Question

我正在为openGl编写一个顶点着色器。这是我的代码：

#version 150

in vec4 vPosition;
in vec3 vNormal;

out vec3 fN;
out vec3 fE;
out vec3 fL;

uniform mat4 model_matrix;
uniform mat4 view_matrix;
uniform mat4 proj_matrix;

uniform vec4 lightPos;

void main()
{
    vec3 pos = (view_matrix * model_matrix * vPosition).xyz;
    vec3 lightPosInCam = (view_matrix * lightPos).xyz;

    fN = normalize(view_matrix * model_matrix * vec4(vNormal,1.0)).xyz;
    fE = normalize(vec3(0,0,0) - pos);
    fL = normalize(lightPosInCam.xyz - pos);

    gl_Position = proj_matrix*view_matrix*model_matrix*vPosition;
}

然而，当我运行我的程序时，似乎错误说我的}之后有一些nonASCII字符，因为在控制台打印中：

#version 150

in vec4 vPosition;
in vec3 vNormal;

out vec3 fN;
out vec3 fE;
out vec3 fL;

uniform mat4 model_matrix;
uniform mat4 view_matrix;
uniform mat4 proj_matrix;

uniform vec4 lightPos;

void main()
{
        vec3 pos = (view_matrix * model_matrix * vPosition).xyz;
        vec3 lightPosInCam = (view_matrix * lightPos).xyz;

        fN = normalize(view_matrix * model_matrix * vec4(vNormal,1.0)).xyz;
        fE = normalize(vec3(0,0,0) - pos);
        fL = normalize(lightPosInCam.xyz - pos);

        gl_Position = proj_matrix*view_matrix*model_matrix*vPosition;

然而，当我运行我的程序时，似乎错误说我的}之后有一些nonASCII字符，因为在控制台打印中：

这是当使用零字节（NUL）未正确终止到OpenGL的着色器源字符串和/或传递的缓冲区长度与源字符串的长度不匹配时遇到的典型错误。 / p>

解决方案：如果您没有显式传递长度（即为length参数传递NULL），请确保源字符串正确地为零终止。否则，请确保长度与源字符串缓冲区的长度正确匹配。

GLSL错误：非法的非ASCII字符
