New feature - Anaglyph Glasses

Hi for all!!!! happy to be writing my first post =)

Recently, I started studying anaglyph images and thought of a way to help the emulation of the 3D effects of the master system (edit: on meka with support Red-Cyan Glasses)

i made those images with 2 consecutive frames of each game(screenshot by MEKA) with fews color transforms using a formula like this:


(http://www.truevision3d.com/forums/indevelopment/redcyan_anaglyph_stereoscopy_depth_of_field-t19288.0.html)

with Red-Cyan glasses, those images will don't have the same color as in master system but the depth amount will be the same!!!! =)


i think if a graphics filter that work like Hq2x filter, eagle doing this color transformation maybe works to do this effect in "emulation time"=)

can anyone help me in this adventure to write such filter for MEKA?

This feature is already available in other emulators; for the SMS, Dega and Cogwheel support anaglyph glasses.

already tried.... =(

i think the results can be better with colors closer to the original

in Cogwhell, one of the methods doesn't remove the existing colour information from the frames .For example, the red text is invisible through the green filter, but strongly visible through the red filter, making it shimmer.the other results in a grey image.

in dega the colours are too different of original





and... for me.. MEKA is best 8-bit sega emulator and deserves the best image with anaglyph glasses =)

Would be quite funny to add the feature. Now that MEKA works in true color mode it shouldn't be very difficult to add a filter to do that.

sorry for the delay in feedback, but my work has consumed all my time in the last week

need help to find the output of the two perspectives

would be *screenbuffer_1, *screenbuffer_2 ?

this is the code I wrote in the adobe pixel bender to make the images above:

{
input image4 src1;
input image4 src2;

output pixel4 dst;

void
evaluatePixel()
{
dst.r = sampleNearest(src1,outCoord()).r * 0.1 + sampleNearest(src1,outCoord()).g * 0.7 + sampleNearest(src1,outCoord()).b * 0.2;
dst.g = sampleNearest(src2,outCoord()).g * 0.9;
dst.b = sampleNearest(src2,outCoord()).b * 0.8;
}
}

Hello,

I tried Cogwheel, but I was unable to see the stereoscopic effect with the color anaglyphs: it works only with monochrome.

Hello,

I made a shader for the RetroArch emulator, in order to play active shutter stereoscopic 3D games with red/cyan glasses.

You can find more information here:

Sample screenshot:


You're encouraged to download. This seems to work rather better than Cogwheel, since I've tried to preserve original SMS colors without breaking the stereoscopic effect.

Enjoy!
