Setting gravity for SceneKit ParticleEngine particles

由 我与影子孤独终老i 提交于 2021-02-11 12:47:28
问题 I'm just experimenting with SceneKit as a continuing migration through methods of 3D rendering. I have played with SceneKit and it is generally as advertised. One troublesome aspect (for me) is that while I can create ParticleEngines via the UI or code, I can't figure out how to set the gravitational field for particles created via code. The working code is here: https://github.com/rkwright/ParticleTest. Works with XCode 12.3 and iOS 15.3 Here is the function that sets up the ParticleEngine

Moving a 2D physics body on a parabolic path with initial impulse in unity

由 送分小仙女□ 提交于 2021-02-10 05:10:27
问题 What I have: A projectile in Unity 5 2D, affected by gravity, that I want to move from point A to point B with initial impulse on a parabolic path What I know: The 2D coordinates of a random starting position (A) The 2D coordinates of a random target position (B) The time (X) I want the body to reach the target position after What I want to know: The initial impulse (as in unity applyforce with forcemode impulse) that I have to apply to the body onetime in order for it to reach the desired

How do you properly implement gravity to a free floating space object and some sort of friction when thrusting in opposite direction

由 和自甴很熟 提交于 2021-02-02 03:50:26
问题 I am trying to program movement that is basically like Asteroids where once UP button is pressed you accelerate to a certain speed and then because in space you don't stop and can only slow down by thrusting in opposite direction. On top of that, I would like gravity to be pulling you towards the bottom of the screen. I have this accomplished for the most part but the issue I have is: When I turn around and thrust opposite direction, it doesn't slow down first going backwards before starting

刺激2019：从AWS和阿里云看云计算疯狂的一年

由 无人久伴 提交于 2021-01-31 19:27:03
云计算从业者有个不成文的条约：国外看AWS，国内看 阿里云 。 怎么个看法？AWS的 re:Invent大会 有6万多人参加， 阿里云 的杭州云栖大会有4万多人参加。这个比例竟与两家巨头的母公司市值出奇一致——亚马逊8千多亿，阿里巴巴5千多亿。 每到深秋入冬时节，全球顶级工程师都聚在拉斯维加斯和杭州进行一场朝圣之旅，汲取两位风向标大佬的思考和灵感。 如果说re:Invent是开发者的天堂，那云栖大会就是创业者的武林，无论是酷科技文化的天堂还是刀光剑影的武林，都为过去5年的云计算划上了一个完整的句号。 上云要趁早、云原生、容器、更大又更小的数据库、全自动DevOps、雾服务器、边缘计算……这些年我们早已被这些熟悉的字眼包围。 接下来马上迈入的2020年将开启下一个五年，两位A姓大佬又给我们带来了什么样的讯号？ 云计算技术下沉：芯片成兵家必争之地 云厂商对算力的需求是无止尽的，尽管服务器市场已经明显转向云厂商，但这阻挡不了云厂商自己搞芯片。毕竟，谁有更强的算力，就掌握了更多的主动权。 AWS在2019 re：Invent大会上推出了基于ARM架构的Graviton2高性能处理器芯片以及机器学习芯片Inferentia，前者比X86实例的性价比高出40%。Graviton一词来自gravity（引力），意味着芯片从过去的幕后走向前台，成为吸引云计算用户的关键作用力。虽有一代芯片发布在前

How to create a table of gravity models side by side, using the Gravity Package in r

由 谁说胖子不能爱 提交于 2021-01-28 00:55:54
问题 I would like to create a table like the tables from the stargazer Package. But using the Gravity Package for creating gravity models, this package isn´t supported by the stargazer package yet. Do you have an idea, how to create a similar table with 3-5 models side by side for better comparison? Output should look like this, just with gravity models from the gravity package in r: Desired Output Style: 回答1: Please provide an example of model object created by gravity package. Alternatively, I
