引言
在现代游戏开发中，光照与阴影系统是构建逼真3D场景和实现沉浸式视觉体验的核心技术。随着Cocos2d-x从2D引擎向3D引擎的演进，以及Cocos Creator对3D功能的不断完善，开发者现在可以在Cocos引擎中创建具有真实感的光照效果和动态阴影。光照不仅决定了场景的视觉基调，还能引导玩家注意力、营造氛围、增强游戏的真实感。阴影则提供了物体间的空间关系信息，是深度感知和场景可信度的关键因素。本文将深入探讨Cocos2d-x 3D和Cocos Creator中的光照模型实现，从基础概念到实际应用，帮助开发者掌握这一核心技术。
一、技术背景
1.1 光照模型基础理论
1.1.1 Phong光照模型
Phong光照模型是最经典的局部光照模型之一，由环境光、漫反射光和镜面反射光三部分组成：
1.1.2 PBR（基于物理的渲染）
现代游戏引擎普遍采用PBR模型，更符合真实世界的物理规律：
-
金属工作流（Metallic-Roughness）
-
镜面反射工作流（Specular-Glossiness）
-
1.2 Cocos2d-x 3D光照架构
Cocos2d-x 3D通过以下组件实现光照系统：
1.3 Cocos Creator光照特性
Cocos Creator在Cocos2d-x基础上提供了更完善的可视化光照编辑：

9.2 性能优化技巧
// 动态光源LOD系统
void updateLightLOD(Light* light, const Vec3& cameraPos) {
float distance = cameraPos.distance(light->getPosition());
if (distance > light->getRange() * 0.5f) {
// 远距离：降低阴影质量或禁用阴影
if (light->isShadowEnabled()) {
light->setShadowMapSize(512); // 降低分辨率
}
} else if (distance > light->getRange() * 0.2f) {
// 中距离：中等质量
light->setShadowMapSize(1024);
} else {
// 近距离：最高质量
light->setShadowMapSize(2048);
}
}
// 分帧更新阴影
void distributeShadowUpdates(const std::vector<Light*>& lights) {
static int currentLightIndex = 0;
if (lights.empty()) return;
// 每帧只更新一个光源的阴影
lights[currentLightIndex]->setShadowUpdateEnabled(true);
currentLightIndex = (currentLightIndex + 1) % lights.size();
// 其他光源暂停阴影更新
for (int i = 0; i < lights.size(); ++i) {
if (i != currentLightIndex) {
lights[i]->setShadowUpdateEnabled(false);
}
}
