Detailed Description

Lightweight RVO Circle Example.

Lightweight script for simulating agents in a circle trying to reach their antipodal positions. This script, compared to using lots of RVOAgents shows the real power of the RVO simulator when little other overhead (e.g GameObjects) is present.

For example with this script, I can simulate 5000 agents at around 50 fps on my laptop (with desired simulation fps = 10 and interpolation, 2 threads) however when using prefabs, only instantiating the 5000 agents takes 10 seconds and it runs at around 5 fps.

This script will render the agents by generating a square for each agent combined into a single mesh with appropriate UV.

A few GUI buttons will be drawn by this script with which the user can change the number of agents.

Member Function Documentation

static Color HSVToRGB ( float  h, float  s, float  v  )

staticprivate

Converts an HSV color to an RGB color, according to the algorithm described at http://en.wikipedia.org/wiki/HSL_and_HSV.

Parameters

h,s,v

the color to convert.

Returns

the RGB representation of the color.

Here is the caller graph for this function:

Member Data Documentation

float exampleScale = 100

How large is the area where agents are placed.

For e.g the circle example, it corresponds

Vector3 renderingOffset = Vector3.up*0.1f

Offset from the agent position the actual drawn postition.

Used to get rid of z-buffer issues
