WebNov 3, 2024 · A simple way to visualize third angle projection is to place the object in the bottom of an imaginary bowl. Sliding the object up the right edge of the bowl reveals the right side view, sliding up the left edge of the bowl reveals the left side view, and so on. tolerance: The acceptable deviation of the actual value from a specified value. WebFor AABBs this is quite easy to determine due to the fact that they're aligned to the scene's axes: we check for each axis if the two object' edges on that axis overlap. So we check if the horizontal edges overlap, and if the vertical edges overlap of both objects. If both the horizontal and vertical edges overlap we have a collision.

"There are many methods for edge detection, but most of them can be grouped into two categories, search-based and zero-crossing based. The search-based methods detect edges by first computing a measure of edge strength, usually a first-order derivative expression such as the gradient magnitude, and then searching for local directional maxima of the gradient magnitude using a com… " - How do we detect edges of items in a drawing
