what space so i need to convert the ray to ? , i am not using picking btw, i am placing a ray at a position of an object and and the direction is 0.0f,-1.0f,0.0f
this is the intersect function
void CTiny::IntersetFloor(IDirect3DDevice9* pd3dDevice,ID3DXMesh* mesh,D3DXMATRIX Param)
{
pd3dDevice->GetTransform(D3DTS_WORLD, &matWorld);
pd3dDevice->GetTransform(D3DTS_VIEW, &matView);
origin = D3DXVECTOR3(m_vPos.x, m_vPos.y, m_vPos.z);
direction = D3DXVECTOR3(0.0f, 1.0f, 0.0f);
// find the inverse matrix
D3DXMatrixInverse(&matInverse, NULL, &(Param* matView)); //(matWorld * matView));
// convert origin and direction into model space
D3DXVec3TransformCoord(&origin, &origin, &matInverse);
D3DXVec3TransformNormal(&direction, &direction, &matInverse);
D3DXVec3Normalize(&direction, &direction);
// detect picking
BOOL hit;
D3DXIntersect(mesh, &origin, &direction, &hit, NULL, NULL, NULL, NULL, NULL, NULL);
if(hit)
{
pd3dDevice->SetRenderState(D3DRS_LIGHTING, FALSE);
pd3dDevice->SetRenderState(D3DRS_FILLMODE, D3DFILL_WIREFRAME);
//MessageBox(NULL,L"Hit",L"",0);
}
else
{
pd3dDevice->SetRenderState(D3DRS_LIGHTING, TRUE);
pd3dDevice->SetRenderState(D3DRS_FILLMODE, D3DFILL_SOLID);
}
}
the call
// draw each tiny
vector <CTiny*>::iterator itCur, itEnd = g_v_pCharacters.end();
for( itCur = g_v_pCharacters.begin(); itCur != itEnd; ++ itCur )
{
// set the time to update the hierarchy
( *itCur )->AdvanceTime( fElapsedTime, &vEye );
// draw the mesh
( *itCur )->Draw();
( *itCur )->IntersetFloor(pd3dDevice,g_pMeshFloor,g_mxFloor); //last param is the floor matrix rot and translate...
}
