创建统一的GLSL数组? [英] Creating a GLSL Arrays of Uniforms?

问题描述

我想离开OpenGL的灯，自己做. 我希望我的着色器允许可变数量的灯光.

I would like to leave OpenGL's lights and make my own. I would like my shaders to allow for a variable number of lights.

我们可以在GLSL着色器中声明一个统一数组吗? 如果是这样，我们将如何设置这些制服的值?

Can we declare an array of uniforms in GLSL shaders? If so, how would we set the values of those uniforms?

推荐答案

是可以的.您声明的统一数组类似于在C中的方式，例如

Yes this is possible. You declare uniform arrays similar to how you'd do it in C, e.g.

uniform float v[10];

然后您可以使用glUniform{1,2,3,4}{f,i}v

GLfloat v[10] = {...};
glUniform1fv(glGetUniformLocation(program, "v"), 10, v);
