Is Juneteenth an illusion claiming the liberation of black people?

No.  The end of slavery is different from the continuation of discrimination against African Americans. 

Juneteenth is the oldest nationally celebrated commemoration of the end of slavery in the United States.Slaves in Texas weren’t actually freed until the arrival of Union troops in Galveston, Texas on June 19, 1865, although they had officially been freed by the Emancipation Proclamation. The Emancipation Proclamation had become official two and a half years before, on January 1, 1863.  Slaves in Texas, however, remained enslaved due to the lack of Union troops to enforce the freeing of the slaves.

Need an Illusion module In wordpress donation Website

I hope all of you are fine.

I am making a donation website in WordPress.

There will be a charity account creation that has 4 different amounts in cents. Users will create their account and donate to that charity. It will be recurring based.

For charity creation, I am using woo commerce along with the WCFM marketplace plugin which allows us to use the stripe split payment and create a charity profile submission from the front end.

What I exactly need is the amount is in cents as the daily purpose and it will be monthly basis donation. (Like amount is 25 cents daily but a donation is a monthly basis so it becomes $7.50 which will be deducted when user donate on that charity). But my goal is to show illusion like donor is donating on a daily basis. It will be shown on the donor account.

this is the website http://tervisdesign.com/purecents/ which is currently under development.

what I have done right now. I have complete the charity profile system and donor account system.

For recurring, I am using woo commerce subscription plugin which allows me to set the monthly recurring.

Just stuck in creating the illusion.

Please anyone can help me out to achieve this task to show an illusion in donor account that he is paying on a daily basis but actually monthly donation is deducted from his card.

Let me know if you need further information from me.

Thanks…

dnd 5e – Does the illusion described in the spell mental prison extend to the space above the target creature?

The spell text reads:

you make the area immediately around the target’s space appear dangerous in some way. (XGtE, pg. 161)

And the spell’s 10d10 damage triggers when,

the target is moved out of the illusion…or reaches any part of its body through it.

It seems this can be interpreted to mean the illusion appears on all sides around the target and not necessarily above the target. Can a creature with immunity to restrained and a flying speed avoid the 10d10 damage by flying up and out of the illusion?

dnd 5e – Can I Minor Illusion create a 5ft box around myself to block a scrying sensor’s sight?

This might disrupt the opponent a little, but won’t completely keep you safe.

Firstly, I read the wording of Scrying a little differently to you. In my opinion, “within 10 feet” means “no more than 10 feet away, and potentially closer,” rather than the “exactly 10 feet away” you’re interpreting it as. There’s no indication that the caster can voluntarily move the sensor, but my interpretation as a GM would be that if cast targeting an individual, it appears no more than 10 feet away, but will automatically move to a position that gives an unobstructed view of the target (if one exists).

Your GM might rule that differently to the way I would, but there’s another problem. If this strategy works, it’s much more likely to work for actions you can do very quickly than for writing a long, detailed explanation.

According to the text for Minor Illusion,

If a creature uses its action to examine the sound or image, the creature can determine that it is an illusion with a successful Intelligence (Investigation) check against your spell save DC. If a creature discerns the illusion for what it is, the illusion becomes faint to the creature.

The enemy scrying you will know the illusion is likely to be an illusion, as they see it come into being; they likely know to examine it to see if they can pierce it; and it’ll probably only take a few rounds for their Investigation roll to beat your spell save DC. Once they do, it will become faint to them and they’ll be able to see through it to what you’re doing inside. Once they’ve cottoned onto the trick, they may start readying actions to examine your illusions the moment they come into being; you’ll only have a brief window, if any time at all, in which they can’t see you.

dnd 5e – Can I Minor Illusion a 5ft box around myself to write notes when I know I am being scryed on?

My party is being scryed on by an enemy. We are all low level and don’t have access to second level spells yet. Can I get out paper and quill, cast minor illusion around myself as a 5ft cube of hollow stone, and write down sensitive information. Then pass the folded up paper to a party member and cast the illusion around them so they can read it? My theory is that because the scrying sensor is always 10ft away from the target they would just see a block of stone.

From Scrying:

On a failed save, the spell creates an invisible sensor within 10 feet of the target. You can see and hear through the sensor as if you were there. The sensor moves with the target, remaining within 10 feet of it for the duration.

c++ – How can I draw filled triangles with the illusion of color?

So I have used the code of this website for drawing filled triangles. But I would like to improve my game by adding the illusion of color. Well sadly I made my game for the monochrome Nokia 5110 screen which can’t draw just one pixel but needs to draw lines. So I though about a concept like that: I could enter a float into my fill triangle function (0-1 = 0-100%) and if I for example enter 0.5 then it will only draw 50% of all the pixels. This would be possible by always leaving a small gap when drawing lines. (I don’t care if it starts glitching at for example 1 – 10 percent)


So it turns out that I am just way to dumb to create such an complicated filling method. Is this even possible? Thanks in advance!

Epilogue : You don’t really need to create this whole function. Just a little tip or link to an already existing method will help. But thanks if you decide to create it anyway :3

Postprocessing – Vorpx 3D illusion with the naked eye

Due to the questions asked here and here, I still couldn't find a topic that was discussing what this image from the VorpX website looks like in 3D with no bobble effect, holography or cross-eye effect ONLY with the naked eye:

VorpX VR picture.

Notice how the right tree compared to the left tree causes this strange bang effect. The right tree looks like it is only jumping out of the screen relative to the left scene. How was that done?

Just stare at the right edge of the pavilion next to the right tree (adjust your head so that it is centered between each eye) and the tree appears to pop out.

Focal length – what is the cause of the moon illusion? Does it refer to the focus of the eyes?

What is the cause of the moon illusion? Does it refer to the focus of the eyes?

1. Explanation

As shown in the figure, the blue line is the lens, w is the height of the object, x is the height of the image, v is the image distance, u is the object distance and f is the focal length. The red line is the light path.

We all know the relationship between u, v, f

1 / u + 1 / v = 1 / f

and so

f = uv / (v + u) (1)

Knowledge from similar triangles:

x / w = (v-f) / f = v / f-1

and so

x = w (v / f-1) (2)

Inserting (1) into (2)

x = w (v / f-1)
= w ((v + u) / u-1)
= wv / u (3)

According to equation (3), x increases when v and w are fixed, when u decreases.

When the observer observes the moon on the horizon, u is smaller than the actual distance from the moon to the observer due to the influence of mountains and trees. According to equation (3), x increases as u decreases. The viewer will feel that the moon on the horizon is larger and closer than the moon on the zenith. It appears that the moon is "enlarged".

  1. Calculate the "enlargement rate".

    Let K be the ratio of the image of the moon on the horizon to the image of the zenith moon. Let U be the actual distance of the moon. u is the actual focus distance after the eyes on the ground are affected by the trees.
    and so

    K = (wv / u) / (wv / U)
    = U / u

    and so

    K = 380000000 / u (4)

    The picture of (4) is:

Enter the image description here

From this picture you can intuitively see that the closer the eyes of the viewer focus, the greater the magnification of the moon. Of course, the focus distance is also changed arbitrarily and also influenced by factors such as the dispersion circle.

According to formula (4), it can be known that the moon is magnified 1.26667 times when the observer observes the moon at a distance of 380 million meters with an eye focused on 300 million meters.

  1. prophecy

    Watching the moon on a spaceship should not create the moon's illusion. Because the eyes are no longer affected by the landscape on the ground. If the future spaceship can be built very large, the moon illusion will appear when the moon is observed on such a spaceship. Watching the earth on the moon should have the illusion of the earth. Animals should also have the illusion of the moon.

4. Conclusion

I think the moon illusion is the result of observing the moon with a relatively short focal length. In other words, it is the result of observing the more distant moon with the eyes on the closer distance. I think that's the reason for the moon illusion.

Focus – let's see if my view of the moon illusion is correct

Let's see if my view of the moon illusion is correct:

Enter the image description here

The real cause of the moon illusion?

As shown in the figure, the blue line is the lens, w is the height of the object, x is the height of the image, v is the image distance, u is the object distance and f is the focal length. The red line is the light path.
The relationship between u, v, f is

1 / u + 1 / v = 1 / f

and so

f = uv / (v + u) (1)

The observer's eyes are constant, so v is fixed. The distance between the observer and the object is constant, so u is also fixed. As soon as v and u are fixed, it can be known from equation (1) that f is also fixed. If v is fixed and u decreases, f also decreases.

Knowledge from similar triangles:

x / w = (v-f) / f = v / f-1

and so

x = w (v / f-1) (2)

According to formula (2), x increases when v and w are fixed, when f decreases.

If the observer observes the moon on the horizon due to the influence of mountains and trees, f is smaller than when observing the moon at the zenith. According to formula (2) we can know that x increases as f decreases. The viewer will feel that the moon is larger and closer on the horizon than the moon at the zenith.

I think that's the reason for the moon illusion.

Simple calculation

If you look at nearby trees with your eyes:

u = 200 m (assuming 200 m from the tree)

v = 0.024 m (eyeball diameter, assumed image length)

w = 10 m (provided the tree is 10 m high)

f = uv / (v + u)
= 0.0239971 m

x = w (v / f-1)
= 0.0012 m = 1.2 mm (height of the tree picture)

When you look at the zenith moon (without the influence of trees on the ground) with your eyes:

u = 380000000 m (distance from the observer to the moon)

v = 0.024 m

w = 3476000 meters (diameter of the moon)

f = uv / (v + u) = A (we set this focal length to A)

x = w (v / f-1)
= 0.000219537 m = 0.219537 mm

If you observe the moon towards the horizon with the focal length of the observation tree:

f = 0.0239971 m

x = w (v / f-1)
= 420.067 m

The observation of the moon image on the zenith is 0.219537 mm, and the observation of the moon image on the horizon is 420.067 m, which shows a big difference between the two. So if you use a focal length less than A, the moon will be "enlarged".

Of course, the eyes do not generally observe the moon with a focal length of 0.0239971 m. Because the picture may not be clear. If the image of the moon is not clear at this focal length, the eyes adjust the focal length. Set a focal length that is clear for imaging. This focal length is less than A, but it is the focal length for clear imaging. Since the moon is far away, the depth of field of the moon imaging is very large. Therefore, there is a focal length that is smaller than A and can reproduce clearly. The moon illusion is therefore caused by a relatively short focal length. I think that's why the moon illusion.
