HLSL-Related Enable Switches
|
|
----------------------------
|
|
|
|
Name Values Description
|
|
hlsl_enable 0/1 Enables HLSL post-processing in Direct3D 9 modes.
|
|
yiq_enable 0/1 Enables YIQ-colorspace post-processing. Causes a
|
|
performance drop but gives a much more authentic
|
|
NTSC TV appearance on TV-based systems when configured
|
|
properly.
|
|
hlslpath [path] Path to the .fx files that are in use.
|

Color-Processing Parameters
|
|
---------------------------
|
|
|
|
Name Values Description
|
|
red_from_r -2.0 to 2.0 These parameters define a 3x3 matrix which is multiplied
|
|
red_from_g -2.0 to 2.0 by the incoming RGB signal. This can be used for any
|
|
red_from_b -2.0 to 2.0 standard matrix convolution, including H/S/V or simply
|
|
green_from_r -2.0 to 2.0 affecting the TV-style tint.
|
|
green_from_g -2.0 to 2.0
|
|
green_from_b -2.0 to 2.0
|
|
blue_from_r -2.0 to 2.0
|
|
blue_from_g -2.0 to 2.0
|
|
blue_from_b -2.0 to 2.0
|
|
red_scale -2.0 to 2.0 These parameters define a value for each color channel
|
|
green_scale -2.0 to 2.0 that is multiplied with said channel after matrix
|
|
blue_scale -2.0 to 2.0 convolution.
|
|
red_offset -1.0 to 1.0 These parameters define a value for each color channel
|
|
green_offset -1.0 to 1.0 that is added to said channel after scaling and after
|
|
blue_offset -1.0 to 1.0 matrix convolution.
|
|
saturation 0.0 to 4.0 This parameter defines the amount each color channel is
|
|
raised above said channel's baseline grayscale value.
|
|
A value of 0.0 gives a gamma-correct grayscale image,
|
|
whereas 1.0 is full saturation, with each channel being
|
|
oversaturated equally beyond that.
|
|
red_power -4.0 to 4.0 These parameters define the exponent for each color
|
|
green_power -4.0 to 4.0 channel that is applied after scaling, offsetting,
|
|
blue_power -4.0 to 4.0 saturation and matrix convolution.
|
|
red_floor 0.0 to 1.0 These parameters define the lower limit of each final
|
|
green_floor 0.0 to 1.0 color channel value; 0.05, for example, raises the
|
|
blue_floor 0.0 to 1.0 minimum to 0.05 but re-scales to leave the max at 1.0.
|
|
|
|
|
|
Convergence-Processing Parameters
|
|
---------------------------------
|
|
|
|
Name Values Description
|
|
red_converge_x -150 to 150 These parameters define the overall convergence, in pixel
|
|
red_converge_y -150 to 150 space, for each channel. Radial convergence occurs
|
|
green_converge_x -150 to 150 relative to the center of the screen, whereas the other
|
|
green_converge_y -150 to 150 six define overall translation values.
|
|
blue_converge_x -150 to 150
|
|
blue_converge_y -150 to 150
|
|
red_radial_converge_x -150 to 150
|
|
red_radial_converge_y -150 to 150
|
|
green_radial_converge_x -150 to 150
|
|
green_radial_converge_y -150 to 150
|
|
blue_radial_converge_x -150 to 150
|
|
blue_radial_converge_y -150 to 150
|
|
defocus_x 0.0 to 32.0 These parameters define the overall defocus radius for
|
|
defocus_y 0.0 to 32.0 the three post-converged beams.
|
|
|
|
|
|
Front-Surface Processing Parameters

-----------------------------------
|
|
|
|
Name Values Description
|
|
red_phosphor_life 0.0 to 1.0 These parameters define the phosphor lifetime for each
|
|
green_phosphor_life 0.0 to 1.0 channel, with 0.0 representing no phosphorescence and
|
|
blue_phosphor_life 0.0 to 1.0 1.0 leaving the channel on indefinitely.
|
|
scanline_alpha 0.0 to 1.0 The overall darkness of each scanline furrow.
|
|
scanline_size 0.0 to 4.0 The overall height of each scanline.
|
|

|
|
scanline_jitter 0.0 to 2.0 The relative scanline movement per field.
|
|
shadow_mask_alpha 0.0 to 1.0 The ovearll darkness of each shadow mask pixel.
|
|
shadow_mask_texture [filename] A PNG that defines the shadow mask for each pixel.
|
|
shadow_mask_x_count 1+ The count of shadow mask elements, X (usually 640-ish)

|
|

|
|
shadow_mask_vsize 0.0 to 1.0 X and Y axes of the shadow mask texture.
|
