A quick question about Plasma from CC

Discussion and feedback on Construct 2

Post » Sat Jun 15, 2013 7:59 am

I know it's a DirectX thing, but It might be possible with WebGL, Are you going to add Plasma effect like CC in C2?

How does that effect look ?

I used a "trick" in Drop da piew to get a somewhat plasma effect (in my opinion) using several tiled backgrounds with sine behaviors and playing with the tone color and opacity of each background.

Also doesn't the "Water" webGL effect allow for a similar effect ?

It's not really like water, it's more of a blurred trail effect.
The plasma examples start at 0:55 in this video:

I think those plasma effects are all using interferences between two textures using a texture srt in greyscale. Afterwards a color ramp is applied to the resulting frame.
The motion blur is some per pixel thingy I guess. You can dive into this by checking some 90ies demoscene stuff (futurecrews second reality demo is a good example)

rock on,

EDIT: Some effects I tested out :

@Grave The problems are that you are using a lot of resources, the result of fps was not perfect, compared to CC (Construct Classic) which also uses distortion and subtraction to pattern effects, it would look like smoothing effect as R0j0hound said, Plasma is like realistic natural effects like fire, lightning, etc.. comes the color filters that can change colors in real time.

PD: Nice art!
