uniform | Uniform distribution

Sounds like you use a perspective projection, and the formula you use in steps 1 and 2 won't work because VP * vec4 will in the general case result in a vec4(x,y,z,w) with the w value != 1, and adding a vec4(a,b,0,0) to that will just get you vec3( (x+a)/w, (y+b)/w, z) after the perspective divide, while you seem to want vec3(x/w + a, y/w +b, z). So the correct approach is to scale a and b by w and add that before the divde: vec4(x+a*w, y+b*w, z, w).

Note that when you move your camera closer to the geometry, the effective w value will approach towards zero, so (x+a)/w will be a greater than x/w + a, resulting in your geometry getting bigger.

You requested SAS to name the count n, the sum sum and the mean mean. It can only do that for one variable.

This is the syntax to ask SAS to use different names for the statistics of each variable:

The uniforms materialAmbient, ambientLight and specularLight are not "used" in the shader program. They are not required to calculate the output outColor (Actually materialAmbient are ambientLight use to calculate effectiveAmbient. effectiveAmbient, however is not used).
The compiler and linker optimize the program and removes unnecessary calculations and unnecessary variables. Therefore this variables become no active program resource and you cannot get the resource index (uniform location) for this variables.

you start your loop by defining a running variable 'i'. But all over the loop, you redefine it to be other integers and unrelated objects. Such as in line 83, line 155, and others. It's difficult to understand your intentions from the question. but if I understand correctly, the problem can be solved by changing every 'i' in the loop to a differently named temporary variable. A simpler solution would be to change the 'i' variable at the beginning of the for loop to smth else. I suggest you adopt a habit of using variable names that have meaning and not just single or double letters.

As far as I can tell, boundary specifies a spot to be a split between two bins. The rest of bins are set according to the number of bins or supplied break points. If the supplied boundary is outside the range of the data, some clever shifting is done according to the documentation. Maybe with the following examples it becomes clear what boundary does.

if you set limits for the x axis, you can circumvent the issue, although not a very elegant solution.

The Uniformgrid is just a panel. She has no means of marking boundaries. In each cell, you need to place a Border with its own borders. And in the Content Border (where necessary) place the output of the required element.

One example: Draw samurai sudoku grid on WPF

In your code example,

you are trying to get hessian of f(x)(model outputs) w.r.t. x(inputs) and f is linear (the model is linear).

Hessian of f(x) w.r.t. x should actually be a zero tensor, but tf.hessians can't handle that properly, resulting the error. Adding an additional layer with non-linear activation will eliminate the error.

Codes examples:

Using tf.hessians to get hessian:

In short - base C does not have support for this without macro trickery or libraries

If you are open to the two - you could use something homegrown like this:

The interface variabel Position is not used in the fragment shader. So the uniform variable u_ModelViewMatrix is not required. This uniform is "optimized out" by the linker and does not become an active program resource. Therefor you'll not get a uniform location for "u_ModelViewMatrix".
