Systems and methods for ray intersection for primitives are described. The primitive data is efficiently encoded into an array of data blocks of fixed size using a data format that can directly consume for ray traversal. The vertex data in the block is pre-quantized and stored using a fixed bit quantization grid. Mesh connectivity is encoded using triangular stripes based on control values representing triangular interconnectivity and a compressed index buffer storing indices of vertices in each stripe. Alternatively, the primitives may be quantized to generate primitive packets that are stored compactly in, with, or near leaf nodes of the acceleration structure. A low precision intersection tester simultaneously tests light for primitives to find candidate triangles that require full precision intersection. The primitives that generate uncertain results during the low precision test are retested using a full precision tester to explicitly determine a ray-triangle hit or miss.
