osgVolume.VolumeSettings
是一个用于定义体积渲染设置的类,它由一组参数组成,可以用于调整渲染体积的外观和行为。这些参数包括颜色、透明度、光照、边缘模糊和渲染模式等。
以下是osgVolume.VolumeSettings
类支持的参数列表:
osg::Vec4
类型的颜色向量。osgVolume::INTERPOLATE_LINEAR
。可设置为osgVolume::INTERPOLATE_NEAREST
或osgVolume::INTERPOLATE_LINEAR
。osgVolume::RAY_TRACED
。可设置为osgVolume::RAY_TRACED
或osgVolume::SLICE_PLANES
。以下代码示例演示了如何使用osgVolume.VolumeSettings
类调整体积渲染的外观和行为:
osg::ref_ptr<osgVolume::VolumeSettings> settings = new osgVolume::VolumeSettings;
settings->color = osg::Vec4(0.5f, 0.5f, 1.0f, 0.8f);
settings->alpha = 0.5f;
settings->ambient = 0.1f;
settings->diffuse = 0.6f;
settings->specular = 0.3f;
settings->shininess = 10.0f;
settings->edgeBlur = 0.1f;
settings->interpolate = osgVolume::INTERPOLATE_LINEAR;
settings->renderingMode = osgVolume::SLICE_PLANES;
