XML Blends - ixray-team/ixray-1.6-stcop GitHub Wiki

XML Blends - альтернативная система компиляции шейдеров, представляющая дальнейшую замену Lua компиляции шейдеров. Ниже предоставлен пример эквивалентный между XML и Lua.

• Lua:

function normal(shader, t_base, t_second, t_detail)
    shader:begin("accum_volumetric", "accum_volumetric")
	
        :fog(false)
        :zb(true, false)
        :blend(true, blend.one, blend.one)
        :sorting(2, false)

    shader:dx10texture("s_lmap", t_base)
    shader:dx10texture("s_smap", "null")
    shader:dx10texture("s_noise", "fx\\fx_noise")

    shader:dx10sampler("smp_rtlinear")
    shader:dx10sampler("smp_linear")
    shader:dx10sampler("smp_smap")
end

• XML:

<w>
    <element_0 ps="accum_volumetric" vs="accum_volumetric" fog="0" zread="1" zwrite="0">
        <blend status="1" src="one" dest="one" />
        <sort status="0" count="2" />

        <texture name="s_lmap" rt="t_base" />
        <texture name="s_smap" rt="null" />
        <texture name="s_noise" rt="fx\\fx_noise" />

        <sampler name="smp_rtlinear" />
        <sampler name="smp_linear" />
        <sampler name="smp_smap" />
    </element_0>
