详细描述

Orthographic surface capture that rebuilds height + normals on a SurfaceField.

P2 CPU path: project triangle meshes into an XZ heightfield (max height wins), then rebuild normals from central differences. Graphics depth-texture capture is a follow-up that writes the same SurfaceField layout.

◆ captureFromTriangles()

Result< void > eve::gpuagents::SurfaceCapture::captureFromTriangles	(	SurfaceField &	out,
		std::span< const glm::vec3 >	positions,
		std::span< const std::uint32_t >	indices,
		const glm::vec3 &	originMin,
		float	worldSize,
		int	resolution,
		float	baseHeight = `0.f`
	)

static

Bake triangle positions into out over the given XZ domain.

参数

out	Destination surface (reinitialized).
positions	Vertex positions (world space).
indices	Triangle indices (3 per face).
originMin	World-space corner of texel (0,0).
worldSize	Side length of the square domain on XZ.
resolution	Texel resolution (>= 2).
baseHeight	Height written where no triangle covers a texel. @ownership Borrowed spans; not retained. @lifetime Input spans valid only for the duration of the call.
