A psychrometric chart is a graphical representation of the psychometric processes of air. Psychrometric processes include physical and thermodynamic properties such as dry bulb temperature, wet bulb temperature, humidity, enthalpy, and air density. A psychrometric chart can be used in two different ways. The first is done by plotting multiple data points, that represent the air conditions at a specific time, on the chart. Then, overlaying an area that identifies the “comfort zone.” The comfort zone is defined as the range within occupants are satisfied with the surrounding thermal conditions. After plotting the air conditions and overlaying the comfort zone, it becomes possible to see how passive design strategies can extend the comfort zone.

Slope Elevation
Slope elevation is done using the point of terrain mesh to obtain the distance between highest and lowest point. Obtained domain is used to get color gradient on the terrain mesh.
Slope Degree
Slope degree is done by dividing the terrain surface in equal U and V count, then surface normals of subdivided surfaces are used to determine the angle at which each surface is placed. 33

A tool draws an interactive bubble diagram and a set of tools reveal feasible geometric interpretations of the proposed bubble diagram in terms of plan layout graphs. Offering real-time Space Syntax analyses at the same time, the tools provide feedback on the spatial performance, which is translatable into the likely social performance of the plan layout patterns. The subtle fact about a bubble diagram is that it is a comprehensible con-figurative tool for designers and at the same time for computer programs and that it does not suggest a single geometric form. Bubble diagrams convey very important meanings that may not be seen easily by bare eyes; for instance they implicate which spaces are to be relatively private and which ones are to be communal and much more.

N Integration is a normalised measure of distance from any a space of origin to all others in a system. In general, it calculates how close the origin space is to all other spaces, and can be seen as the measure of relative asymmetry (or relative depth)

CHOICE/BET WEENNESS
Network Analysis
N In graph theory, betweenness is a measure of centrality in a graph based on shortest paths. For every pair of vertices in a connected graph, there exists at least one shortest path between the vertices such that either the number of edges that the path passes through or the sum of the weights of the edges is minimized. The betweenness centrality for each vertex is the number of these shortest paths that pass through the vertex.

Agent Based Modeling
Physarum polycephalum, literally the “many-headed slime”, is a slime mold that inhabits shady, cool, moist areas, such as decaying leaves and logs. P. polycephalum is one of the easiest eukaryotic microbes to grow in culture, and has been used as a model organism for many studies involving amoeboid movement and cell motility. For example, a team of Japanese and Hungarian researchers have shown P. polycephalum can solve the Shortest path problem. When grown in a maze with oatmeal at two spots, P. polycephalum retracts from everywhere in the maze, except the shortest route connecting the two food sources. Which in this case railway stations in Sydney(33O86’4’’ N / 151O22’14’’W) are considered as food and various nodes act as food. In order to determine the shortest path between railway stations and selected nodes.

QUELEA
6.2Agent Based Modeling The Red-billed Quelea is restricted to Africa where it occurs in semi-arid areas,feeding principally on native grasses but when these are scarce the birds will attack the seedheads of crops. In this case it allows to create complex simulations, analyses, and forms through the combination of simple rules. Quelea provides an intuitive interface to experiment with particle systems, agents/boids, braitenberg vehicles, and everything in-between and beyond. The orange dot in the diagram is the emitter and white box around it acts as the environment. Movement of quelea partials happens inside this box whit 0.025 force in Z direction.
