不必要的vec4()
vec3()
仅用于调试问题。

#version 330

in vec3 toLightVector;
in vec3 toCameraVector;
in vec3 visibility;
out vec4 out_Color;

float nDotl = dot(unitNormal, unitLightVector);
float brightness = max(nDotl, 0.2);
vec3 diffuse = brightness * lightColor;
vec3 unitVectorCameraVector = normalize(toCameraVector);
vec3 lightDirection = -unitLightVector;
vec3 reflectedLightDirection = reflect(lightDirection, unitNormal);
float specularFactor = dot(reflectedLightDirection, unitVectorCameraVector);
specularFactor = max(specularFactor, 0.0);
float dampedFactor = pow(specularFactor, shineDamper);
vec3 finalSpecular = dampedFactor * reflectivity *lightColor;
out_Color = vec4(diffuse, 1.0) * texture(textureSampler, pass_textureCoords) + vec4(finalSpecular, 1.0);
out_Color = mix(vec4(skyColor, 1.0), vec4(out_Color), visibility);
}
答案 0 :(得分:3)
问题是您将vec3
用作mix()
的第三个参数。这是不正确的,因为它只能是与其他参数的类型相同的类型:vec4()
或使用原始类型。
