ray ban 3d model

IntroductionIn the previous section, I described how to implement a ray-to-triangle cross-detection algorithm. However, we should know that in game development, a model has a lot of triangles, if you want to all objects, all the triangles to do this detection, even if the current computer computing ability, is not efficient to complete. Therefore, we need to use other means to remove some of the objects tha

even if there is no collision. So again, you can improve the accuracy by performing Ray and ball Collision Detection on small ball surrounded by different modelmesh models. Large and fast objects The collision detection method described earlier requires that fast objects be very small, similar to a point in 3D space. However, when a fast object cannot be regarded as a point, you need to regard it as a ball

C # programmer's Unity 3D note (10): Unity3D mathematical model of displacement and Rotation?? The core reason is that the concept of 3D mathematics in U3D is not flexible enough. So the system learns again-the third learning 3D mathematics. This time, we hope to implement the following simple functions: For exampl

. These two rays use the octal tree of the spatial model to obtain the intersection position of the 3D model, and obtain the method vector of the intersection and the distance from the intersection to the intersection, then, based on the relationship between these two vectors, we can determine whether the current element is inside the
