我正在处理隐藏在源代码中的着色器的项目。我收到此错误(在运行时):着色器编译错误
Error compiling vertex shader:
Full VS shader source:
//precision highp float;
uniform vec2 uEyeToSourceUVScale;
uniform vec2 uEyeToSourceUVOffset;

vPosition = aPosition;
vTexCoordR = aTanEyeAnglesR * uEyeToSourceUVScale + uEyeToSourceUVOffset;
vTexCoordG = aTanEyeAnglesG * uEyeToSourceUVScale + uEyeToSourceUVOffset;

vTexCoordB.y = 1.0 - vTexCoordB.y;
gl_Position = vec4(aPosition.xy, 0, 1);
}
Shader compilation failed.
我不知道如何处理解决这个问题(没有着色器经验);然而,我知道着色器代码与C++代码类似,从这个意义上来说,这看起来非常直截了当(除非我错过了某些东西)。
这个着色器代码有什么明显的错误吗?
您在日志中得到的错误消息是什么? –
@Nicol:如何检查日志? – George
