几何体着色器计算的线在摄影机移动时消失

我使用几何体着色器绘制顶点法线。除了当我移动相机时，一些线条部分消失之外，一切都如预期的那样显示出来。首先，我认为这是由于截锥体的大小，但我在场景中有比这个更大的其他对象，画得很好。

移动前

移动后

如果有人能给我任何关于如何消除这种线条消失的影响的建议，我会非常感激

下面是我的几何着色器的代码

#version 330 core

layout (triangles) in;
layout (line_strip, max_vertices = 6) out;
in Data{
    vec4 position;
    vec4 t_position;
    vec4 normal;
    vec2 texCoord;
    vec4 color;
    mat4 mvp;
    mat4 view;
    mat4 mv;
} received[];

out Data{
   vec4 color;
   vec2 uv;
   vec4 normal;
   vec2 texCoord;
   mat4 view;
} gdata;

const float MAGNITUDE = 1.5f;
void GenerateLine(int index) {
    const vec4 green = vec4(0.0f, 1.0f, 0.0f, 1.0f);
    const vec4 blue = vec4(0.0f, 0.0f, 1.0f, 1.0f);
    gl_Position = received[index].t_position;
    //gdata.color = received[index].color;
    gdata.color = green;
    EmitVertex();
    gl_Position = received[index].t_position + received[index].normal * MAGNITUDE;
    //gdata.color = received[index].color;
    gdata.color = blue;
    EmitVertex();
    EndPrimitive();
}
void main() {
    GenerateLine(0); // First vertex normal
    GenerateLine(1); // Second vertex normal
    GenerateLine(2); // Third vertex normal
}
