Function Documentation

PwModCreateCon()

PWGM_HCONNECTOR PwModCreateCon	(	PWGM_HGRIDMODEL	model,
		PWP_UINT	size
	)

Creates a connector in a model.

Parameters

model	The grid model handle.
size	Specifies the number of points in the connector.

Returns

A connector handle.

PwModCreateStrBlock(), PwModCreateStrDomain()

Sample usage:

These snippets are from the GrdpTEST sample plugin included with the Plugin SDK.

The doCreateCon() function creates a connector and loads its vertices:

static void
doCreateCon(const GRDP_RTITEM &rti)
{
    // Create a 5 point connector
    PWGM_HCONNECTOR hCon = PwModCreateCon(rti.model, 5);
    PWGM_HVERTEXLIST hVL = PwConGetVertexList(hCon);
    if (PWGM_HVERTEXLIST_ISVALID(hVL)) {
        PwConSetName(hCon, "MyConnector-1");
        PwVlstSetXYZ(hVL, 0, 0.0, 0.0, 1.5);
        PwVlstSetXYZ(hVL, 1, 1.0, 0.0, 1.5);
        PwVlstSetXYZ(hVL, 2, 1.0, 1.0, 1.5);
        PwVlstSetXYZ(hVL, 3, 0.0, 1.0, 1.5);
        PwVlstSetXYZ(hVL, 4, 0.0, 1.0, 2.5);
    }
}

PwModCreateStrBlock()

PWGM_HBLOCK PwModCreateStrBlock	(	PWGM_HGRIDMODEL	model,
		const PWGM_STR_SIZE	blkSize
	)

Creates a structured block in a model.

Parameters

model	The grid model handle.
blkSize	Specifies the ijk size of the structured block. The number of points is computed as (i * j * k).

Returns

A block handle.

Sample usage:

These snippets are from the GrdpTEST sample plugin included with the Plugin SDK.

The doCreateStrBlk() function creates a structured block and loads its vertices:

static void
doCreateStrBlk(const GRDP_RTITEM &rti)
{
    const PWGM_STR_SIZE szBlk = { 2, 3, 3 }; // i j k
    PWGM_HBLOCK hSBlk = PwModCreateStrBlock(rti.model, szBlk);
    PWGM_HVERTEXLIST hVL = PwBlkGetVertexList(hSBlk);
    if (PWGM_HVERTEXLIST_ISVALID(hVL)) {
        PwBlkSetName(hSBlk, "MyStrBlock-1");
        // k=0 vertices
        PwVlstSetXYZ3(hVL, n3(0, 0, 0), 0.0, 0.0, 0.0);
        PwVlstSetXYZ3(hVL, n3(0, 1, 0), 0.0, 1.0, 0.0);
        PwVlstSetXYZ3(hVL, n3(0, 2, 0), 0.0, 2.0, 0.0);
        PwVlstSetXYZ3(hVL, n3(1, 0, 0), 1.0, 0.0, 0.0);
        PwVlstSetXYZ3(hVL, n3(1, 1, 0), 1.0, 1.0, 0.0);
        PwVlstSetXYZ3(hVL, n3(1, 2, 0), 1.0, 2.0, 0.0);
        // k=1 vertices
        PwVlstSetXYZ3(hVL, n3(0, 0, 1), 0.0, 0.0, 0.5);
        PwVlstSetXYZ3(hVL, n3(0, 1, 1), 0.0, 1.0, 0.5);
        PwVlstSetXYZ3(hVL, n3(0, 2, 1), 0.0, 2.0, 0.5);
        PwVlstSetXYZ3(hVL, n3(1, 0, 1), 1.0, 0.0, 0.5);
        PwVlstSetXYZ3(hVL, n3(1, 1, 1), 1.0, 1.0, 0.5);
        PwVlstSetXYZ3(hVL, n3(1, 2, 1), 1.0, 2.0, 0.5);
        // k=2 vertices

        PwVlstSetXYZ3(hVL, n3(1, 1, 2), 1.0, 1.0, 1.0);
        PwVlstSetXYZ3(hVL, n3(1, 2, 2), 1.0, 2.0, 1.0);

Sample usage:

These snippets are from the GrdpTEST sample plugin included with the Plugin SDK.

The doCreateStrDom() function creates a structured domain and loads its vertices:

static void
doCreateStrDom(const GRDP_RTITEM &rti)
{
    const PWGM_STR_SIZE szBlk = { 2, 3 }; // i j (k ignored)
    PWGM_HDOMAIN hSDom = PwModCreateStrDomain(rti.model, szBlk);
