  • As you know, we have released shader effects #11 - Normal Mapping, #12 - Plasma, and #13 - Voronoi. Because, of concerns with using Patreon, I have decided to return to the conventional approach of sharing my shader effects with the Scirra 2 Community.

    You can therefore now download the shader effects + accompanying demo file from here:

    If you like what I have done so far, please support me on my Patreon page (you can download the same files there). I also welcome any donations sent my way (care of my website).

    One last thing to note - From shader #11 onwards, please abide by Creative Commons Attribution 4.0 International License. Explanations can be found by following the link.

    Thank you for the interest in my shader effects. Enjoy!

  • Ok... noted your suggestions. Possibly a pack of special effects then. Or I can just stick with regular donations (though I have never ever seen that moving before).

  • And if anyone has shader requests, let me know.

  • Done... please test and see if you can download both the Plasma and Voronoi shader effects... for free, as long as you are a patron.

  • Ok... got it. I think I know what to do then.

  • Click on "Be a patron" and choose "No Reward" and let me know if you cannot get the shader demo from over here. I'm still playing around with the Patreon settings and haven't tested all options yet. Thanks.

  • Thanks!

  • We have released shader effect #13 - Voronoi Effect. Please head over to our website to see the demo in action.

    In case any one does ask, the shader zip file is absolutely free for the Scirra 2 community. If you want the zip file, just head over to our Patreon page, select to become a patron and choose "No Reward". You pay nothing - $0. Zip. Nada. And you get access to all our stuff put up on Patreon for free. But, really it's entirely up to you.

  • Follow the second link I have added in the very first message.

  • Finally to add a blurring effect a few pixels behind, change line 5 of main() from this:

    vec3 c = sample(0, 0) * dot(n, normalize(lp - sp));[/code:35j7by3f]

to this:

[code:35j7by3f]vec3 c = sample(0, 5) * dot(n, normalize(lp - sp));[/code:35j7by3f]

Come to think it, to make a cel shading like effect, change the same line to something like this:

[code:35j7by3f]vec3 c = normalize(sample(0, 4) * dot(n, normalize(lp - sp)) + sample(0, 5) * dot(n, normalize(lp - sp)));[/code:35j7by3f]

  • One more modification I can suggest is to make a searchlight effect emanating from the center of the screen, change the second line of code for main():

    vec3 ep = vec3(iResolution.x * .5, (iResolution.y) * .5, 500.);[/code:22rflasc]

to this new version:

[code:22rflasc]vec3 ep = vec3(iResolution.x * .5, (iResolution.y) * .5, 100.);[/code:22rflasc]

  • Another modification you can do is to make the 3D effect more pronounced. Just change these lines from this:

    #define OFFSET_X 1
#define OFFSET_Y 1[/code:bsi7fvzi]

to this:

[code:bsi7fvzi]#define OFFSET_X 2
#define OFFSET_Y 2[/code:bsi7fvzi]

  • It's always good to hear another person's suggestion though... no negativity intended. And yes, there's no requirement for a normal map, like say as a second frame in an animation. That would have been a big headache to implement.

    Anyway, for sharing - here's a way of making things even brighter, just replace the last line of code in the fx file with this:

    gl_FragColor = texture2D(samplerFront, vTex) + lightintensity * vec4(c, gl_FragColor.a);[/code:r1slkjev]

Also add in this as line 16 in the fx file:

[code:r1slkjev]uniform float lightintensity;[/code:r1slkjev]

Next, insert the xml file with this entry near the end:

[code:r1slkjev]<param>
	<name>Light Intensity</name>
	<description>Use values from 1.0 to 50.0... Default value of 1.0</description>
	<type>float</type>
	<initial>1.0</initial>
	<uniform>lightintensity</uniform>
</param>[/code:r1slkjev]

This inserts a new effect parameter known as lightintensity.

  • Please change what you like in the fx code and share with us something that is "ready to be used in a game". What new features would you consider adding in to make it reach that state?
