我无法调用glm :: rotate(mat4,int,vec3(x,y,z));上班。 VS 2010告诉我
Intellisense: no instance of function template "glm::gtc::matrix_transform::rotate" matches the argument
我正在使用glm-0.9.1
我已经看到了这个堆栈溢出问题,但解决方案仍然会触发intellisense错误:glm rotate usage in Opengl
我无法接受任何重载方法。我可能只是遗漏了一些明显的东西。
我试图在代码中显示旋转调用,它有点下降。
这里有一些代码:

我不太了解模板给你一个很好的答案,但我相信我对GLM的记忆是它对类型非常挑剔。
您可以尝试明确地将45
更改为45.f
,看看它是否接受了吗?我认为你需要有一致的参数(浮点矩阵,浮点数,浮点数)。我认为int会以某种方式混淆它。
答案 1 :(得分:1)
glm::rotate(Model, (glm::mediump_float)45, glm::vec3(1,0,0));
我发现由于glm::vec3
中使用的类型作为模板,此演员阵容有所帮助。
此功能定义为:
glm::detail::tmat4x4<glm::lowp_float> glm::rotate<glm::lowp_float> ( const glm::detail::tmat4x4<glm::lowp_float> &m, const glm::lowp_float &angle, const glm::detail::tvec3<glm::mediump_float> &axis)
因此,您必须在角度值中使用适当的类型。
答案 2 :(得分:-2)
我认为问题实际上是在“glm.h”文件中。老实说,我对解释原因的技术知识知之甚少,但是当我尝试修复此错误时,它起作用了。所以我只想把我的经验分享给有需要的人。
如您所知,我们定义自己的库文件应该(或需要)放在双引号 (" ") 而不是尖括号 (< >) 之间。
因此,当我右键单击 #include"glm.h"(转到文档“glm.h”)以查看发生的情况时,它会将我定向到该文件。在里面,我可以看到另外 3 行:
#include <glm/glm.hpp>
#include <glm/gtc/matrix_transform.hpp>
#include <glm/gtc/type_ptr.hpp>
然后我将 <> 更改为“”,正如我之前所说:
#include "glm/glm.hpp"
#include "glm/gtc/matrix_transform.hpp"
#include "glm/gtc/type_ptr.hpp"
我的 glm::rotate() 函数现在可以工作了!!!
