Module OgamlGraphics.Texture.Texture2D

Represents a simple 2D texture

This module provides an abstraction of OpenGL 2D textures that can be used for 2D rendering (with sprites) or 3D rendering when passed to a GLSL program.

type t

Type of a 2D texture

val create : (module RenderTarget.T with type t = 'a) -> 'a -> ?mipmaps:[ `AllEmpty | `Empty of int | `AllGenerated | `Generated of int | `None] -> [< `File of string | `Image of Image.t | `Empty of OgamlMath.Vector2i.t] -> t

Creates a texture from a source (a file or an image), or an empty texture. Generates all mipmaps by default.
Raises Texture_error if the requested size exceeds the maximal texture size allowed by the context.

See : OgamlGraphics.Context

val size : t -> OgamlMath.Vector2i.t

Returns the size of a texture
See : OgamlMath.Vector2i

val minify : t -> MinifyFilter.t -> unit

Sets the minifying filter of a texture. Defaults as LinearMipmapLinear.

val magnify : t -> MagnifyFilter.t -> unit

Sets the magnifying filter of a texture. Defaults as Linear

val wrap : t -> WrapFunction.t -> unit

Sets the wrapping function of a texture. Defaults as ClampEdge.

val mipmap_levels : t -> int

Returns the number of mipmap levels of a texture

val mipmap : t -> int -> Texture2DMipmap.t

Returns a mipmap level of a texture. Raises Invalid_argument if the requested level is out of bounds

val bind : t -> int -> unit

System only function, binds a texture to a texture unit for drawing

val to_color_attachment : t -> Attachment.ColorAttachment.t

Texture2D implements the interface ColorAttachable and can be attached to an FBO. Binds the mipmap level 0.
