C++ (Cpp) SelectionTest::TestTriangles Examples

Example #1

File: MD5Surface.cpp Project: BielBdeLuna/DarkRadiant

// Selection test
void MD5Surface::testSelect(Selector& selector,
							SelectionTest& test,
							const Matrix4& localToWorld)
{
	test.BeginMesh(localToWorld);

	SelectionIntersection best;
	test.TestTriangles(
	  vertexpointer_arbitrarymeshvertex(_vertices.data()),
	  IndexPointer(_indices.data(), IndexPointer::index_type(_indices.size())),
	  best
	);

	if(best.valid()) {
		selector.addIntersection(best);
	}
}

Example #2

File: RenderablePicoSurface.cpp Project: DerSaidin/DarkRadiant

// Perform selection test for this surface
void RenderablePicoSurface::testSelect(Selector& selector,
									   SelectionTest& test,
									   const Matrix4& localToWorld) const
{
	if (!_vertices.empty() && !_indices.empty())
	{
		// Test for triangle selection
		test.BeginMesh(localToWorld);
		SelectionIntersection result;

		test.TestTriangles(
			VertexPointer(&_vertices[0].vertex, sizeof(ArbitraryMeshVertex)),
      		IndexPointer(&_indices[0],
      					 IndexPointer::index_type(_indices.size())),
			result
		);

		// Add the intersection to the selector if it is valid
		if(result.valid()) {
			selector.addIntersection(result);
		}
	}
}
