question about Ch08_02Particles/ParticleRenderer.cs
hi i have questions there is a line of code this.ParticlesPerBatch = (int)(maxParticles * 0.0128f); how did you derived the 0.0128 value? and what is the "limiter"? i still can't understand it thanks peter
@shadercoder primarily this is just a constant value I chose based on achieving a suitable rate of new particles vs those that are already alive that appealed visually. The limiter and the ParticlesPerBatch work together in this way. E.g. I wanted the snow fall to be consistent with no "gaps" in the fall.
The limiter is the time in seconds between each round of "particle generation".
I could have chosen a more elegant or easy to understand solution to this - but I think at the time I had achieved the look I was after :)
You do have to be careful about the maximum value as the ParticlesPerBatch is used within the context.Dispatch call which has a max value of 65535.
