Each scene contains the following images:
vao: base line vao with a single depth buffer
vao_dual: vao with an additional depth peeled layer
vao_stochastic: vao with an 4spp stochastic depth map
vao_ray: vao with ray tracing
bitmask: from the paper
sdmask: from the paper
vao_heatmap: AO value multiplied with ray types. Green = valid first hit, Red = occluded first hit (raytracing required), Blue = invalid first hit (ignored)
hbao: HBAO+
hbao_dual: HBAO+ with an additional depth peeled layer
hbao_stochastic: HBAO+ with an 4spp stochastic depth map
