fp64arithmetic

The fp64arithmetic shader module provides the low-level double-single arithmetic used by fp64. Use it directly when you only need the arithmetic primitives and want to avoid including the full fp64 function library.

Uniforms​

{
  ONE: 'f32',
  SPLIT: 'f32'
}

These uniforms are supplied automatically by the module's defaultUniforms.

Usage​

import {fp64arithmetic} from '@luma.gl/shadertools';

const modules = [fp64arithmetic];

Remarks​

  • fp64 depends on fp64arithmetic, so applications that import fp64 do not usually need to add this module separately.
  • The helper uniforms are part of the module's implementation and should not normally need to be overridden by applications.
