i'm building a raycasting engine and i've done the 2d projection, with wall collisions, now shifting to 3d i'm not being able to render a proper 3d image, i'll throw my code below:

Im trying to write an Software Renderer using this tutorial series: https://www.youtube.com/watch?v=2U-4_vpw1lQ&list=PLEETnX-uPtBUbVOok816vTl1K9vV1GgH5&index=13

Explanation about the code
in this program I have defined three structures
one to represent a Point,one to represent rectangular block with 4 coordinates,one to represent overlap between pair of cells.
There is function(computeCellWidth) to dynamically compute width of cells according to a formula.
There are three rows ROW1,ROW2,ROW3 in which cells will reside.
This program will first ask for number of cells and this is numbers of cells per row.At first x,y coordinates for each cell is randomly generated.Then placeVertical() function will move cells to different rows which are spanning across two rows.Then there is a placeHorizontalGreedy() function which will remove overlap among cells by first finding overlaplength and then sorting them and removing the overlap between cells which has least overlap and this process will continue till either there will be no overlaps or overlap removal is not possible anymore.Here I would like to bring to the notice of everybody that cells will be moved towards the right of the grid to remove overlaps.In placeHorizontalGreedy() function I have used a variable p which will indicate number of overlaps after each iteration.for small number of cells testing for p to be zero works fine but not as I increase the numbers.Plus how can I make sure that overlaps exists but overlap removal is not possible anymore,so that I can stop the loop. Please help me out.
I am confused about what could be the problem in this algorithm:
With these parameters:
ine temp = {(Vector){10, 150}, (Vector){120, 40}, polygon->color};
drawaLine(monitor, &temp);
However, when I change the coordinates to 120, 20 it fails:
Line temp = {(Vector){10, 150}, (Vector){120, 20}, polygon->color};
drawaLine(monitor, &temp);
My code is:
int changed = 0;
int x = line->start.x;
int y = line->start.y;
int dx = (line->end.x - line->start.x);
int dy = (line->end.y - line->start.y);
dx = (dx < 0) ? -dx : dx;
dy = (dy < 0) ? -dy : dy;
int signx;
int signy;
if ((line->end.x - line->start.x) == 0) {
signx = 0;
} else {
int tempsignx = (line->end.x - line->start.x);
signx = (tempsignx < 0) ? -1 : 1;
}
if ((line->end.y - line->start.y) == 0) {
signy = 0;
} else {
int tempsingy = (line->end.y - line->start.y);
signy = (tempsingy < 0) ? -1 : 1;
}
//swap values
if (dy > dx) {
int temp = dy;
dy = dx;
dx = temp;
changed = 1; //changed = true
}
int e = 2 * dy - dx;
for (int i = 1; i <= dx; i++) {
Vector temp = {x, y};
drawPixel(monitor, temp, line->color);
while (e >= 0) {
if (changed) {
x = x + signx;
} else {
y = y + signy;
e = e - 2 * dx;
}
}
if (changed) {
y += signy;
} else {
x += signx;
e = e + 2 * dy;
}
Vector x2y2 = {line->end.x, line->end.y};
drawPixel(monitor, x2y2, line->color);
}
}
My program that I built using Unity3D sporadically freezes, and this action freezes my computer. I'm unable to pinpoint the root cause. I had placed logs all over my project, but the game failed to freeze.
Has any Unity3D developer experience their apps sporadically freeze in the manner in which I am describing? Does anyone have any ideas or suggestions?

-----------
I believe I have narrowed the freezing down. Simulated testing results is leading me to believe that my problem is inside the OnGUI() method. I have commented that method out all together, and my app is operating smoothly. I'll figure this out, unless someone beats me to the root cause and solution.
I solved it...
My initial suspicions were correct: the problem did lie within the OnGUI() method. I moved the following source code to the Start() method. It made sense, since I'm only building a transparent background texture once.:
Texture2D texture = new Texture2D(32, 32, TextureFormat.ARGB32, false);
for(int i = 0; i < 32; i++)
{
for(int j = 0; j < 32; j++)
{
texture.SetPixel(i, j, new Color(0.0f, 0.0f, 0.0f, 0.25f));
}
}
texture.Apply();
