Functions

func RegisterHandler

func RegisterHandler(name string, create func() (Handler, error)) error

RegisterHandler is called by handlers to register their creation functions.

Types

type Handler

type Handler interface {
	Init(proc *Proc, datastring string, userdata interface{}) error
}

Handler is the type of procedural generation/loading handlers.

type Proc

type Proc struct {
	NodeDef  core.NodeDef `node:"-"`
	NodeName string       `node:"Name"`

	Handler string

	DataString string      `node:"Data"`
	Userdata   interface{} `node:"-"`

	Geom   []core.Geom   `node:"-"`
	Shader []core.Shader `node:"-"`

	BMin param.PointArray
	BMax param.PointArray

	Transform param.MatrixArray `node:",opt"`
	// contains filtered or unexported fields
}

Proc supports procedural loading/generation of geometry via handlers. Handlers may create Geom or Shader nodes.

func (*Proc) Bounds

func (proc *Proc) Bounds(time float32) m.BoundingBox

Bounds implements core.Geom.

func (*Proc) Def

func (proc *Proc) Def() core.NodeDef

Def is a core.Node method.

func (*Proc) MotionKeys

func (proc *Proc) MotionKeys() int

MotionKeys returns the number of motion keys.

func (*Proc) Name

func (proc *Proc) Name() string

Name is a core.Node method.

func (*Proc) PostRender

func (proc *Proc) PostRender() error

PostRender is a core.Node method.

func (*Proc) PreRender

func (proc *Proc) PreRender() error

PreRender is a core.Node method.

func (*Proc) Trace

func (proc *Proc) Trace(ray *core.Ray, sg *core.ShaderContext) bool

Trace implements core.Primitive.

type TransformSRTArray

type TransformSRTArray []m.TransformDecomp

TransformSRTArray is an array of Transforms supporting lerp.

func (*TransformSRTArray) TimeKey

func (t *TransformSRTArray) TimeKey(time float32) m.TransformDecomp

TimeKey returns the interpolated transform from the array (whole array is assumed to cover [0,1) linearly. This should be altered to allow time to be non-linearly related to the keys.
