Bettering Simulation and Performance with an Developed Physics Solver

In mid-2015, Roblox unveiled a major upgrade to its physics engine: the Projected Gauss-Seidel (PGS) physics solver. For the first year, the new solver was optional and provided improved fidelity and greater performance compared to the previously used spring solver. In 2016, we added support for a diverse set of new physics constraints, incentivizing developers…

Roblox Physics: Constructing a Higher Sleep System

Let’s talk about “sleep” in a physics engine. The purpose of a sleep system is to stop doing work on bodies that aren’t moving, and start doing work when they will be. The challenge is picking the best heuristic for transitioning between these states. A common approach in other engines is to monitor a body’s…

三年的 Metal 旅程

我們在三年前把成像器換成了 Metal。 轉換過程非常地順利,Metal 在 iOS 的效能也很棒。 我們想花一點時間分享我們做這個決定的過程,還有執行之後的成果。(先在這裡講明,成果很棒喔!) 當初的反思大部分都還成立,不過 Metal 現在的表現越來越好了,我們想在轉換成 Metal 滿三年的這個時間重新和大家分享一下。 那就讓我們搭上時光機回到 2016 年 12 月,我們剛剛在 iOS 上推出早期的 Metal 成像器版本的時候吧。 為什麼要用 Metal? Apple 在 2014 年的全球開發者大會(WWDC)宣布 Metal 的時候,我第一個反應是完全不理它。 Metal 只能在尚未普及的最新硬體上使用,雖然 Apple 提到它可以解決 CPU 效能方面的問題,但是只幫到市場佔有率極小的使用者族群的話,效能最高和效能最低的裝置之間的差距將會拉得更大。 我們當時只有在 Apple 裝置上使用 OpenGL ES2,才剛開始在 Android 裝置上推出。 以下是兩年半過後 Metal 在我們使用者族群的市場佔有率: 這個比例讓 Metal 跟以前相比更加吸引人。 Metal 的確還是對最老舊的裝置沒有幫助,但是因為 GL 在 iOS 的市場不斷在縮小,和我們會為老舊與較新的裝置常常會給予不同內容,我們覺得花一點資源優化 Metal…
