# IMPORTANT:

# Shader passes need to know details about the image in the mask_texture LUT
|
|
# files, so set the following constants in user-cgp-constants.h accordingly:
|
|
# 1.) mask_triads_per_tile = (number of horizontal triads in mask texture LUT's)
|
|
# 2.) mask_texture_small_size = (texture size of mask*texture_small LUT's)
|
|
# 3.) mask_texture_large_size = (texture size of mask*texture_large LUT's)
|
|
# 4.) mask_grille_avg_color = (avg. brightness of mask_grille_texture* LUT's, in [0, 1])
|
|
# 5.) mask_slot_avg_color = (avg. brightness of mask_slot_texture* LUT's, in [0, 1])
|
|
# 6.) mask_shadow_avg_color = (avg. brightness of mask_shadow_texture* LUT's, in [0, 1])
|
|
# Shader passes also need to know certain scales set in this .slangp, but their
|
|
# compilation model doesn't currently allow the .slangp file to tell them. Make
|
|
# sure to set the following constants in user-cgp-constants.h accordingly too:
|
|
# 1.) bloom_approx_scale_x_for_fake = scale_x2
|
|
# 2.) mask_resize_viewport_scale = float2(scale_x6, scale_y5)
|
|
# Finally, shader passes need to know the value of geom_max_aspect_ratio used to
|
|
# calculate scale_y5 (among other values):
|
|
# 1.) geom_max_aspect_ratio = (geom_max_aspect_ratio used to calculate scale_y5)

|

|
|
# a.) 400x300 is a good compromise for the "fake-bloom" version: It's low enough
|
|
# to blur high-res/interlaced sources but high enough that resampling
|
|
# doesn't smear low-res sources too much.
|
|
# b.) 320x240 works well for the "real bloom" version: It's 1-1.5% faster, and
|
|
# the only noticeable visual difference is a larger halation spread (which
|
|
# may be a good thing for people who like to crank it up).
