I created this piece of Go code that renders a shaded triangle using a Barycentric algorithm
type Vertex struct {
x int16
y int16
r uint8
g uint8
b uint8
}
...
func (gpu *GPU) ShadedTriangle(v1, v2, v3 *Vertex) {
// Area of the parallelogram formed by edge vectors

the goal is to draw a cylinder and rotate it by -30° around the y-axis (i.e., towards me). This should be done as large and performant as possible. But the drawing should look reasonable, otherwise I can stay with MS Paint :D
My current problem is that I can't increment small enough. The drawing ...
I am learning to write more modern C++, since my C++ is from the 1990s (I'm a C# programmer). I need to get used to the STL algorithms and such. So I tried some kata, summing up numbers in a given range that are divisible by 3 or 5, using new C++11/14/17 stuff.
I know that it can be solved mathem...
I'm building a drag and drop sortable list in Javascript. This is what I have so far. Is this a good way to solve the problem? How can I improve my code?
<div id="list">
<ul>
<li data-value="Bananas" draggable="true">Bananas</li>
<li data-value="Keys" draggable="true">Keys</li>...
In C++ using input stream,
while(is >> x)
returns false when the stream cannot read more, but
if(is>>x)
does not compile. The compiler seems to interpret the condition
(is>>x)
differently for while() and if(). Why?
I am currently working on a custom TabBar component for my expo project using React Navigation V6. However, the example code that I used on the React Navigation docs to add in a custom tab bar shows an ugly nested ternary function inside the const label variable.
I have created a solution that re...
My program is written in python and I have tested it with small numbers like 21 and 35, but i tried running it with 600851475143 but it is taking forever to spit out my answer.
Anyways, my code is as follows:
def prime(number):
prime_factors = []
for num in range(1, number):
if nu...
