Triplanar

三面体

With the Triplanar node, up to six shaders can be projected from six different directions and also be superimposed. This can make unwrapping UV coordinates for complex objects unnecessary. 使用三平面节点，可以从六个不同的方向投射多达六个着色器，也可以叠加。这可以使复杂物体的紫外线坐标展开变得不必要

Quad mapping is a popular projection type for textures because materials can be assigned to just about any object shape. The distortion of the projected textures is kept to a minimum because a flat projection is made from all six cardinal points. The only disadvantage is the often visible hard edges where the projections from the different directions meet. The Triplanar node can reduce this effect by calculating soft transitions between the projections.

四边形贴图是一种流行的纹理投影类型，因为材质几乎可以分配给任何对象形状。投影纹理的失真保持在最小，因为一个平面投影是由所有六个基点。唯一的缺点是在不同方向的投影交汇处常常可见的硬边。三平面节点可以通过计算投影之间的软跃迁来减少这种影响。
