OpenDX mesh visualization intro

Step 1: Grid construction and edges visualization

grid = Construct(origin=[-10,-10,-10], 
                 deltas=[4,4,4], counts=[5,5,5]);
edges = ShowConnections(grid);
camera = AutoCamera(edges, "off-diagonal");
Display(edges, camera);
KeyIn("Hit any key to exit");

Step 2: Showing grid boundary

grid = Construct(origin=[-10,-10,-10], 
                 deltas=[4,4,4], counts=[5,5,5]);
edges = ShowConnections(grid);
boundary = ShowBoundary(grid);
camera = AutoCamera(edges, "off-diagonal");
Display(edges, camera);
KeyIn("Hit any key to exit");
Display(boundary, camera);
KeyIn("Hit any key to exit");

Step 3: Showing edges on boundary only

grid = Construct(origin=[-10,-10,-10], 
                 deltas=[4,4,4], counts=[5,5,5]);
boundary = ShowBoundary(grid);
edges = ShowConnections(boundary);
camera = AutoCamera(edges, "off-diagonal");
Display(edges, camera);
KeyIn("Hit any key to exit");

Step 4: Showing edgs as tubes

grid = Construct(origin=[-10,-10,-10], 
                 deltas=[4,4,4], counts=[5,5,5]);
boundary = ShowBoundary(grid);
edges = ShowConnections(boundary);
edges = Tube(edges, diameter=0.5);
edges = Color(edges, "orange");
camera = AutoCamera(edges, "off-diagonal");
Display(edges, camera);
KeyIn("Hit any key to exit");

Step 5: Superimposing boundary and edges

grid = Construct(origin=[-10,-10,-10], 
                 deltas=[4,4,4], counts=[5,5,5]);
boundary = ShowBoundary(grid);
edges = ShowConnections(boundary);
edges = Tube(edges, diameter=0.5);
edges = Color(edges, "orange");
be = Collect(boundary, edges);
camera = AutoCamera(edges, "off-diagonal");
Display(be, camera);
KeyIn("Hit any key to exit");

Step 6: Showing node glyphs

grid = Construct(origin=[-10,-10,-10], 
                 deltas=[4,4,4], counts=[5,5,5]); 
boundary = ShowBoundary(grid);
edges = ShowConnections(boundary);
edges = Tube(edges, diameter=0.5);
edges = Color(edges, "orange");
points = ShowPositions(boundary);
points = AutoGlyph(points, type="sphere", 
                   scale=1.0, ratio=1.0);
points = Color(points, "blue");
be = Collect(boundary, edges, points);
camera = AutoCamera(points, "off-diagonal");
Display(be, camera); 
KeyIn("Hit any key to exit");

Step 7: Using cutting plane

grid = Construct(origin=[-10,-10,-10], 
                 deltas=[4,4,4], counts=[5,5,5]);
boundary = ShowBoundary(grid);
edges = ShowConnections(boundary);  
edges = Tube(edges, diameter=0.5);
edges = Color(edges, "orange");
points = ShowPositions(boundary);
points = AutoGlyph(points, type="sphere", 
                   scale=1.0, ratio=1.0);
points = Color(points, "blue");
boundary = ClipPlane(boundary, normal=[0,1,1]);
be = Collect(boundary, edges, points);
camera = AutoCamera(points, "off-diagonal");
Display(be, camera); 
KeyIn("Hit any key to exit");
