Enum dae_parser::SurfaceInit

pub enum SurfaceInit {
    Null,
    Target,
    From {
        mip: u32,
        slice: u32,

    },
}

A Surface initialization option, which specifies whether to initialize the surface and how to do so.

Variants

Null

This surface is intended to be initialized later externally by a EffectSetParam element. If it is used before being initialized, there is profile- and platform-specific behavior. Most elements on the Surface element that contains this will be ignored, including mip_levels, mipmap_generate, size, viewport_ratio, and format.

Target

Initializes this surface as a target for depth, stencil, or color. It does not need image data. If this element is used, mipmap_generate is ignored.

From

Fields

mip: u32

The MIP level.

slice: u32

Which 2D layer within a volume to initialize. There are anywhere from 0 to n slices in a volume, where n is the volume’s depth slice. This attribute is used in combination with mip because a volume might have MIPmaps.

face: SurfaceFace

Which surface of a cube to initialize from the specified image. This attribute is used in combination with mip because a cubemap might have MIPmaps.

image: NameRef<Image>

Each subsurface is initialized by a common 1-D or 2-D image, not a complex compound image such as DDS.

Contains a reference to a 1D or 2D image. Initializes the surface one subsurface at a time by specifying combinations of mip, face, and slice that make sense for a particular surface type. Each subsurface is initialized by a common 1-D or 2-D image, not a complex compound image such as DDS. If not all subsurfaces are initialized, the surface is invalid and will result in profile- and platform-specific behavior unless mipmap_generate is responsible for initializing the remaining subsurfaces.
