QUESTION

Why am I getting strange values for integer in this example of derived class (C++)

Asked 2021-Apr-16 at 05:25

I was given a task to write an example of derived class. But In my program, something strange is happening with the roll numbers.

Also, when this program is compiled in g++.

When I used char [] and gets() to store the strings and input values into them, it didn't allow me to enter the value for collname.

When I use string and cin, I get some strange values while asking for marks.(Check the attached image).

You just forget the [i] after rollno in the two lines like:

White Pixels In What Looks Like Antialiasing Glitch

Asked 2021-Jan-25 at 07:05

I see some white pixels around the border of the red shape in Firefox:

Here's a zoom of the area near the R.

What I expect

What I get

But the fragment shader code basically just checks some condition, writes a red pixel if true and writes information from the background image if false. There is no antialiasing implemented. So I wonder, where do those artefacts come from?

ANSWER

So AFAIK the issue is that you can't use texture lookups in conditionals or they'll break your varyings

From the GLSL ES 1.0 spec appendix A

6 Texture Accesses
Accessing mip-mapped textures within the body of a non-uniform conditional block gives an undefined value. A non-uniform conditional block is a block whose execution cannot be determined at compile time

And the GLSL ES 3.0 spec section 8.8

Some texture functions (non-“Lod” and non-“Grad” versions) may require implicit derivatives. Implicit derivatives are undefined within non-uniform control flow and for vertex texture fetches.

In other words, you need to move this line in your fs_warp shader

Install prepr

The prepair C++ library need these two libraries to compile:. The R package prepr solves the CGAL dependencies by shipping with a subset of the CGAL header. We also use rwinlib to provide GDAL on Windows in order to build this package from source. You will need the latest version of rtools in order to build the source code on Windows.
