applyLight()

bool GPUShaders::Common::Forward_lights::applyLight ( GPUPackedLight  gpuLight, vec3  viewSpacePos, vec3  viewSpaceN, textureCubeArray  smapCube, texture2DArray  smap2D, out vec3  l, out float  shadowing  )

inline

Compute a light contribution for a given point in forward shading.

Parameters

gpuLight	the light packed information
viewSpacePos	the point position in view space
viewSpaceN	the surface normal in view space
smapCube	the cube shadow maps
smap2D	the 2D shadow maps
l	will contain the light direction for the point
shadowing	will contain the shadowing factor

Returns

true if the light contributes to the point shading

unpackLight()

Light GPUShaders::Common::Forward_lights::unpackLight ( GPUPackedLight  srcLight )

inline

Convert a forward renderer packed light to the generic shader representation.

Parameters

srcLight

the packed light

Returns

the populated light

unpackProbe()

Probe GPUShaders::Common::Forward_lights::unpackProbe ( GPUPackedProbe  srcProbe )

inline

Convert a forward renderer packed probe to the generic shader representation.

Parameters

srcProbe

the packed probe

Returns

the populated probe
