为什么着色器编译错误与属性 int (Android opengl es2)
why shader compile error with attribute int (Android opengl es2)
为什么带有int属性的着色器编译错误？ (Android opengl es2)
attribute vec4 a_Position;
attribute vec2 a_TexCoord;
attribute int a_fckLen; ///--error compile
attribute float a_fckLen; //--compile ok
void main()
{
gl_Position = u_Matrix * a_Position;
}
但是float编译OK
来自 GLSL ES 1.00（GL ES 2 使用的）规范：
4.3.3 Attribute
...
The attribute qualifier can be used only with the data types float, vec2, vec3, vec4, mat2, mat3, and
mat4. Attribute variables cannot be declared as arrays or structures.
