ID2D1Mesh interface (d2d1.h)
Represents a set of vertices that form a list of triangles.
Inheritance
The ID2D1Mesh interface inherits from ID2D1Resource. ID2D1Mesh also has these types of members:
Methods
The ID2D1Mesh interface has these methods.
ID2D1Mesh::Open Opens the mesh for population. |
Remarks
Creating ID2D1Mesh Objects
To create a mesh, call the ID2D1RenderTarget::CreateMesh method on the render target with which the mesh will be used. A mesh can only be used with the render target that created it and the render target's compatible targets.A mesh is a device-dependent resource: your application should create meshes after it initializes the render target with which the meshes will be used, and recreate the meshes whenever the render target needs recreated. (For more information about resources, see Resources Overview.)
Examples
The following code example shows how to use ID2D1Mesh to represent a set of vertices that form a list of triangles.
ID2D1GeometrySink *pGeometrySink = NULL;
hr = pPathGeometry->Open(&pGeometrySink);
if (SUCCEEDED(hr))
{
hr = pGeometry->Widen(
strokeWidth,
pIStrokeStyle,
pWorldTransform,
pGeometrySink
);
if (SUCCEEDED(hr))
{
hr = pGeometrySink->Close();
if (SUCCEEDED(hr))
{
ID2D1Mesh *pMesh = NULL;
hr = m_pRT->CreateMesh(&pMesh);
if (SUCCEEDED(hr))
{
ID2D1TessellationSink *pSink = NULL;
hr = pMesh->Open(&pSink);
if (SUCCEEDED(hr))
{
hr = pPathGeometry->Tessellate(
NULL, // world transform (already handled in Widen)
pSink
);
if (SUCCEEDED(hr))
{
hr = pSink->Close();
if (SUCCEEDED(hr))
{
SafeReplace(&m_pStrokeMesh, pMesh);
}
}
pSink->Release();
}
pMesh->Release();
}
}
}
pGeometrySink->Release();
}
pPathGeometry->Release();
