Struct three_d::renderer::geometry::Instances

pub struct Instances {
    pub translations: Vec<Vec3>,
    pub rotations: Option<Vec<Quat>>,
    pub scales: Option<Vec<Vec3>>,
    pub texture_transforms: Option<Vec<Mat3>>,
    pub colors: Option<Vec<Color>>,
}

Defines the attributes for the instances of the model defined in InstancedMesh or InstancedModel. Each list of attributes must contain the same number of elements as the number of instances. The attributes are applied to each instance before they are rendered. The translation, rotation and scale is applied after the transformation applied to all instances (see InstancedMesh::set_transformation). The texture transform is also applied after the texture transform applied to all isntances (see InstancedMesh::set_texture_transform).

Fields

translations: Vec<Vec3>

The translation applied to the positions of each instance.

rotations: Option<Vec<Quat>>

The rotations applied to the positions of each instance.

scales: Option<Vec<Vec3>>

The non-uniform scales applied to the positions of each instance.

texture_transforms: Option<Vec<Mat3>>

The texture transform applied to the uv coordinates of each instance.

colors: Option<Vec<Color>>

Colors multiplied onto the base color of each instance.

Implementations

impl Instances

pub fn validate(&self) -> ThreeDResult<()>
