伙计们，理想情况下它应该产生相同的输出，但事实并非如此。我是计算机图形学的新手，已经学习一周了。如果我知道这里的错误是什么，真的会有帮助吗？如果这还不够，我真的很抱歉，我会回答更多问题。如果可以请帮忙
很难相信我当前的代码可能会由于这一行而生成一些合理的输出：
view = glm::translate(view, glm::vec3(0.0f, 0.0f, -3.0f));
// which combines matrix as follows: view * translationMatrixBasedOnVec(0,0,-3)
哪里
view
由 mat4 默认构造函数初始化 - 所有矩阵的分量均为 0。因此顶点着色器生成的任何顶点位置都是 (0, 0, 0, 0)。
如果要将相机定位在 (0,0,0) ，
viewglm::mat4 view(1.f)
