Watching my son play GTA5 and (being a nerd) I wondered about the physics engine of the game. How far from reality is it? Is gravity half as strong as usual? Are car impacts dampened 60%, 70%?
Anyone know?

Hello to everyone in the game development and graphics rendering community! I've encountered a specific issue, a 'BVH black hole', within a SAH-constructed BVH tree. This phenomenon refers to a very specific, small spot where an excessive number of BVH Nodes or triangles within these nodes accumulate, causing a significant drop in frame rate during applications such as ray casting. Has anyone else experienced a similar situation or have any potential solutions or advice? All input is greatly appreciated. Let's get a discussion started! #BVH #3DRendering #PhysicsEngine #GameDev #PerformanceIssues #RayCasting

Well... I have no bloody clue what I did wrong .-.

So I was going to ditch the idea of a #physicsengine engine for #virgil and using either #box2c or physac, box2c is still in development and physac is not super accurate so in classic Alex fashion... Fuck it lets #reinventthewheel again!

I need to stop the mentality of 'it must perform perfectly' when I'm not even at version 1.0, yes 1.0 will release with bugs and slower performance but I can't push it off forever, think it's time to set a goal, version 1.0 in 1-2 months.
