使用 Emscripten 编译 GLUT

Question

我正在尝试编译以下代码： http://pastebin.com/024Ew4fK

我正在使用以下指令： -s LEGACY_GL_EMULATION=1 -lglut -lGLU -lGL

我收到以下警告：

warning: unresolved symbol: glPointSize
warning: unresolved symbol: glutSolidSphere
warning: unresolved symbol: glutWireSphere

这些是错误：

WARNING: using emscripten GL immediate mode emulation. This is very limited in what it supports

missing function: glPointSize

为什么说缺少glPointSize？

Answer 1

以下是 Emscripten 支持的 Glut 功能： https://github.com/kripken/emscripten/blob/master/src/library_glut.js

为了画一些东西，例如球体，Kripken 建议在某处寻找一个用 C 编写的函数，它可以自己完成，然后将该函数移植到我的程序中。
