Classes

`ColorSpace`	RGB color spaces used at Newton rendering boundaries.
`EventTracer`	Calculates elapsed times of functions annotated with event_scope.
`MeshAdjacency`	Connectivity tables of a soft (triangle) mesh, consumed by collision and the solvers.
`MeshAdjacencyData`	Kernel-facing soft-mesh adjacency -- pure data, no Python state or methods.

Functions

`bourke_color_map`(low, high, v)	Map a scalar value to an RGB color using Bourke's color ramp.
`color_graph`(num_nodes, graph_edge_indices[, ...])	A function that generates coloring for a graph, which is represented by the number of nodes and an array of edges.
`color_linear_to_srgb`(color)	Convert a linear RGB triple to sRGB/display encoding.
`color_srgb_to_linear`(color)	Convert an sRGB/display RGB triple to linear Rec.709.
`compute_world_offsets`(world_count, spacing)	Compute positional offsets for multiple worlds arranged in a grid.
`download_asset`(asset_folder[, cache_dir, ...])	Download a specific folder from the newton-assets GitHub repository into a local cache.
`event_scope`(fn[, name])	Wraps a function and records an event before and after the function invocation.
`load_texture`(texture)	Normalize a texture input into a contiguous image array.
`normalize_texture`(texture_image, *[, ...])	Normalize a texture array for rendering.
`plot_graph`(vertices, edges[, edge_labels, ...])	Plots a graph using matplotlib and networkx.
`rasterize_mesh_to_heightfield`(mesh, ...[, ...])	Rasterize a triangle mesh into a heightfield elevation grid.
`remesh_mesh`(mesh[, method, ...])	Remeshes a Mesh object using the specified remeshing method.
`run_benchmark`(benchmark_cls[, number, ...])	Simple scaffold to run a benchmark class.
`solidify_mesh`(faces, vertices, thickness)	Convert a surface mesh into a solid mesh by extruding along face normals.
`string_to_warp`(value, warp_dtype[, default])	Parse a Warp value from a string.
`validate_tet_mesh`(vertices, indices, *[, ...])	Check a tetrahedral mesh for quality issues and emit warnings.
`validate_triangle_mesh`(vertices, indices, *)	Check a triangle mesh for quality issues and emit warnings.

Deprecated

Name	Guidance
`CableStiffness`	Deprecated in 1.6; pass direct stiffness values to `newton.ModelBuilder.add_rod()` instead.
`create_cable_stiffness_from_elastic_moduli`	Deprecated in 1.6; supply elastic material through `newton.Rod(...)` or pass direct stiffness values to `newton.ModelBuilder.add_rod()` instead.
`create_parallel_transport_cable_quaternions`	Deprecated in 1.6; construct `rod = newton.Rod(points)` and read `rod.quaternions` instead. For nonzero `twist_total`, first call `rod.compute_frames(twist_total=twist_total)`.
`create_straight_cable_points`	Deprecated in 1.6; use `newton.Rod.create_straight(...).points` instead.
`create_straight_cable_points_and_quaternions`	Deprecated in 1.6; use `newton.Rod.create_straight(...)` instead.
