将一组结构体传递到OpenGL es2.0着色器中

I want to implement some kind of lighting. And i'm making a struct, that contains light sourse properties in vertex shader:

我想实现一些照明。我正在制作一个结构体，它包含顶点着色器中的光源属性:

struct Light
{
    vec4 color;
    vec4 pos;
    ...
};

In my app i want to have several light sources. So i put:

在我的应用中，我想要几个光源。所以我把:

uniform Light[10];

How can i then load these uniforms from the app ? Is it a good approach or better to have:

我该如何从应用中加载这些制服呢?是好方法还是更好的方法:

uniform vec4 LightColor[10];
uniform vec4 LightPos[10];
...

I think you can't pass structures to OpenGL ES shaders. Please check this SO discussion that seems to confirm it:

我认为你不能将结构传递给OpenGL ES材质。请检查，所以讨论似乎证实:

Passing own struct into opengl es 2.0 shader

将自己的结构体传递给opengl es 2.0着色器

I think it's safer to use your second proposal based on the arrays of vec4 uniforms.

我认为你的第二个建议是基于vec4制服的阵列比较安全。
