  • Spatial binning of particles on a GPU
    Patent number: 7710417
    Abstract: A method of performing spatial binning of particles is described which can be performed on a graphics processing unit. A stencil buffer is primed with a pattern which controls the writing of data to a framebuffer. A first shader is used to calculate the co-ordinates of the bin in which a particle is located and a second shader is used to write the particle's ID to a location representative of that bin in the framebuffer. The pattern in the stencil buffer ensures that particle data within a bin is not overwritten and the stencil buffer also maintains a record of the number of entries within each bin.
