Get a torus object's polygons, store them in a list container, and print out their number:

Code Block

language	py

# 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 vertices, store them in a list container, and print out their number:

Code Block

language	py

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

...

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

Code Block

language	py

# 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 vertexPositions = 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()
 
	vertexPositions

	# Add the three position vectors
	# Calculate the XYZ averages and apply them to the vertexPosition vector
	vertexPosition = vertex0Pos + vertex1Pos + vertex2Pos
 	vertexPositionsvertexPosition.set(vertexPositionsvertexPosition.x / 3.0, vertexPositionsvertexPosition.y / 3.0, vertexPositionsvertexPosition.z / 3.0)

	# Add a particles at vertexPosition with velocity 0	 
	container.addParticle(vertexPositionsvertexPosition, Vector.new(0,0,0))
