Hello all,

I have seen this demo using the Flint engine: http://flintparticles.org/examples/logo-firework
According to the documentation, Flint can make a zone from a bitmap.

Question: can Spark make a zone from a bitmap as well? (according to the Spark docs, i think not - but i could be wrong as a newbie to Spark)
Would Spark be able to do the same effect?

Thanks

Hi,

unfortunately, no you cannot at the moment.

But as SPARK is a 3D particle engine and not a 2D as Flint, it does not make a lot of sense to have a zone representing a bitmap (however it can be useful anyway when using it in 2D)

But it is not the highest priority at the moment and having a zone representing a mesh for instance will be a lot more useful than a zone representing a texture.

Anyway, it is a good idea (even if a bit too specific i think) and I keep it in a corner of my head for later maybe.

Hello Juff,

Thanks for the reaction.
Say, if would make a zone class myself that accepts an 8 bit gray-scale bitmap as input parameter, and generate particles only in the non-black areas, would :
a) Spark be able to animate the particles like in the demo below? (if so, how would it be done)
b) you accept the code? (so that I do not have to maintain it separately)

PS I appreciate the difference between a 2D and 3D particle engine, but it should easier to do 2D in a 3D environment that vice versa. (cfr the writing demo, which is AFAIK 2D oriented as well)
