# IMPORTANT:
|
|
# Shader passes need to know details about the image in the mask_texture LUT
|
|
# files, so set the following constants in user-preset-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 preset, but their
|
|
# compilation model doesn't currently allow the preset file to tell them. Make
|
|
# sure to set the following constants in user-preset-constants.h accordingly too:
|
|
# 1.) bloom_approx_scale_x = scale_x2
|
|
# 2.) mask_resize_viewport_scale = vec2(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)

# scale_x5 == mask_texture_small_size.x (see IMPORTANT above). Larger scales
|
|
# will blur, and smaller scales could get nasty. The vertical size must be
|
|
# based on the viewport size and calculated carefully to avoid artifacts later.
|
|
# First calculate the minimum number of mask tiles we need to draw.
|
|
# Since curvature is computed after the scanline masking pass:
|
|
# num_resized_mask_tiles = 2.0;
|
|
# If curvature were computed in the scanline masking pass (it's not):
|
|
# max_mask_texel_border = ~3.0 * (1/3.0 + 4.0*sqrt(2.0) + 0.5 + 1.0);
|
|
# max_mask_tile_border = max_mask_texel_border/
|
|
# (min_resized_phosphor_triad_size * mask_triads_per_tile);
|
|
# num_resized_mask_tiles = max(2.0, 1.0 + max_mask_tile_border * 2.0);
|
|
# At typical values (triad_size >= 2.0, mask_triads_per_tile == 8):
|
|
# num_resized_mask_tiles = ~3.8
|
|
# Triad sizes are given in horizontal terms, so we need geom_max_aspect_ratio
|
|
# to relate them to vertical resolution. The widest we expect is:
|
|
# geom_max_aspect_ratio = 4.0/3.0 # Note: Shader passes need to know this!
|
|
# The fewer triads we tile across the screen, the larger each triad will be as a
|
|
# fraction of the viewport size, and the larger scale_y5 must be to draw a full
|
|
# num_resized_mask_tiles. Therefore, we must decide the smallest number of
|
|
# triads we'll guarantee can be displayed on screen. We'll set this according
|
|
# to 3-pixel triads at 768p resolution (the lowest anyone's likely to use):
|
|
# min_allowed_viewport_triads = 768.0*geom_max_aspect_ratio / 3.0 = 341.333333
|
|
# Now calculate the viewport scale that ensures we can draw resized_mask_tiles:
|
|
# min_scale_x = resized_mask_tiles * mask_triads_per_tile /
|
|
# min_allowed_viewport_triads
|
|
# scale_y5 = geom_max_aspect_ratio * min_scale_x
|
|
# # Some code might depend on equal scales:
|
|
# scale_x6 = scale_y5
|
|
# Given our default geom_max_aspect_ratio and min_allowed_viewport_triads:
|
|
# scale_y5 = 4.0/3.0 * 2.0/(341.33333 / 8.0) = 0.0625
|
|
# IMPORTANT: The scales MUST be calculated in this way. If you wish to change
|
|
# geom_max_aspect_ratio, update that constant in user-preset-constants.h!
