Sphere bounding box

WebJan 24, 2007 · So you can either calculate it on the fly when you need the bounding box (base on the sprite location, width, height). Or you can have the bounding box pre-calculated, stored with your object, and updated everytime you move your sprite or change size. To create a bounding sphere (well, a circle in 2D), you need to find the center of your sprite. WebJan 24, 2007 · To create a bounding sphere (well, a circle in 2D), you need to find the center of your sprite. Easiest center point calculation is (upper-left-x + (width/2), upper-left-y + …

WebComputing an object space bounding box for a sphere is straightforward. The implementation here uses the values of zmin and zmax provided by the user to tighten up the bound when less than an entire sphere is being rendered. However, it doesn’t do the extra work to compute a tighter bounding box when ϕmax is less than 3 π /2. WebFeb 1, 2024 · The sphere bounding box is used to remove the disjoint objects, and then particle swarm optimization is used to optimize the dimensions and improve the collision detection speed.
