 Well, i told you guys i would release a first version of shade-c this week, so here it is: shade-c version: 0.87 "FLU" BETA I couldn't get everything done i wanted as i was (and still am) ill for the last couple of days, but some things are already implemented. Current Features: - High Dynamic Range Rendering - Depth of Field with dynamic autofocus - Easily attach more Post Processing Effects, set their mtl.skills and mtl.skins (works with the PPEs supplied with A7) - Small library of ready to use Post Processing Effects (including heat haze, a toon- and sketch shader) - Ready to use object shaders (including velvety, carpaint and a skin shader) - lite-c only, no plugins are used - easy integration to do list: - include dynamic hdr gamma correction - include volumetric sunlight shader - include volumetric particle shader - get ambience occlusion to work - include ambience occlusion shader - add vecSkill vars to object shaders and write a function to easily set them - clean up object shaders - finish vector art shader and implement it - add more shaders (let me know what you want): + "number 23"-like post processing effect - finish manual - fix bugs/make shade-c more user friendly/etc. - everything else i forgot Grab it here (There's also a compiled testapp) I hope there aren't too many bugs in the code and typos in the manual. Well then, enjoy and give feedback please

WHOAW This is the right stuff at the right time. I really wanted to start in the next few hours to add these shaders on my own but you were first ^^ [EDIT] Is there a way to switch through the shaders in the test bed? [EDIT2] Quote:
IMPORTANT NOTE: shade-c uses entity.skills89-99. Make sure they aren't used by your project!
This is bad. Why don't you use a linked datastructure to reduce the necessary skills to 1 ???
[EDIT3]
I noticed that you use 5 or 6 stages for HDR. Isnt it possible to reduce it to one shader? Wouldnt this also increase rendering speed?
Can s_mtl_hdrColor be used to add a color filter to the scene?
[EDIT4]
Could you please describe in short how I can extract the DOF and HDR shader from your framework to integrate them into my own?

No, sorry. But good point, i will keep that in mind for the next version.

What do you mean by linked datastructure? An array? Reducing the needed skills to 1 would be great.

Yessum i use 6 stages.
1 stage: downsample the scene for speed reasons.
2 stage: do a highpass
3 stage: blur the screen (gaussian i think, i always mix box and gaussian)
4 stage: horizontal blur
5 stage: vertical blur
6 stage: upsample and combine hdr with the scene (tonemapping)
so basically you could cut this down to 4 stages, by not using the horizontal and vertical blur.
If you know a way to do HDR in one pass i would be more than interisted in this
s_mtl_hdrColor is a remaining of my testscene. It's not used by anything ad has no purpose. Thanks for pointing it out.
Applying a color filter to the final hdr stage sounds like a good idea however.

I'll have a look at it, but it shouldn't be to much work. But not today, i'm too tired.

Good testbeds allow the user to see everything your <insert app.. in this case shade-C> features. If you are too tired to make a super-adjustable thing, make different demos or different "pages"/"scenes" with different shaders.

It seems that you are storing data in these skills. Though, saying the user that these skills are unavoidable used by shade-C makes a bitter taste on the tongue :-) I was in same situation some weeks ago: for a customer I made a plugin. At first there were only 6 skills I needed, after some development iterations I used over 30 skills to save and log running data which very necessary and not able to be reduced anymore. So I created a struct which holds the data and write the adress of the struct into only one skill. The co-routine which works on that entity with this data than restores by casting each frame a pointer to that datastructure. To remove the entity I wrote a special function which checks if the linking skill is != 0. If yes, the entity is using that plugin and the linked datastructure, so it removes it first and after that ent_remove is called. Easy, isnt it?

I will investigate that later when I figured out how to rip HDR from your "framework".

That would be nice if you can add this comes in handy when you are programming day/night cycles, like giving the scene a blue touch at night and a warm orange tone when its sunrise.

[EDIT]
Maybe you can add a function that removes all stages.

Reading this it comes to my mind: what about fog, do your shaders work with fog, too?

Agh, it doesn't work for me  . I'm running gamestudio pro a7. When I try to run my game it says: Code:
Error in 'MAIN' line 13: 'var' undeclared identifier
< var s_rtScale = 256; //render-target size>
<include ^s_shadeC.c>;>
MAIN.WDL 1:2 (): Script error s_shadeC.c
All I did was include the s_shadec.c file and call s_initshaders

this is cool, now if only you could take the sketch shader, and add the models skins to it with toon shading, it'd be perfect, also since i don't have lite-c i can't use this, but when i get a7 i'll probably get it on the first day edit: i noticed that you kinda did it with the toon shader, but maybe witout bloom it would look better
