Collision detection? o.o

Recommended Posts

Help... Sorry if I come across as a n00b... but my question is... What is vertex-to-face collision detection? How is it different that a bounding box method of collision detection? And how is it implemented? Thank you...

three vertices ("corners") make up one face... several faces make up triangles, polygons and whatnot.. :)

I'd recommend reading the red book of opengl... it contains lot of useful stuff! :D

I know what a face and vertex is... but I have no idea how to implement this "vertex to face" collision detection... T_T

Help~~~

If I'm understanding your terms correctly, you're sort of comparing apples and oranges. 'Vertex-to-face' collision isn't really a collision detection method, but rather a specific event that may occur, independent of what method you're using.

It just means that two objects have come into contact, and the features that are in contact are a vertex of one object and a face of the other. There are other possible scenarios, such as edge-to-face or edge-to-edge, but vertex-to-face probably occurs the most frequently.

A vertex-to-face collision could occur using a bounding box method, or using the SAT, or using some other method, but it's not a collision detection 'method' in and of itself.

'Hope that helps clear things up.
