Poliigon–岩石三维模型 大小:41G

信息:
很少有资产能像岩石一样获得如此多的收益。阿奇维兹、环境、科幻星球——都被岩石包裹着。对于商人来说,就像螺丝刀一样,岩石对于3D艺术家来说也是如此。
但你可能也经历过相当多的坏石头——拉伸、缺乏细节、光线不均匀等等。
因此,我们花了几个月的时间对我们的照片扫描工作流程进行了重大投资,以创建一个可以正常工作的岩石集合。

我们是怎么做到的
每个人都知道图像扫描是王道。但是“好的”照片库和“优秀的”照片库之间有很大的区别。以下是我们如何让他们变得优秀的…

准确的愉悦
不再旋转模型来寻找“好的一面”。在测试了大多数已知的令人愉快的技术之后,我们决定结合高强度闪光、偏振、HDR光捕获和定制的光中和节点设置。它并不便宜,但却能产生完美的结果。

标准的
不再调整材料使它们匹配。通过颜色中和、反射消除和自动化处理管道,我们确保每个模型都与现实世界中的外观相匹配。

疯狂细节
享受500,000多边形网格和16K纹理带来的极致真实感。

通过加倍典型的照片覆盖和计算额外的密集网格,然后烘焙成法线,模型达到罕见的保真度。

最佳化的
我们知道岩石只是一个更大场景的一部分,所以我们创建了5级细节(LODs),最高可达16K纹理,因此您可以在实时游戏或近距离离线渲染中使用它。
Poliigon – Rock Models

Info:
Few assets get as much mileage as a rock. Archviz, environments, sci-fi planets – all encrusted with rock. Like a screwdriver to a tradesmen, a rock is to a 3D artist.
But you’ve probably also experienced your fair share of bad rocks – stretching, lack of detail, uneven lighting etc.
So we spent months making a significant investment into our photoscanning workflow to create a collection of rocks that just work.
Poliigon – Rock Models
How we did it
Everybody knows photoscanning is king. But there’s miles of difference between a ‘good’ photoscan, and an ‘excellent’ photoscan. Here’s how we made them excellent…

Accurate Delighting
No more rotating the model to find the “good side”. After testing most known delighting techniques, we decided on a combination of high-intensity flashes, polarization, HDR light captures and a bespoke light neutralizing node setup. It wasn’t cheap but it makes for a flawless result.

Standardized
No more tweaking materials to make them match. By colour neutralizing, reflection removal, and an automated processing pipeline – we ensured each model matches how it looks in the real world.

Insane Detail
Enjoy 500,000 poly meshes and 16K textures for ultimate realism.

By doubling the typical photo coverage and calculating extra dense meshes which are then baked into normals, the model reaches a rare fidelity.

Optimized
We know rocks are just one part of a bigger scene, so we created 5 levels of detail (LODs) with up to 16K textures, so you can use it in real-time gaming or upclose offline rendering.
