    Picking Intersection Vertices

    Finally figured it out. Was mistaking RayOrgin for point in triangle clicked in its local space, but realized that no matter where I clicked the same spot would be selected. So I used the BaryCentric coordinates u,v to find highest influence, which results in the vertice that is the closest on the face to be selected. **This is from Frank D Luna directX book modified for point selection.   void PickingApp::pick(int sx, int sy) { D3DXMATRIX P = GetCamera().proj(); // Compute picking ray in view space. float vx = (+2.0f*sx/mClientWidth - 1.0f)/P(0,0); float vy = (-2.0f*sy/mClientHeight + 1.0f)/P(1,1); D3DXVECTOR3 rayOrigin(0.0f, 0.0f, 0.0f); D3DXVECTOR3 rayDir(vx, vy, 1.0f); // Tranform to world space. D3DXMATRIX V = GetCamera().view(); D3DXMATRIX inverseV; D3DXMatrixInverse(&inverseV, 0, &V); D3DXVec3TransformCoord(&rayOrigin, &rayOrigin, &inverseV); D3DXVec3TransformNormal(&rayDir, &rayDir, &inverseV); // Transform to the mesh's local space. D3DXMATRIX inverseW; D3DXMatrixInverse(&inverseW, 0, &mBaseWorld); D3DXVec3TransformCoord(&rayOrigin, &rayOrigin, &inverseW); D3DXVec3TransformNormal(&rayDir, &rayDir, &inverseW); ID3DX10Mesh* d3dxmesh = mBaseMesh.d3dxMesh(); UINT hitCount; float u,v,t; ID3D10Blob* allHits; d3dxmesh->Intersect(&rayOrigin, &rayDir, &hitCount, &mPickedTriangle, &u, &v, &t, &allHits); float v0 = 1 - u - v; float v1 = u; float v2 = v; if(v0 > v1 && v0 > v2) inf = mPickedTriangle * 3; if(v1 > v0 && v1 > v2) inf = mPickedTriangle * 3 + 1; if(v2 > v0 && v2 > v1) inf = mPickedTriangle * 3 + 2; ReleaseCOM(allHits); } drawScene(){ ..... ...... if( mPickedTriangle != -1 )     {         ID3DX10Mesh* d3dxmesh = mBaseMesh.d3dxMesh();         ID3DX10MeshBuffer* vb = 0;         ID3DX10MeshBuffer* ib = 0;         HR(d3dxmesh->GetVertexBuffer(0, &vb));         HR(d3dxmesh->GetIndexBuffer(&ib));         // Get the indices of the picked triangle.         DWORD* indices = 0;         SIZE_T size;         HR(ib->Map((void**)&indices, &size));                  DWORD i0 = indices[inf];              HR(ib->Unmap());         // Get the vertices of the picked triangle and copy them into our VB.         MeshVertex* vertices = 0;         HR(vb->Map((void**)&vertices, &size));         D3DXVECTOR3* triVerts = 0;                  HR(mPickedTriVB->Map(D3D10_MAP_WRITE_DISCARD, 0, (void**)&triVerts));                  triVerts[0] = vertices[i0].pos;                  mPickedTriVB->Unmap();         HR(vb->Unmap());         ReleaseCOM(vb);         ReleaseCOM(ib);         // Render the picked triangle specially to distinguish it         // from the other triangles.         md3dDevice->IASetInputLayout(InputLayout::Pos);         md3dDevice->IASetPrimitiveTopology(D3D10_PRIMITIVE_TOPOLOGY_POINTLIST);         UINT stride = sizeof(D3DXVECTOR3);         UINT offset = 0;         md3dDevice->IASetVertexBuffers(0, 1, &mPickedTriVB, &stride, &offset);         D3D10_TECHNIQUE_DESC techDesc;         mPickedTech->GetDesc( &techDesc );         D3DXMATRIX W = mBaseWorld;         D3DXMATRIX V = GetCamera().view();         D3DXMATRIX P = GetCamera().proj();         D3DXMATRIX WVP = W*V*P;         mfxPickedWVPVar->SetMatrix((float*)&WVP);         for(UINT i = 0; i < techDesc.Passes; ++i)         {             ID3D10EffectPass* pass = mPickedTech->GetPassByIndex(i);             pass->Apply(0);             md3dDevice->Draw(1, 0);         }     } }     .

    Picking Intersection Vertices

    Still having issues getting this to work, I tried to get the shortest distance from the mouse click but its not working right. Just want the closest vertex to be selected from click on the triangle   void PickingApp::pick(int sx, int sy) { D3DXMATRIX P = GetCamera().proj(); // Compute picking ray in view space. float vx = (+2.0f*sx/mClientWidth - 1.0f)/P(0,0); float vy = (-2.0f*sy/mClientHeight + 1.0f)/P(1,1); D3DXVECTOR3 rayOrigin(0.0f, 0.0f, 0.0f); D3DXVECTOR3 rayDir(vx, vy, 1.0f); // Tranform to world space. D3DXMATRIX V = GetCamera().view(); D3DXMATRIX inverseV; D3DXMatrixInverse(&inverseV, 0, &V); D3DXVec3TransformCoord(&rayOrigin, &rayOrigin, &inverseV); D3DXVec3TransformNormal(&rayDir, &rayDir, &inverseV); // Transform to the mesh's local space. D3DXMATRIX inverseW; D3DXMatrixInverse(&inverseW, 0, &mBaseWorld); D3DXVec3TransformCoord(&rayOrigin, &rayOrigin, &inverseW); D3DXVec3TransformNormal(&rayDir, &rayDir, &inverseW); ID3DX10Mesh* d3dxmesh = mBaseMesh.d3dxMesh(); MouseCoord = rayOrigin; UINT hitCount; float u,v,t; ID3D10Blob* allHits; d3dxmesh->Intersect(&rayOrigin, &rayDir, &hitCount, &mPickedTriangle, &u, &v, &t, &allHits); ReleaseCOM(allHits); } drawScene(){ ... ... DWORD i0 = indices[mPickedTriangle*3+0]; DWORD i1 = indices[mPickedTriangle*3+1]; DWORD i2 = indices[mPickedTriangle*3+2]; HR(ib->Unmap()); // Get the vertices of the picked triangle and copy them into our VB. MeshVertex* vertices = 0; HR(vb->Map((void**)&vertices, &size)); D3DXVECTOR3* triVerts = 0; HR(mPickedTriVB->Map(D3D10_MAP_WRITE_DISCARD, 0, (void**)&triVerts)); float v1 = sqrt((pow(vertices[i0].pos.x - MouseCoord.x ,2) + pow(vertices[i0].pos.y - MouseCoord.y,2) + pow(vertices[i0].pos.z - MouseCoord.z,2))); float v2 = sqrt((pow(vertices[i1].pos.x - MouseCoord.x ,2) + pow(vertices[i1].pos.y - MouseCoord.y,2) + pow(vertices[i1].pos.z - MouseCoord.z,2))); float v3 = sqrt((pow(vertices[i2].pos.x - MouseCoord.x ,2) + pow(vertices[i2].pos.y - MouseCoord.y,2) + pow(vertices[i2].pos.z - MouseCoord.z,2))); if(v1 < v2 && v1 < v3) triVerts[0] = vertices[i0].pos; if(v2 < v1 && v2 < v3) triVerts[0] = vertices[i1].pos; if(v3 < v1 && v3 < v2) triVerts[0] = vertices[i2].pos; ...}
  3. I am trying to grab the closest vertex to my mouse click using picking. I understand that the &t represents distance, but how can I get the distance of each vertex from the mouse click after converting it all to the correct worlds I am able to select the faces of the mesh, but am struggling on selecting the closest vertex.   UINT hitCount; float u,v,t; ID3D10Blob* allHits; d3dxmesh->Intersect(&rayOrigin, &rayDir, &hitCount, &PickedTriangle, &u, &v, &t, &allHits); I know the vertex is going to be vertex[indices[PickedTriangle*3+0]] ..etc. So how can I get the distance from the click for each vertex in the triangle selected.
  4. I have set up this alphamap terrain that does multiple textures which works correctly except the textures seem off. The more you zoom out the more it the textures seem repeated. I believe this is because of the uv coordinates, looking for help on how to fix it as I am lost.
