GLM：函数取度数作为参数已弃用（WHEN使用RADIANS） [英] GLM: function taking degrees as a parameter is deprecated (WHEN USING RADIANS)

问题描述

目前使用VC ++ 11与SDL2，GLM和GLEW。这个问题源于GLM，当我试图做两件事情：创建一个旋转矩阵，创建透视相机矩阵（3D）。

Currently using VC++ 11 with SDL2, GLM, and GLEW. The issue is stemming from GLM when I attempt to do two things: Create a rotation matrix, create a perspective camera matrix (3D).

错误是：GLM：透视函数以度为参数已弃用
弧度（作为浮点）。它说我应该定义类似#define GLM_FORCE_RADIANS。这是真的有必要吗？

The error is: "GLM: perspective function taking degrees as a parameter is deprecated" despite the fact that I am passing radians (as floats) to both functions. It says I should define something like "#define GLM_FORCE_RADIANS." Is that really necessary?

我个人使用度数为一切，但OpenGL，所以必须转换来回（AI运动和什么不是）是一个痛苦，实际上导致CPU尖峰当我有很多NPC移动。

Personally I use degrees for everything, but OpenGL, so having to convert back and forth (for AI movement and what not) is a pain and actually causes a spike in CPU when I have many NPCs moving.

推荐答案

#define degreesToRadians(x) x*(3.141592f/180.0f)

静态部分应在编译时由编译器解析，任何程度的glm东西与那个宏，你做完了。也添加

the static part should be resolved at compile time by the compiler, just surround any degrees to glm stuff with that macro and you are done. Also add

#define GLM_FORCE_RADIANS

包含和glm标题之前，所以它将默认使用弧度而不是度

before including and glm headers, so that it will by default use radians instead of degrees
