很抱歉,我作为一个AI语言模型,无法为你制作PPT,但我可以提供一些C语言光栅化画圆画直线的代码供你参考:
画直线:
```c
void drawLine(int x1, int y1, int x2, int y2) {
int dx = x2 - x1;
int dy = y2 - y1;
int steps = abs(dx) > abs(dy) ? abs(dx) : abs(dy);
float xInc = dx / (float) steps;
float yInc = dy / (float) steps;
float x = x1, y = y1;
for(int i = 0; i <= steps; i++) {
putPixel(round(x), round(y));
x += xInc;
y += yInc;
}
}
```
画圆:
```c
void drawCircle(int xc, int yc, int r) {
int x = 0, y = r;
int p = 3 - 2 * r;
while(x <= y) {
putPixel(xc + x, yc + y);
putPixel(xc - x, yc + y);
putPixel(xc + x, yc - y);
putPixel(xc - x, yc - y);
putPixel(xc + y, yc + x);
putPixel(xc - y, yc + x);
putPixel(xc + y, yc - x);
putPixel(xc - y, yc - x);
if(p < 0) {
p = p + 4 * x + 6;
} else {
p = p + 4 * (x - y) + 10;
y--;
}
x++;
}
}
```
其中,putPixel函数表示绘制像素点的函数,可根据具体的绘图环境进行实现。
