css div gradient shadow/border
You can fake one, using background gradient and a box-shadow, as well as a css pseudo element to mask the border. Note that if you change the background color of the surrounding content you have to change every instance of #444 .outer { box-sizing: border-box; padding: 25px; height: 200px; width:...
Using shell command output within VI editor
The :r! command always works 'likewise', so it will not be able to insert any text inside a given line. You can assign the command's results into a 'register' (vim's places to hold characters yanked, cut, etc) using: :let @a=system("your_command") and then place the contents of the register (your passed)...

Android “elevation” not showing a shadow
android,shadow,android-elevation
I've been playing around with shadows on Lollipop for a bit and this is what I've found: It appears that a parent ViewGroup's bounds cutoff the shadow of its children for some reason; and shadows set with android:elevation are cutoff by the View's bounds, not the bounds extended through the...
CGContextSetShadowWithColor puts shadows on top of the text casting the shadow
When calling to CGContextSetTextDrawingMode, set the drawing mode to kCGTextFill. To my understanding, the shadow you see is casted by the stroke of the text.
SVG - Inset and drop shadow at the same time
It depends on exactly what you want to do (the order matters), but you can e.g combine the two filters into one, like this: <filter id="inset-and-drop-shadow" primitiveUnits="objectBoundingBox" x="0%" y="0%"> <feOffset dx="0.01" dy="0.02" /> <feGaussianBlur stdDeviation="0.01" result="offset-blur" /> <feComposite operator="out" in="SourceGraphic" in2="offset-blur" result="inverse" /> <feFlood flood-color="black" flood-opacity="1" result="color" /> <feComposite operator="in"...

Shadow Map: whole mesh is in shadow, there is no light where it should be according to depth map
c++,opengl,glsl,shadow,shadow-mapping
Disable texture comparison for one thing. That's only valid when used with sampler2DShadow and you clearly are not using that in your code because your texture coordinates are 2D. This means replacing the following code: m_glFunctions->glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_COMPARE_FUNC, GL_LEQUAL); m_glFunctions->glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_COMPARE_MODE, GL_COMPARE_R_TO_TEXTURE); With this instead: m_glFunctions->glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_COMPARE_MODE, GL_NONE); Likewise, using GL_LINEAR...
UIButton shadow on all 4 sides

Since you offset the shadow by {4, 4} the shadow appears on the bottom-right side of the button. You could set a zero offset : myButton.layer.shadowOffset = CGSizeZero and by tweaking the shadowRadius you might achieve what you want. Here is how a shadow is built: (1st row) start from...
Lollipop: Had trouble showing a shadow under the overflow menu
So it turns out that android:hardwareAccelerated option needs to be true if shadows are to be rendered in Lollipop devices. Note that setting the flag isn't necessary as it's the default option for 4.0 devices (API Level 14) and higher. It's available on Android 3.X but is disabled by default....

Adding shadow to my text?
It is possible, but I guess the result is not what you expect. With -webkit-background-clip: text; you actually cut put a piece of the background in the shape of your text and with color:transparent you make the text itself invisible. So what you see here is actually the background. That...

How it is possible to get rid of spurious artifacts of Shadow Mapping?
javascript,webgl,shader,shadow
It looks like your shadow map is covering only a fraction of the scene, and is being tiled (repeated) to cover the rest. Change the wrapping mode for the shadow map to GL_CLAMP_TO_BORDER: glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_BORDER); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_BORDER); And set your border color to 1.0f or 0.0f, depending on...

shadowRadius doesn't blur the shadow
You probably want a smaller radius (like [1; 3]). Then on iOS you also need to specify the number of sample using shadowSampleCount (because the default is only 1 sample on iOS which implies no blur). Beware that increasing the number of samples will improve the quality but it has...
Stripped shadows on collada objects
javascript,three.js,shadow,stripes,directional-light
You are getting self-shadowing because the rays of the directional light are exactly parallel to some of the faces of your geometry. Move the directional light to a slightly different location. For example, directionalLight.position.set( 250, 500, 200 ); Usually, light.shadowBias is used to remedy self-shadowing problems, but it is not...
GLSL soft planar shadows: matrix transformation
opengl,matrix,glsl,shadow,affinetransform
Helpful community members of ##OpenGL on Freenode pointed out my error. As the projection matrix MATRIX does not produce an affine transformation, I needed to divide the distance calculation by point.w. This yields the correct distance between LIGHT.xyz and point.xyz. In short, if you're working with a projection matrix like...
Spotlight with shadows becomes square-like
c++,opengl,graphics,shader,shadow
This is intended. Since your shadowmap covers a pyramid-like region in space, your spotlight's cone can be occluded by it. This is happening because where you render something that is outside of the shadow camera's view, it will be considered unlitten. Therefore the shadow camera's view pyramid will be visible....
