            <title>[MC-9095] Red of 3D Anaglyph mode is not the same as the standard color of 3D glasses</title>
                <link>https://bugs.mojang.com/browse/MC-9095</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;This isn&apos;t really a gameplay bug, but the 3D anaglyph&apos;s red shade is not the same as the standard color of 3D glasses. I don&apos;t think it is may glasses because all other 3D anaglyphs work fine.&lt;/p&gt;</description>

If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.&lt;/p&gt;</comment>
                            <comment id="243601" author="achimb" created="Tue, 18 Aug 2015 18:18:05 +0200"  >&lt;p&gt;@Tim Weber: Can you provide screenshots of other games you mentioned, so I can compare them to the Minecraft rendered ones? Would be interesting to see what makes the difference (make sure they also have the high contrast of white areas against dark surroundings). TIA!&lt;/p&gt;</comment>
                            <comment id="243567" author="timwe1912" created="Tue, 18 Aug 2015 14:50:22 +0200"  >&lt;p&gt;I have to disagree. Minecraft might do the color separation technically correct in the way you explained it has to work, though I do not have these issues when playing other games in 3D anaglyph mode. This shows that it can be done without these ghost effects and that it is not the glasses&apos; fault. The ghosting only stands out when you are looking at bright things like the white sheep in the first screenshot, and it also is clearly visible in your screenshot if you look at the white window frames through the red glass of your anaglyph glasses.&lt;/p&gt;

&lt;p&gt;TL;DR: Achim might be right about technical aspect, that does not change anything about the issue being there -&amp;gt; not resolved&lt;/p&gt;

                            <comment id="243513" author="achimb" created="Tue, 18 Aug 2015 05:51:08 +0200"  >&lt;p&gt;If you take a look at the red/green/blue channels of the attached screenshot (e.g. with Photoshop) you can see that the separation is correctly done by Minecraft: red channel for left eye, blue channel for right eye and green channel filled with the right eye image to support its brightness. The problem with anaglyph glasses is that the red filter often tend to not only let the red channel pass, but also some of the green, so that your left eye also see 80% left eye image and 20% right eye image. This is true for the blue filter too. (Actutally this helps to get more realistic colors in your brain, but produce the ghosting!). Shifting hue of the image doesn&apos;t help at all, because you are then moving color information from the blue channel to the red channel and vis versa producing even more ghosting because your glasses can only filter red and blue. You can&apos;t do an &quot;orange/purple&quot; anaglyph image with your computer screen, because it only emits red/green/blue colors, you won&apos;t be able to separate &quot;orange&quot; and &quot;purple&quot; into two separate images for your left eye and your right eye anymore, because those information is mixed into all three channels that are available only. So what you need is a sharper &quot;red&quot; filter that don&apos;t let green or blue light through it to not see those channels with the left eye. Make sense?&lt;/p&gt;

&lt;p&gt;I consider this bug as &quot;resolved&quot; because Minecraft does the color separation correctly.&lt;/p&gt;</comment>

                            <comment id="207722" author="rocketturtle" created="Tue, 4 Nov 2014 04:54:35 +0100"  >&lt;p&gt;I can confirm that the issue is still present in 1.8.1 Prerelease 3 and Launcher version 1.5.3.&lt;/p&gt;

&lt;p&gt;The behavior I&apos;m seeing is ghosting of the blue channel into the red channel.  It&apos;s easiest to see by looking at a light colored object, like an oxeye daisy or a torch, and closing the &apos;blue&apos; eye.  This way you only see the red channel, and the blue ghosts.&lt;/p&gt;</comment>
                            <comment id="130903" author="rocketturtle" created="Sun, 12 Jan 2014 13:42:51 +0100"  >&lt;p&gt;Still going on in 14w02c, as well.&lt;/p&gt;

&lt;p&gt;@ Grum:  I know you&apos;ve said in the past that you guys wouldn&apos;t be focusing much effort to fixing such a novelty feature like 3D anaglyph mode, but since we all don&apos;t have Oclus Rifts, it&apos;s the most accessible way to see Minecraft in 3D.  Even in it&apos;s current state, it&apos;s a pretty amazing experience.  I&apos;d like to humbly ask you guys to reconsider.&lt;/p&gt;</comment>

                            <comment id="93120" author="drredstoner" created="Sat, 20 Jul 2013 09:33:50 +0200"  >&lt;p&gt;I can confirm that this is an issue still in 1.6.2.&lt;/p&gt;</comment>
                            <comment id="59455" author="timwe1912" created="Mon, 8 Apr 2013 22:51:58 +0200"  >&lt;p&gt;Just checked if it is still occuring (release 1.5.1), and indeed it did not change. What makes it look blurry is the picture thats supposed to be only visible for the cyan glass (right eye) is not being filtered completely by the red glass, so that you see kind of both pictures through the red glass (left eye), just like you would when you look at the screen without glasses. The picture for the right eye works fine though.&lt;br/&gt;
If you need any more information feel free to ask, I would love to see this issue being fixed since I bought a 3D-Anaglyph Glass to play MC in 3D-mode.&lt;/p&gt;</comment>

If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.&lt;/del&gt;&lt;/p&gt;</comment>
                            <comment id="45410" author="timwe1912" created="Tue, 12 Feb 2013 13:32:56 +0100"  >&lt;p&gt;Confirmed, always thought it would be my glasses but these work fine in other games. Please vote it up, playing in 3D-anaglyph mode is no fun this way!&lt;/p&gt;</comment>
                            <comment id="44923" author="javimau5" created="Sun, 10 Feb 2013 01:21:55 +0100"  >&lt;p&gt;Confirmed! I can see some of blue channel with my glasses. I have taken the photo with my mobile and the glasses&lt;/p&gt;</comment>
                            <comment id="43441" author="cubethethird" created="Mon, 4 Feb 2013 13:25:37 +0100"  >&lt;p&gt;The colours look fine to me. I do agree that there is a &apos;ghost&apos; image appearing, but that isn&apos;t caused by the colours (see &lt;a href=&quot;https://bugs.mojang.com/browse/MC-4262&quot; title=&quot;3D Anaglyph image seperation too large&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-4262&quot;&gt;&lt;del&gt;MC-4262&lt;/del&gt;&lt;/a&gt;).&lt;/p&gt;</comment>

                            <comment id="43251" author="grum" created="Sun, 3 Feb 2013 22:14:54 +0100"  >&lt;p&gt;I do not think we&apos;ll be fixing such novelty things &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/biggrin.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;</comment>

&lt;p&gt;Steps to reproduce:&lt;br/&gt;
Turn 3D anaglyph on (Esc&amp;gt;Options&amp;gt;Video Settings)&lt;br/&gt;
place a snow block (Because it is the closest to white as possible)&lt;br/&gt;
You will notice that the red is brighter than you would expect it to be&lt;/p&gt;</comment>
