WebFeb 3, 2024 · We can reach the plane (means intersect at point p) using the parametric form: l0 + l * t = p (ii) If the ray isn’t parallel to the plane, then t times in the direction of the ray; the ray will interest the plane. Next, we can put the value of p from equation (ii) into the equation (i), and we get: (l0 + l * t – p0) . n = 0. WebTask 2: Ray-AABB intersection. Chapter 3 of the book discusses how to build a bounding volume hierarchy so you can intersect rays quickly against a large collection of triangles or other geometric primitives. The first step in this approach is to choose what kind of bounding volume to use. We will stick with axis-aligned bounding boxes (or AABBs).

Web如果这个物体不是三角形，那么调用intersection shader，由用户自定义这个物体的相交行为。 如果是三角形，调用DRX自带的三角形相交。 如果相交，且是到目前为止最近的交点，对透明物体调用 any hit shader ，决定是否进行相交测试（如果不提供any hit，当做不透明物体处理），否则直接更新TMax。 WebAt the top of the fragment shader, perform a ray-cube intersection. Raycasting on front-faces instead of a full-screen quad allows you to avoid the need to test for intersection failure. Traditional raycasting shaders issue a discard if there’s no intersection with the view volume, but since we’re guaranteed to hit the viewing volume, so there’s no need.

WebAABBs are used to surround groups of primitives (e.g. spheres and triangles). Before testing ray intersection with any of the primitives in the group, the ray is tested for intersection with the AABB. If the ray does not intersect the AABB, it doesn't intersect any of the primitives, so those primitives don't have to be tested.
