Fire and Helicopter Issue


question 1
I want to make a fire, but do not know where to start. I guess you need a particle emitter and change the particles to flames but it stil looks terrible
any idea ?

question 2
We created a city and sort of virtual park. A helicopter is flying in the city. Picking random points in the 3d grid (within certain limits) but the problem is this. The helicopter is flying trough the buildings. Ghost busters

So how can i predict that the random point is not in the building ? And something to ease in ease out function would be nice

That's it for now

Thanks in advance

1) You can create a video of a fire and apply that to a billboarded quad. I believe this is what most video games do. The difficult part is creating the video of the fire. You might be able to find some animated fire textures on TurboSquid or other similar sites.

2) You can use the viz.intersect() command to determine if a line goes through an object. So take your random point and create a line that extends upward, then check if this line intersects with your building.
