Types

AnimBone

struct

type AnimBone struct {
    NodeIndex     int
    PathType      AnimationPathType
    Interpolation AnimationInterpolation
    // Could be Vec3 or Quaternion, doing this because Go doesn't have a union
    Data [4]matrix.Float
}

AnimKeyFrame

type AnimKeyFrame struct {
    Bones []AnimBone
    Time  float32
}

AnimationInterpolation

type AnimationInterpolation = int

const ( AnimInterpolateInvalid AnimationInterpolation = iota - 1 AnimInterpolateLinear AnimInterpolateStep AnimInterpolateCubicSpline )

KaijuMesh

struct

type KaijuMesh struct {
    Name       string
    Verts      []rendering.Vertex
    Indexes    []uint32
    Animations []KaijuMeshAnimation
    Joints     []KaijuMeshJoint
}

KaijuMesh is a base primitive representing a single mesh. This is the archived format of the authored meshes. Typically this structure is created by loading in a mesh using something like [loaders.GLTF] and then converting the result of that using LoadedResultToKaijuMesh. From this point, it is typically serialized and stored into the content database. When reading a mesh from the content database, it will return a KaijuMesh.

Deserialize

func Deserialize(data []byte) (KaijuMesh, error)

Deserialize will construct a KaijuMesh from the given array of bytes. This deserialization uses the built-in gob.Decoder

LoadedResultToKaijuMesh

func LoadedResultToKaijuMesh(res load_result.Result) []KaijuMesh

LoadedResultToKaijuMesh will take in a load_result.Result and convert every mesh contained within the structure to our built in version known as KaijuMesh. This is typically used for the editor, but games/applications may find some use for it.

ReadMesh

func ReadMesh(id string, host *engine.Host) (KaijuMesh, error)

KaijuMesh.GenerateBVH

func (k KaijuMesh) GenerateBVH(threads *concurrent.Threads, transform *matrix.Transform, data any) *collision.BVH

KaijuMesh.Serialize

func (k KaijuMesh) Serialize() ([]byte, error)

Serialize will convert a KaijuMesh into a byte array for saving to the database or later use. This serialization uses the built-in gob.Encoder

KaijuMeshAnimation

struct

type KaijuMeshAnimation struct {
    Name   string
    Frames []AnimKeyFrame
}

KaijuMeshJoint

struct

type KaijuMeshJoint struct {
    Id       int32
    Parent   int32
    Skin     matrix.Mat4
    Position matrix.Vec3
    Rotation matrix.Vec3
    Scale    matrix.Vec3
}
