# Get the "Torus01" object and its polygons/faces polygonObject = scene.getObject("Torus01") polygons = polygonObject.getFaces() # Print out the "Torus01" node's number of polygons scene.message("Number of polygons: "+str(len(polygons))) |

Get a torus object's polygons, store them in a list container, and get the three vertices of each polygon. Print out their Ids:Then, calculate each polygon's midpoint and place a particle there:

# Get the "Torus01" object, its faces, and vertices
# Define a null position
# Get the "Container01" node
polygonObject = scene.getObject("Torus01")
polygons = polygonObject.getFaces()
vertices = polygonObject.getVertices()
vertexPosition = Vector.new(0,0,0)
container = scene.get_PB_Emitter("Container01")
# Loop through the polygons
for polygon in polygons:
# Indices are the current polygon's vertices
# Get the three individual vertices
vertexIndices = polygon.getIndices()
vertex0 = vertices[vertexIndices[0]]
vertex1 = vertices[vertexIndices[1]]
vertex2 = vertices[vertexIndices[2]]
# Get the individual vertex positions
vertex0Pos = vertex0.getPosition()
vertex1Pos = vertex1.getPosition()
vertex2Pos = vertex2.getPosition()
# Add the three position vectors
# Calculate the XYZ averages and apply them to the vertexPosition vector
vertexPosition = vertex0Pos + vertex1Pos + vertex2Pos
vertexPosition.set(vertexPosition.x / 3.0, vertexPosition.y / 3.0, vertexPosition.z / 3.0)
# Add a particles at vertexPosition with velocity 0
container.addParticle(vertexPosition, Vector.new(0,0,0)) |
