Rendering datatypes registered on the VM: Vector3, Vector2, CFrame, Color3, Color4 constructors and bridging helpers.
Takes a BasePart or Vector3 and converts their 3D position to a 2D position on the screen. Returns the Vector2 and a boolean indicating if the 3D object is on the screen.
worldtoscreen| target | BasePart | Vector3 | The object or position to project. |
Takes a BasePart or Vector3, and returns a bool indicating if the 3D position is visible on the screen.
isonscreen| target | BasePart | Vector3 | The object or position to check. |
Projects an array of Vector3 in World space to Screen-space Vector2 objects. The projected points, with the boolean indicated if the point was within the bounds of the screen or not.
| points | { Vector3 } | The points to project. |
Computes the 2D convex hull of a point cloud using monotone chain (Andrew's algorithm) at O(n log n). The returned vertices are ordered counter-clockwise and contain no duplicates of the starting point at the end, so the result can be fed directly into immediate.convex_poly_filled. Input with fewer than three points is returned as-is.
| points | { Vector2 } | The point cloud to wrap. |
Computes the 3D convex hull of a point cloud (incremental Quickhull-style algorithm). Returns a table { vertices = { Vector3 }, faces = { { number, number, number } } } where each face is a triple of 1-based indices into vertices. Returns nil when the input has fewer than four points or is degenerate (all coplanar).
| points | { Vector3 } | The point cloud to wrap. |
Returns the size of the Roblox (and thus Overlay) window, doesn't include any decorations (like top bar of the window)
