问题描述
我使用什么函数/数学来绘制 3d 表面?例如，我如何生成 z = sin(x+y)?点是如何计算和绘制的?我找不到任何示例.
What functions/math do I use to draw a 3d surface? For example, how do I generate z = sin(x+y)? How are the points calculated and drawn? I couldn't find any examples.
推荐答案

像这样的东西包含顶点.如果一个顶点由 [x,y,z] 组成，您可以通过循环遍历所有顶点来在那里应用您的函数.
Something like this contains vertices. If a vertex consists of [x,y,z] you can apply your function there by looping through all the vertices.
