Splines: Add working state from a couple of months ago (pre FP) Basically a port of my C++ spline library wrapped with a component + editor tool. Still requires some API and Editor UX cleanup. https://files.facepunch.com/lolleko/1b0911b1/sbox-dev_0KaDTZAF7l.mp4 Nav Basic: Reduce rotation on test slope to account for floating point inaccuracies Fix obsoletes Add roughness test scene, Compares if IBL GGX Filter matches reference Update Roughness_test Use WorldTransform/LocalTransform First pass on spline model deformation https://files.facepunch.com/lolleko/1b1611b1/sbox-dev_pXP1R0vFzj.mp4 https://files.facepunch.com/lolleko/1b1611b1/sbox-dev_1SBGUutgNa.png Remove stackalloc (it's not whitelisted) Fix duplicating a spline point with shift not copying roll & scale Use sceneobjects for spline model instances instead of Graphics.Draw Deform spline model bounds to ensure accurate frustum culling https://files.facepunch.com/lolleko/1b1611b1/sbox-dev_FuFEWnL2FA.png https://files.facepunch.com/lolleko/1b1611b1/sbox-dev_xrWVBJicsC.png PoC spline collisions Currently just super hacky static mesh/model collision https://files.facepunch.com/lolleko/1b1711b1/sbox-dev_03QtKgtfYW.mp4 Update trails scene Hull based spline collisions Allows proper physics simulation of the spline models.
