Enum StateParam 

pub enum StateParam {
    Projected(u32),
    TextureDim(u32),
    BumpEnvMat(u32),
    BumpLScale(u32),
    BumpLOffset(u32),
}

A piece of pipeline state a program reads (Op::LoadState), by the stage or unit it belongs to. A known one is folded into literals by specialisation; an unknown numeric one is carried in a state block the binding plan places; an unknown one that changes types (a texture’s dimension) has no uniform form.

Variants

Projected(u32)

Whether texture stage n divides its coordinate by its last lane before sampling (D3D9’s D3DTTFF_PROJECTED): a bool.

TextureDim(u32)

The dimension of the texture bound to stage n (what D3D9’s ps_1_x tex samples): a u32, the TextureDim::state_code of it. It changes the type of the sample, so only specialisation lowers it.

BumpEnvMat(u32)

Stage n’s bump environment matrix (D3D9’s D3DTSS_BUMPENVMAT00, 01, 10, 11, in that order): a vec4<f32>.

BumpLScale(u32)

Stage n’s bump luminance scale (D3D9’s D3DTSS_BUMPENVLSCALE): an f32.

BumpLOffset(u32)

Stage n’s bump luminance offset (D3D9’s D3DTSS_BUMPENVLOFFSET): an f32.
