@novorender/api / FillrateProfiler

Class: FillrateProfiler

Defined in: @novorender/src/core3d/benchmark/fillrate.ts:15

A basic GPU fill rate profiler.

Constructors​

Constructor​

new FillrateProfiler(benchmark, shaders): FillrateProfiler;

Defined in: @novorender/src/core3d/benchmark/fillrate.ts:23

Parameters​

ParameterTypeDescription
benchmarkBenchmarkThe benchmark context to use.
shaders{ fillrate: { fragmentShader: string; vertexShader: string; }; pointrate: { fragmentShader: string; vertexShader: string; }; }The shader imports.
shaders.fillrate{ fragmentShader: string; vertexShader: string; }-
shaders.fillrate.fragmentShaderstring-
shaders.fillrate.vertexShaderstring-
shaders.pointrate{ fragmentShader: string; vertexShader: string; }-
shaders.pointrate.fragmentShaderstring-
shaders.pointrate.vertexShaderstring-

Returns​

FillrateProfiler

Methods​

measure()​

measure(): Promise<number>;

Defined in: @novorender/src/core3d/benchmark/fillrate.ts:40

Measure fill rate by rendering a series of noisy, semi-transparent quads.

Returns​

Promise<number>

Fill rate estimate in pixels/second.

Remarks​

This test is quite inaccurate and does not match close to the nominal fill rate of a GPU, particularly on tile based mobile GPUs. The result should only serve as a rough estimate.
