3D Engine Design

Welcome to the 3D Engine Design section of this edition of GPU Pro.The

selection of chapters you will find in here covers a range of engine design problems.

First, Holger Gruen examines the benefits of a block-wise linear memory lay-

out for binary 3D grids in the chapter “Block-Wise Linear Binary Grids for

Fast Ray-Casting Operations.” This memory layout allows mapping a number

of volumetric intersection algorithms to binary

AND operations. Bulk-testing a

subportion of the voxel grid against a volumetric stencil becomes possible. The

chapter presents various use cases for this memory layout optimization.

Second, Michael Delva, Julien ...
