Question

我正在尝试在Openscad中使用Bresenham的算法。我一点一点地把事情弄得一团糟，看看事情出了什么问题。查看Openscad的输出，我发现所提供的值的cos值不正确。以下是Openscad显示的值和cos（值）列表。

ECHO: 0.628319, 0.99994
ECHO: 1.25664, 0.999759
ECHO: 1.88496, 0.999459
ECHO: 2.51327, 0.999038
ECHO: 3.14159, 0.998497
ECHO: 3.76991, 0.997836
ECHO: 4.39823, 0.997055
ECHO: 5.02655, 0.996154
ECHO: 5.65487, 0.995133
ECHO: 6.28319, 0.993993

这是由代码生成的：

spots = 10;
difference(){
cylinder(r=50, h=10, center=true);
translate ([0,0,-10])cylinder(r=5, h=20);
for ( z = [1:10]) {
    assign (step = z/spots)
    assign (step2 = (2 * PI * step))
    echo (step2, cos(abs(step2)));
        }
             }

Answer 1

openscad中的

cos（）需要度，请尝试：

//assign (step2 = (2 * PI * step))
assign(step2 = 360*step)

在OpenScad中没有获得正确的cos值
