WebMay 17, 2016 · Generally edge detection boils down to detect areas of the image with high gradient value. In our case we can crudely see the gradient as the derivative of the image function, therefore the magnitude of the gradient gives you an information on how much your image changes locally (in regards of neighbouring pixels/texels). WebTry changing the graphics style (edges to shading with edges), and see if you can snap to an edge then. I find that my models don't always render correctly and this seems to help. After you get your leader on the edge, you can put it back to the display style you want. Shading with edges didn't work, but wireframe did. small zen water fountain

"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.
