWORD index,
D3DVALUE u,
D3DVALUE v
);
Parameters
- index
- Index of the vertex to be set.
- u and v
- Texture coordinates to assign to the specified mesh vertex.
Return Value
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible errors, see Direct3D Retained Mode Return Values.
See Also
Sets the texture topology of a Direct3DRMMeshBuilder3 object.
Syntax
HRESULT SetTextureTopology(
BOOL cylU,
BOOL cylV
);
Parameters
- cylU and cylV
- Specify TRUE for either or both of these parameters if you want the texture to have a cylindrical topology in the u- and v-dimensions, respectively; otherwise, specify FALSE.
Return Value
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible errors, see Direct3D Retained Mode Return Values.
Remarks
The texture topology flags, cylU and cylV, control the settings of the Direct3D Immediate Mode render states D3DRENDERSTATE_WRAPU and D3DRENDERSTATE_WRAPV. When a wrap flag is TRUE, the rasterizer will cross from one edge of the texture to the opposite edge (toroidal mapping) if it is the shorter path between two texture coordinates. Consider a triangle that has v coordinates ranging from 0.1 and 0.9 along one edge. If WRAPV is FALSE, nearly the full length of the texture will be rendered along the triangle. If WRAPV is TRUE, a sliver from the top of the texture and one from the bottom will be rendered. Additionally, when a wrap flag is TRUE, only the fractional part of a texture coordinate is considered for values greater than 1.0, which means textures will not be tiled across a face when wrap is TRUE.
Controlling the wrapping behavior is necessary for proper interpretation of texture coordinates. If you have a single texture wrapped across many faces, set the cylU and cylV parameters to TRUE. If a model has one texture per face or you want multiple copies of the texture to be tiled across a single face by using texture coordinates greater than 1, set cylU and cylV to FALSE.
Several interfaces expose a SetTextureTopology method. IDirect3DRMMeshBuilder3::SetTextureTopology updates the topology on all component faces, overriding any settings made by IDirect3DRMFace2::SetTextureTopology. By default, IDirect3DRMFrame3::SetTexture reads from the mesh because the default material mode is D3DRMMATERIAL_FROMMESH. If the material mode is not D3DRMMATERIAL_FROMMESH, IDirect3DRMFrame3::SetTexture overrides settings made by IDirect3DRMMeshBuilder3::SetTextureTopology.
