textured_mesh_rect()

MAYAFLUX_API std::array< Kakshya::MeshVertex, 6 > MayaFlux::Kinesis::textured_mesh_rect	(	Kinesis::AABB2D	region,
		float	weight = 0.F,
		glm::vec3	color = glm::vec3(1.F)
	)

Generate a UV-mapped TRIANGLE_LIST quad (6 vertices, 2 triangles) from an AABB2D, as Kakshya::MeshVertex.

UV origin is bottom-left (0,1), same convention as textured_rect(). Use this instead of textured_rect() when the target pipeline expects the full MeshVertex layout (color/weight/normal/tangent) rather than texture.vert.spv's plain position+texcoord input - textured_rect()'s TextureQuadVertex is not wire-compatible with a MeshVertex shader input.

weight is written through unchanged, defaulting to MeshVertex's own neutral default (0). What it means - a blend factor, a sampler selector, anything - is entirely the caller's domain; this function has no opinion on it. color is likewise written through unchanged, defaulting to MeshVertex's own neutral default (white) - at weight >= 1 a caller-side shader convention may read it as a texture tint; at weight <= 0 the same convention may render it as a flat fill with no texture read at all. Either reading is the caller's domain.

Parameters

region	NDC axis-aligned bounds.
weight	Per-vertex weight value, written through as-is.
color	Per-vertex color value, written through as-is.
