struct ludus::foundation::geometry::SurfaceMeshPatch final

Fields¶

usize ludus::foundation::geometry::SurfaceMeshPatch::LevelU = 0

2^LevelU cells along u.

Related types: usize

usize ludus::foundation::geometry::SurfaceMeshPatch::LevelV = 0

2^LevelV cells along v.

Related types: usize

usize ludus::foundation::geometry::SurfaceMeshPatch::FirstVertex = 0

First render vertex; vertex (i, j) is FirstVertex + i * (2^LevelV + 1) + j.

Related types: usize

usize ludus::foundation::geometry::SurfaceMeshPatch::VertexCount = 0

(2^LevelU + 1) * (2^LevelV + 1).

Related types: usize

usize ludus::foundation::geometry::SurfaceMeshPatch::FirstIndex = 0

First entry of this patch's triangles in SurfaceMeshView::Indices.

Related types: usize

usize ludus::foundation::geometry::SurfaceMeshPatch::IndexCount = 0

6 * 2^LevelU * 2^LevelV.

Related types: usize

float64 ludus::foundation::geometry::SurfaceMeshPatch::PositionBound = 0.0

Certified largest distance between a cell and its two triangles.

Related types: float64

float64 ludus::foundation::geometry::SurfaceMeshPatch::NormalAngleEstimate = 0.0

Estimated largest sampled normal angle in a cell, radians.

Related types: float64

bool ludus::foundation::geometry::SurfaceMeshPatch::IsWithinTolerance = false

Both bounds fit the profile; false only for an accepted coarser grid.
