type Texture struct {
	// contains filtered or unexported fields
}

Texture represents a power-of-two 2D texture. The power-of-two means that the texture width and height must be a power of two. e.g. 1024x1024.

func NewColorTexture(c color.RGBA) *Texture

func NewTexture(opts ...TextureOption) *Texture

func (t *Texture) Query(lod, u, v float64) color.RGBA

Query fetches the color of at pixel (u, v). This function is a naive mipmap implementation that does magnification and minification.

func (t *Texture) Size() int

Size returns the size of the texture.

func (t *Texture) UseMipmap() bool

UseMipmap checks if the texture activates mipmap.

type TextureOption func(t *Texture)

func WithDebug(enable bool) TextureOption

func WithIsotropicMipMap(enable bool) TextureOption

func WithSource(data *image.RGBA) TextureOption
