a fast voxel tracersal algorithm for ray tracing
A fast and simple voxel traversal algorithm through a 3D space partition is introduced. Going from one voxel to its neighbour requires only two floating point comparisons and one floating point addition. Also, multiple ray intersections with objects that are in more than one voxel are eliminated....
walk closer to it along a cut plane, and segment it with a region growing algorithm. Our approach structures the whole scene in real time, and allows for a faster revealing of many objects, without changing the viewpoint.
The algorithm first looks for a point in the scene for which the status can be univocally determined. When such a point is found, it propagates its status to the surrounding visible cells. This iterative two-step procedure is repeated for different parts of the scene until the status of ...
Fast Voxel Traversal Algorithm This is an implementation of Amanatides et al. [1]: Given a 3D voxel grid, a starting position and an ending position in 3D space, we shoot a ray from the starting position to the ending position. This algorithm then lists all the voxel ID's being traverse...
这篇文章主要讲在3D空间中,一种简单的体素遍历算法。从一个体素到它临近的体素的计算,只需要去比较两个浮点数,比较后对其中一个添加。当然多条射线在多个物体中交互,在超过一个体素是不能用这种算法的。 在提…
