Types ¶

type ClipMode ¶

type ClipMode int

const (
	ClipExtend ClipMode = iota
	Clip
	ClipCube
	ClipRepeat
)

type ImageLoader ¶

type ImageLoader interface {
	LoadImage(name string) (img *goray.Image, err error)
}

ImageLoader is an interface for retrieving images with a name.

func NewImageLoader ¶

func NewImageLoader(base string) ImageLoader

NewImageLoader creates an image loader that defaults to the given directory. Users of the loader can access anything in local storage.

func NewImageLoaderDirectory ¶

func NewImageLoaderDirectory(base string) ImageLoader

NewImageLoaderDirectory creates an image loader that is rooted at a given directory. Users of the loader will not directly be able to access anything outside the directory, but symlinks inside the directory will be followed.

type ImageLoaderFunc ¶

type ImageLoaderFunc func(string) (*goray.Image, error)

ImageLoaderFunc uses a function to perform loads.

func (ImageLoaderFunc) LoadImage ¶

func (f ImageLoaderFunc) LoadImage(name string) (img *goray.Image, err error)

type Interpolation ¶

type Interpolation int

const (
	NoInterpolation Interpolation = 0
	Bilinear
	Bicubic
)

type Texture ¶

type Texture struct {
	Image         *goray.Image
	Interpolation Interpolation
	UseAlpha      bool

	ClipMode         ClipMode
	RepeatX, RepeatY int
}

func (*Texture) ColorAt ¶

func (t *Texture) ColorAt(pt vec64.Vector) (col color.AlphaColor)

func (*Texture) Is3D ¶

func (t *Texture) Is3D() bool

func (*Texture) IsNormalMap ¶

func (t *Texture) IsNormalMap() bool

func (*Texture) Resolution ¶

func (t *Texture) Resolution() (x, y, z int)

func (*Texture) ScalarAt ¶

func (t *Texture) ScalarAt(pt vec64.Vector) float64
