Crate kgltf

A minimal crate for loading glTF.

This crate is auto-generated from the specification’s Json Schema, so some comments may not exactly match the Rust names.

Structs

Accessor	A typed view into a bufferView. A bufferView contains raw binary data. An accessor provides a typed view into a bufferView or a subset of a bufferView similar to how WebGL’s vertexAttribPointer() defines an attribute in a buffer.
AccessorSparse	Sparse storage of attributes that deviate from their initialization value.
AccessorSparseIndices	Index array of size count that points to those accessor attributes that deviate from their initialization value. Indices must strictly increase.
AccessorSparseValues	Array of size count times number of components, storing the displaced accessor attributes pointed by indices. Substituted values must have the same componentType and number of components as the base accessor.
Animation	A keyframe animation.
AnimationChannel	Targets an animation’s sampler at a node’s property.
AnimationChannelTarget	The index of the node and TRS property to target.
AnimationSampler	Combines input and output accessors with an interpolation algorithm to define a keyframe graph (but not its target).
Asset	Metadata about the glTF asset.
Buffer	A buffer points to binary geometry, animation, or skins.
BufferView	A view into a buffer generally representing a subset of the buffer.
Camera	A camera’s projection. A node can reference a camera to apply a transform to place the camera in the scene.
CameraOrthographic	An orthographic camera containing properties to create an orthographic projection matrix.
CameraPerspective	A perspective camera containing properties to create a perspective projection matrix.
Extension	Dictionary object with extension-specific objects.
GLB	A GLTF with all of its data included within a buffer.
GlTf	The root object for a glTF asset.
Image	Image data used to create a texture. Image can be referenced by URI or bufferView index. mimeType is required in the latter case.
Material	The material appearance of a primitive.
MaterialNormalTextureInfo	The normal map texture.
MaterialOcclusionTextureInfo	The occlusion map texture.
MaterialPbrMetallicRoughness	A set of parameter values that are used to define the metallic-roughness material model from Physically-Based Rendering (PBR) methodology. When not specified, all the default values of pbrMetallicRoughness apply.
Mesh	A set of primitives to be rendered. A node can contain one mesh. A node’s transform places the mesh in the scene.
MeshPrimitive	Geometry to be rendered with the given material.
Node	A node in the node hierarchy. When the node contains skin, all mesh.primitives must contain JOINTS_0 and WEIGHTS_0 attributes. A node can have either a matrix or any combination of translation/rotation/scale (TRS) properties. TRS properties are converted to matrices and postmultiplied in the T * R * S order to compose the transformation matrix; first the scale is applied to the vertices, then the rotation, and then the translation. If none are provided, the transform is the identity. When a node is targeted for animation (referenced by an animation.channel.target), only TRS properties may be present; matrix will not be present.
Sampler	Texture sampler properties for filtering and wrapping modes.
Scene	The root nodes of a scene.
Skin	Joints and matrices defining a skin.
Texture	A texture and its sampler.
TextureInfo	The base color texture.

Enums

AccessorComponentType	The datatype of components in the attribute.
AccessorSparseIndicesComponentType	The indices data type.
AccessorType	Specifies if the attribute is a scalar, vector, or matrix.
AnimationChannelTargetPath	The name of the node’s TRS property to modify, or the “weights” of the Morph Targets it instantiates. For the “translation” property, the values that are provided by the sampler are the translation along the x, y, and z axes. For the “rotation” property, the values are a quaternion in the order (x, y, z, w), where w is the scalar. For the “scale” property, the values are the scaling factors along the x, y, and z axes.
AnimationSamplerInterpolation	Interpolation algorithm.
BufferViewTarget	The target that the GPU buffer should be bound to.
CameraType	Specifies if the camera uses a perspective or orthographic projection.
GLBError
ImageMimeType	The image’s MIME type. Required if bufferView is defined.
MaterialAlphaMode	The alpha rendering mode of the material.
MeshPrimitiveMode	The type of primitives to render.
SamplerMagFilter	Magnification filter.
SamplerMinFilter	Minification filter.
SamplerWrapS	s wrapping mode.
SamplerWrapT	t wrapping mode.
