Struct rendy_core::hal::pso::InputAssemblerDesc

pub struct InputAssemblerDesc {
    pub primitive: Primitive,
    pub with_adjacency: bool,
    pub restart_index: Option<IndexType>,
}

All the information needed to create an input assembler.

Fields

primitive: Primitive

Type of the primitive

with_adjacency: bool

When adjacency information is enabled, every even-numbered vertex (every other starting from the first) represents an additional vertex for the primitive, while odd-numbered vertices (every other starting from the second) represent adjacent vertices.

For example, with [a, b, c, d, e, f, g, h], [a, c, e, g] form a triangle strip, and [b, d, f, h] are the adjacent vertices, where b, d, and f are adjacent to the first triangle in the strip, and d, f, and h are adjacent to the second.

restart_index: Option<IndexType>

Describes whether or not primitive restart is supported for an input assembler. Primitive restart is a feature that allows a mark to be placed in an index buffer where it is is "broken" into multiple pieces of geometry.

See https://www.khronos.org/opengl/wiki/Vertex_Rendering#Primitive_Restart for more detail.

Implementations
