为什么我得到空的 Asymptote 输出和空的错误文件？

我正在尝试复制这张图片

显示在这个答案到这个问题答案中提供的代码是：

% pdflatex --shell-escape impsurfsmooth.tex

当我执行时pdflatex --shell-escape impsurfsmooth.tex，我没有得到答案中显示的输出，而只是图形和子图标题。输出的相关部分是：

Asymptote 产生两个错误文件，trial3-ellipsoid_errors.txt和trial3-hyperboliccylinder_errors.txt，但它们都是空的。

在中impsurfsmooth.log有以下内容：

\openout3 = `impsurfsmooth-temp.asy'.

runsystem(cp impsurfsmooth-temp.asy impsurfsmooth-ellipsoid.asy)...executed.

Attempting to run asy on impsurfsmooth-ellipsoid.asy

! LaTeX Error: File `impsurfsmooth-ellipsoid' not found.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

I could not locate the file with any of these extensions:
.pdf,.png,.jpg,.mps,.jpeg,.jbig2,.jb2,.PDF,.PNG,.JPG,.JPEG,.JBIG2,.JB2,.eps
Try typing  <return>  to proceed.
If that doesn't work, type  X <return>  to quit.

有一个类似的部分抱怨impsurfsmooth-hyperboliccylinder未找到该文件。

我在 TeXShop 中尝试了同样的操作，结果相同。我做错了什么？（我在 macOS 10.14.6 上运行 MacTeX 2019（完全最新）。）

编辑：我按照@Marijn的建议尝试直接在文件上运行 Asymptote。我从上面的示例中提取了以下内容：

settings.outformat="png";
settings.render=8;
import graph3;
import smoothcontour3;

pen bpen = rgb(0.75, 0.7, 0.1);
material m = material(diffusepen=0.7bpen, ambientpen=bpen, emissivepen=0.3*bpen,
                      specularpen=0.999white, shininess=1.0);   

size(200,0);
currentprojection = orthographic(9,10,4);

// ellipsoid
real f(real x, real y, real z) {
  return (x^2)/(2^2) + (y^2)/(3^2) + (z^2)/(2^2) - 1;
}

draw(implicitsurface(f, (-3,-3,-3), (3,3,3), overlapedges=true), surfacepen=m);

xaxis3(Label("$x$",1),-4,4,red);
yaxis3(Label("$y$",1),-4,4,red);
zaxis3(Label("$z$",1),-4,4,red);

使用 through 运行此命令asy -vv trial4.asy似乎不会产生任何错误消息，但也不会产生任何输出。输出的最后几行是：

没有生成任何文件 - 甚至没有 trial4_.aux 或 trial4_.log。运行 with-vvv不会给出任何线索（至少对我来说没有）。

编辑2：根据@Willie Wong 的建议，我改为settings.render=0;，生成了此栅格化图像：
