WebGLRenderer Constants

Cull Face Modes

v3d.CullFaceNone v3d.CullFaceBack v3d.CullFaceFront v3d.CullFaceFrontBack

CullFaceNone disables face culling.
CullFaceBack culls back faces (default).
CullFaceFront culls front faces.
CullFaceFrontBack culls both front and back faces.

Front Face Direction

v3d.FrontFaceDirectionCW v3d.FrontFaceDirectionCCW

FrontFaceDirectionCW sets the winding order for polygons to clockwise.
FrontFaceDirectionCCW sets the winding order for polygons to counter-clockwise (default).

Shadow Types

v3d.BasicShadowMap v3d.PCFShadowMap v3d.PCFSoftShadowMap

These define the WebGLRenderer's shadowMap.type property.

BasicShadowMap gives unfiltered shadow maps - fastest, but lowest quality.
PCFShadowMap filters shadow maps using the Percentage-Closer Filtering (PCF) algorithm (default).
PCFSoftShadowMap filters shadow maps using the Percentage-Closer Soft Shadows (PCSS) algorithm.

Tone Mapping

v3d.NoToneMapping v3d.LinearToneMapping v3d.ReinhardToneMapping v3d.Uncharted2ToneMapping v3d.CineonToneMapping

These define the WebGLRenderer's toneMapping property. This is used to approximate the appearance of high dynamic range (HDR) on the low dynamic range medium of a standard computer monitor or mobile device's screen.

NoToneMapping disables tone mapping.
LinearToneMapping is the default.

See the WebGL / tonemapping example.
