Method Detail

exponent

default float exponent()

The exponent that will be used to modify the generated SSAO term. Higher exponents create occlusion with higher contrast.

Returns:

The SSAO exponent

sampleRadius

default float sampleRadius()

The eye-space radius around the sampling point that will be searched for occluding surfaces. Larger radii will produce softer, more gradual ambient occlusion.

Returns:

The SSAO exponent

kernel

R2SSAOKernelType kernel()

The kernel that will be used for sampling. Larger kernels produce more accurate occlusion terms but increase the cost of processing.

Returns:

The sampling kernel

noiseTexture

R2Texture2DUsableType noiseTexture()

The noise texture that will be used to rotate the sampling hemisphere randomly at each pixel.

Returns:

The noise texture

viewport

com.io7m.jareas.core.AreaInclusiveUnsignedLType viewport()

The viewport of the ambient occlusion buffer to which occlusion terms are written.

Returns:

The framebuffer viewport

viewMatrices

R2MatricesObserverValuesType viewMatrices()

Returns:

The matrices for the current view

geometryBuffer

R2GeometryBufferUsableType geometryBuffer()

Returns:

The geometry buffer that will be sampled
