Zip up your submissions with your NYU id as the file name (e.g. rn47.zip) and upload them to this google drive folder by next class. Include comments to explain your reasoning or struggles. Remember that your best efforts and attempts are what counts the most! We will discuss this on Monday.

Using what we started in class write a fire effect by adding manipulating the size, color, opacity, and position of the particles over time.

Add the following code to Program.cs to enable additive blending which we haven't talked about but will look at next week.

p.BlendingFunction.SourceFactor = BlendingFactor.SrcAlpha;
p.BlendingFunction.DestinationFactor = BlendingFactor.One;

How many particles can you push before quality degrades?

  1. Optional Move as much of the effect onto the GPU as possible
  2. Optional Add smoke to the fire in the same effect (turn the particles gray and white later in their "life")
  3. Optional Use the mouse position (w.MousePosition) to affect the particles
  4. Optional Experiment with different values for BlendingFunction.SourceFactor and BlendingFunction.DestinationFactor, how do they affect the render?
