History of the Allegorithmic

Allegorithmic历史 Official website.官网。 2003年成立的 allegorithmic(以下称 allegorithmic)是基于创始人 Sébastien Deguy 博士的数学论文，在图形产业应用程序化(Procedural)方式的技术开始的。 Founder: Doctor. Sébastien Deguy Allegorithmic 创始人 Sébastien Deguy 博士。是世界第一个把程序化贴图技术应用到游戏图形的人。 当时的电脑图形都是依赖于像素化图片的，所以不需要程序化技术或这种方式。 部分皮克斯等动画公司也只是使用Renderman，游戏产业几乎没有使用。 因为没有多少图形产业是需要高分辨率演算的。 特别是在图形市场，用程序化方式制作图片或 3D 贴图对美术来说是比较难的尝试，在这个时期 allegorithmic的贴图middleware诞生了。 程序化方式是指用数学计算储存 description 代码图片的信息，用GPU或者CPU演算生成图片，而不是用以前的像素化图片。 也就是说硬件性能的影响是非常大的。 当时高性能硬件没有大众化，玩家也是比较喜欢休闲3D游戏，而不是高品质3D游戏。 COPYRIGHT ALL RIGHT RESERVES PRO FXTM BY ©ALLEGORITHMIC. 现在的 Substance 的母体 ProFX 这个 middleware 上市时，只是用在高性能硬件的好莱坞电影产业的特效制作上 ，及其受限。 硬件功能中，特别是 GPU 的性能和显示器等视觉硬件技术极速发展，网络普及的时期， PC 游戏和网游产业也开始急速发展。 玩家想要更现实的3D图形品质，虽然游戏剧情也重要， 但开发者们对焦的还是分辨率和有现实感的视觉效果。 随着分辨率提高， 3D...
